Justified True Belief

(●) The Alexandrian priest whose account of the Son of God forced the whole church to say, in one word, what it believed about Jesus Christ. + Most Christians have never read a line of Arius, and most Christians recite an answer to him every Sunday. The Nicene Creed, the confession shared by Roman Catholics, Eastern Orthodox, Anglicans, Lutherans, Presbyterians and a great many others, exists because a middle-aged priest in Egypt said something about Jesus that his bishop could not let pass. "God from God, Light from Light, true God from true God, begotten, not made, of one substance with the Father": every clause of that is aimed at him. He is on a Christian apologetics shelf for two reasons. The first is that his question was a good one. If the Son is begotten of the Father, does that not mean the Father came first? And if the Father came first, was there not a stretch of reality with no Son in it? Arius thought the answer was obvious, and he thought the alternative was two gods. Christians who want to say why he was wrong have to do actual theology, and the church did, for sixty painful years. The second reason is that his answer has never gone away. Every group since that has honoured Jesus as the highest of creatures rather than worshipped him as God is walking ground Arius mapped. One fact worth carrying through everything that follows. In 325 the emperor Constantine ordered Arius’s books burned and made possession of them a capital offence, and the order was largely obeyed. What survives of his own writing would fit on a few pages, and almost every word of it reaches us because an opponent copied it out in the course of refuting it. His dates come to us the same way, at second hand. No source records the year of his death, and 336 is a reconstruction, though a firm one: the account of the death sits between the Synod of Tyre in 335 and Constantine’s own death in 337, and scholars have settled on the year between. The birth year is a modern estimate, worked backwards from the ancient notices that treat him as an old man when the trouble began, and every date in the first half of his life is a convention rather than a record.

(●) c. 256 AD: Born in Libya, in a year nobody troubled to write down. + Epiphanius, the bishop of Salamis in Cyprus who compiled a long catalogue of heresies about forty years after Arius died, says he was a Libyan by birth. That means the Greek-speaking coast west of Egypt, the region the Romans called Cyrenaica or the Pentapolis, whose churches looked to Alexandria the way a market town looks to the city. It is a plausible detail, and it is nearly all there is. Nothing else about the first fifty or sixty years survives: no parents, no schooling, no conversion story. The date "c. 256" is an inference rather than a record. The ancient notices treat him as already old when the controversy broke out around 318, one of them puts him past eighty when he died, and a letter Constantine sent him in 333 sneers at his wasted and emaciated body. Out of that, historians put his birth somewhere in the 250s and say so with the margin showing. There is one description of how he looked, and it comes from an enemy. Epiphanius pictures a very tall man with a downcast face, plainly dressed, soft-spoken and persuasive, and compares him to a serpent. That is a hostile portrait written decades later by a man who wanted his readers to shudder, and it should be read as one. What can be said with more confidence is that people found him convincing, which is the whole reason there is a story to tell.

(●) c. 306 AD: Ordained in a church bleeding from persecution, he was thrown out of it once before anyone had heard his doctrine. + Picture the problem the Egyptian church faced in the middle of Diocletian’s persecution, and picture it from a pew. Some clergy had handed over the Scriptures to be burned, or offered incense to the emperor’s image, to stay alive. They wanted their pulpits back as soon as the danger eased, and the congregations who had sat there and watched them do it wanted to know on what terms a man like that gets to break the bread again. Melitius, a bishop in the Thebaid, the stretch of upper Egypt around the old city of Thebes, took the hard line. While Peter of Alexandria was in hiding he went on ordaining his own clergy in other men’s dioceses, and out of that came a schism, a split in the church over discipline rather than doctrine, that outlasted everyone involved in it. Arius turns up inside that quarrel before he turns up in his own. Sozomen, a historian writing more than a century later, reports that he first took Melitius’s side and then left it, and that Peter ordained him a deacon. Peter also ruled that baptisms performed by Melitian clergy did not count, and Arius, who had walked away from the Melitians himself, attacked the ruling anyway. For that Peter expelled him. Then Peter died a martyr, his successor Achillas took Arius back, restored him as deacon, and in time made him a presbyter. A presbyter, from the Greek word for elder, is an ordained minister with charge of one congregation under the city’s bishop, and it is the word that "priest" has been worn down from. Epiphanius adds that the congregation given to Arius was the church called Baucalis, one of Alexandria’s parish churches. All of that comes from writers who were not there and who had already decided what they thought of him, so the details are soft and the dates are softer. Nothing fixes the diaconate, his years serving as a deacon, more closely than the span in which Peter held the see, the bishop’s chair at Alexandria, from 300 to 311. His presbyterate, the charge of Baucalis, is usually put around 313, under Achillas. The shape of the story is worth keeping even so. The man who would one day divide the church over the nature of the Son had already been excommunicated once, cut off from the church’s table and its fellowship, over a question about mercy and discipline, and had already been let back in.

(●) c. 318 AD: He contradicted his bishop in front of the clergy, and one sentence went across Egypt. + Alexander, by then the bishop of Alexandria, was doing what bishops do: instructing his clergy. The subject was the Trinity, the Christian confession that the Father, the Son and the Holy Spirit are one God and not three. Socrates Scholasticus, whose history is the fullest account of the outbreak, says Alexander was explaining its unity "with perhaps too philosophical minuteness," and that one of his presbyters, a man with a sharp head for logic, thought he heard something dangerous in it. What Arius thought he heard was Sabellianism. Sabellius, a teacher of the previous century, had said that Father, Son and Spirit are not three who are truly distinct but three costumes worn in turn by one actor, three ways the one God has appeared. The church had rejected that, because it makes the Son’s prayers to the Father a piece of theatre. Arius, hearing his bishop press the oneness so hard, pushed back the other way, and Socrates records the sentence: "If the Father begat the Son, he that was begotten had a beginning of existence: and from this it is evident, that there was a time when the Son was not. It therefore necessarily follows, that he had his substance from nothing." Read it slowly, because the whole crisis is in those three steps. Begotten means there was a begetting. A begetting is a beginning. Whatever begins was, before it began, nothing. It has the tidy feel of a proof, and that is exactly why it travelled. Socrates says the evil began at Alexandria and ran through Egypt, Libya and the upper Thebes and then through the rest of the provinces and cities, from a little spark to a large fire. Within a few years the argument was so far out of the churches and into the streets that Christianity was being mocked over it in the theatres.

(●) c. 321 AD: Nearly a hundred bishops of Egypt and Libya cut him off, so he took his case abroad, and set it to music. + Alexander tried persuasion first, and Sozomen says he sat as judge over two open debates between the parties in his own clergy before he moved. When he did move he moved hard. A synod, which is simply a council of bishops sitting together to settle a matter, brought nearly a hundred of them in from Egypt and Libya, and it condemned Arius along with the clergy who stood with him. Alexander then wrote round to the bishops of other cities, warning them not to receive the men he had just excommunicated. Arius wrote too. His letter to Eusebius, the bishop of Nicomedia and the most politically useful friend he had, is the one surviving document that went out under his name and nobody else’s, and it is a revealing piece of work: aggrieved, precise about what he actually holds, and shrewd about who else can be counted on. He signs off by calling Eusebius his fellow-Lucianist, which points both of them back to Lucian of Antioch, a scholar and martyr whose pupils turn up all over the Arian side of the fight. Then he did the thing that made him genuinely dangerous. He wrote the Thalia, the "Banquet," a defence of his position in loose popular verse. Athanasius, who quotes it in order to demolish it, notes with disgust that Arius had taken his metre not from any serious poet but from Sotades, whose name in the ancient world was a byword for the sort of verse recited at drinking parties. Philostorgius, a historian who was himself an Arian and had no reason to invent it, adds that Arius wrote songs for sailors, for millers, and for men walking the high roads, and fitted each to a tune that suited the work. Theology that a dock hand can whistle is a different kind of opponent from theology in a treatise, and everybody understood that.

(●) 325 AD: At Nicaea the bishops of the empire put one word into the creed that he could not sign. + Constantine, newly master of the whole empire and appalled that his most useful religion was tearing itself apart over what he called a subject improper for discussion, first sent Hosius of Cordova with a letter telling both men to stop. When that failed he summoned the bishops to Nicaea in Bithynia, paid their travel, fed them, and sat in the room. Socrates puts the number at more than three hundred, and the figure the church has remembered ever since is three hundred and eighteen. Some of them were still carrying the marks of the persecution that had ended barely a decade before. It was the first council to speak for the church across the whole empire, which is what the word ecumenical means. Arius was summoned and examined. What the council produced was a creed built like a fence, and the post it turns on is homoousios, "of the same substance": whatever the Father is, the Son is that, not a copy of it and not a lesser grade of it. Athanasius, then a young deacon in Alexander’s party, later explained why they reached for a word that is not in the Bible. Every scriptural phrase the bishops proposed, the Arian party proved willing to sign. When "power" and "image" and "always" were put forward, Athanasius says they were caught whispering and winking at each other, because a man is called the image of God too, and a caterpillar is called a power of God, so the words could be signed and meant in a smaller sense. The bishops chose a word that could not be smuggled through. Then they wrote the anathemas, the formal condemnations tacked on to the end of a creed, and they read almost like a transcript of Arius. The church anathematizes those who say "There was a time when he was not," and "He was not before he was begotten," and "He was made from that which did not exist." The sentence he had said out loud in front of his bishop is in there, nearly word for word. The bishops were quoting him back at himself. Socrates names five bishops who balked at homoousios, and in the end only two of them held out. Theonas of Marmarica and Secundus of Ptolemais would not sign, and they were deposed and sent into exile with Arius to Illyricum. As for the books, they were ordered burned, and possession of one was made a capital offence.

(●) c. 327 AD: He was recalled from exile on a confession of faith that never mentioned the point in dispute. + The rehabilitation began, as these things often do, in a sickroom. Socrates says Constantine’s sister Constantia kept a priest in her household who leaned Arian, and that on her deathbed she commended him to her brother. The man became a confidant, worked on the emperor by degrees, and told him what Constantine wanted to hear: that Arius had been misrepresented, and that he would sign the council’s faith if he were given the chance to say so. He was given the chance, and he took it. The statement Arius and his deacon Euzoius handed the emperor is a short, warm, entirely orthodox-sounding recital of the gospel, and it does not contain a single word about whether the Son is from the Father’s own substance or from nothing. Constantine, who had wanted an end to the noise rather than an answer to the question, was satisfied and sent him home to Alexandria with honour. Alexandria did not cooperate. Alexander had died in 328 and been succeeded by Athanasius, who refused to receive Arius on any terms and wrote to tell the emperor so, on the ground that a man once anathematized for denying the faith could not simply be waved back in. Constantine threatened him. Athanasius did not move. Everything that came at Athanasius afterwards flows out of that refusal. The charges arrived first, trumped up and lurid, accusing him of murder and of sabotage. Then came the Synod of Tyre in 335, which deposed him, meaning it stripped him of his office as bishop, and Constantine packed him off to Trier in Gaul. That was the first of his five exiles.

(●) 336 AD: He swore an oath at the palace, walked out into the city, and died the day before he was to receive communion. + With Athanasius out of the way, the bishops returning from Tyre stopped at Jerusalem and received Arius back into communion. Alexandria erupted at the news. Constantine summoned Arius to Constantinople, and there the emperor asked him directly whether he assented to the faith of Nicaea. Arius said yes, put it in writing, and, when Constantine made him confirm it, swore to it. Socrates passes on a story about that oath. Arius, it was said, had a paper of his own tucked under his arm while he swore, so that when he swore he believed what he had written, the words could be true of the paper against his ribs rather than of the creed he had just signed for the emperor. Socrates flags the story as hearsay and says that only the oath itself is documented, which is the right way to handle it. Alexander, the bishop of Constantinople, was ordered to give him communion the next day and could not bear it. Athanasius had the account from Macarius, a presbyter who was in the church with him, and reports the prayer: that if Arius were right, Alexander might not live to see the day, and that if the faith of the church were right, God would take Arius away rather than let the heresy appear to enter with him. What happened next is reported twice over, and it helps to know who the two reporters are before hearing it. One is Athanasius, an enemy, who had his account from Macarius, the presbyter standing in the church that morning. The other is Socrates, a historian working a hundred years later from documents and from the memory of the city. It was the Sabbath, a Saturday, with the communion set for the following day. Arius was walking through the middle of the city with a crowd of supporters around him when, near Constantine’s Forum, he was seized by a violent looseness of the bowels. He asked for a privy, and he died there of a massive haemorrhage. Socrates gives the clinical detail and adds that in his own day, a century on, people were still pointing out the spot. Athanasius tells it more briefly, in a phrase borrowed from what Scripture says of Judas, and he is careful to say why he is telling it at all: he had been asked whether Arius died in communion with the church, and he answers the question flatly, adding that the church was glad "not as exulting in his death (God forbid!)." Readers can weigh the theology of that as they like. Athanasius gives no street and no landmark, only the collapse, and Socrates supplies the place. What both of them are reporting is a sudden death in a public place, on a day when everybody in the city was watching.

What He Taught

(T1) God alone has no source, and that is what makes him God. + Everything in Arius runs from one conviction, and it is a conviction any Jew or Muslim would recognise and most Christians would say amen to. There is one God, he is not one item in a class of similar items, and the mark of his uniqueness is that he came from nowhere. Everything else that exists got its being from something else. The oak came out of the acorn and the acorn off an older oak, and you can follow that chain back as far as patience allows without ever reaching a link that put itself there. God is not on the chain at all. The technical word for this is unbegotten, or in older English translations ingenerate: not made, not derived, not caused, having no origin whatever. Arius treated it as the defining divine property, the one attribute that draws the line between God and absolutely everything else. And that is where his objection to Alexander came from. If the Son shares the Father’s own being and has no beginning either, then on Arius’s reckoning you have two beings who came from nowhere, two unoriginate beings, and two of those are two gods. He was not trying to demote Jesus for the fun of it. He was trying to keep the first commandment. Christian theology has never let go of the concern. "Hear, O Israel: The Lord our God, the Lord is one" (Deuteronomy 6:4) is not negotiable, and the Nicene bishops would have said so as loudly as he did. What they denied was his hidden assumption: that being begotten of the Father must work the way it works with creatures, as an event that happens at a moment to something that was not there before. Take that assumption out and the arithmetic changes. One being, eternally the Father of an eternal Son, is one God and not two.

(Q) "We acknowledge One God, alone Ingenerate, alone Everlasting, alone Unbegun, alone True, alone having Immortality, alone Wise, alone Good, alone Sovereign." + Source: Arius and his clergy, Letter to Alexander of Alexandria, in Athanasius, De Synodis 16 (Newman translation). The opening of the confession of faith Arius sent his bishop while the quarrel could still, in principle, have been settled inside Alexandria. Notice how much of it is warm and orthodox, and notice the word that does all the work: alone, repeated eight times before the Son is mentioned at all (T1).

(T2) The Son had a beginning, and before he was begotten he was not. + This is the famous half of Arius, the line the creed was written to shut out: there was when he was not. It follows from the first point almost mechanically. If only God is unbegotten, and the Son is begotten, then the Son is not in that sense God; and if he was begotten, there is a "before" on the other side of the begetting, and on that side he simply is not there. He was not working from logic alone. Two texts in particular gave him a real foothold, and it is worth being honest about how real. The first is a verse in Proverbs where Wisdom speaks, which the whole Greek-speaking church read in the Septuagint, the Greek translation of the Old Testament made a couple of centuries before Christ and used as Scripture by the apostles themselves. There the verse says that the Lord created Wisdom at the beginning of his ways. Christians had long identified that Wisdom with Christ. Read that way, Scripture appears to call the Son a created thing in so many words. The Hebrew verb underneath that Greek is less obliging, and the English Standard Version (ESV), which works from the Hebrew, renders it "The Lord possessed me at the beginning of his work, the first of his acts of old" (Proverbs 8:22). The Greek, though, was the text on the table in Alexandria, and Arius and his opponents alike were arguing from it. The second text is plainer still: "the Father is greater than I" (John 14:28), said by Jesus himself. So the church could not simply wave the argument away, and it did not. Athanasius gave the greater part of a whole book of his Orations to that one verse in Proverbs. The reply, in short, was that begetting in God is not an event on a calendar, because there was no calendar; that the Father is greater in the order of origin, as a source is to what flows from it, without being greater in nature; and that the opening of John draws the decisive line in the other place from where Arius drew it. "All things were made through him, and without him was not any thing made that was made" (John 1:3). Whoever made everything that was made is not himself among the things that were made.

(Q) "We are persecuted, because we say that the Son has a beginning, but that God is without beginning." + Source: Arius, Letter to Eusebius of Nicomedia, in Theodoret, Ecclesiastical History I.4 (Blomfield Jackson translation). Written after the Alexandrian synod had condemned him, to the best-connected friend he had. The other two documents that survive were signed jointly, by his fellow clergy or by his deacon; this one is his alone, and in it he states the charge against himself in his own words rather than letting his accusers do it (T2).

(T3) The Son is a creature, made out of nothing by the Father’s will, and not out of the Father’s own being. + A father and a son share a nature; whatever the father is, the son is. A sculptor and a statue do not; the statue is the sculptor’s work, however magnificent, and it is made of something else. Arius put the Son on the statue’s side of that line, and then spent a good deal of energy insisting that this was not the insult it sounds like. For he did not mean that the Son is a creature like other creatures. In his own language the Son is a "perfect creature," made before time and before the ages, and made unalterable. He is the one through whom God then made everything else, and he is the sole direct work of the Father’s own hand. The rest of us are made through the Son; the Son is made straight from God. Arius has him standing alone at the very top of everything that is not God, with nothing above him but the Father and nothing at all beside him. That word "unalterable" is worth stopping over, because Arius uses it here and his critics report him teaching the opposite, and both reports are fair. The difference is the difference between a man who has never once broken a promise and a man who could not break one if he tried. Of the first you can say quite truly that he does not change; of the second you are saying something else entirely. What Arius claims for the Son in this letter is the first kind. A creature’s nature is the sort of thing that can go one way or the other, and the Son, confirmed in the good, does not in fact go the other way. What he denies, and what the Thalia spells out, is the second kind, the Father’s kind, where being unchangeable is not an achievement but simply the sort of thing you are (T4). The letter to Alexander shows him fending off the misreadings he expected, and it is the best evidence that he thought of himself as a conservative rather than an innovator. He denies that the Son is an emission flowing out of the Father, as the Gnostic teacher Valentinus taught; denies that the Son is a portion broken off the Father, as the Manichees, the followers of Mani, taught; denies Sabellius’s single God wearing two names; denies the picture of one torch lit from another. Each of those was a live heresy with a name attached, and each of them, he thought, made God divisible or material. His alternative kept God untouched, and paid for it with the Son. Nicaea drew the line in the one place Arius had left open. Not "made", the creed says, but "begotten": begotten of the Father, that is, of the substance of the Father, of one substance with him. Two words, and the whole quarrel is in the gap between them.

(Q) "perfect creature of God, but not as one of the creatures; offspring, but not as one of things begotten" + Source: Arius and his clergy, Letter to Alexander of Alexandria, in Athanasius, De Synodis 16 (Newman translation). The heart of the confession, and the most carefully balanced sentence Arius wrote. He wants the Son high enough to be worth everything the church says about him and low enough to leave the Father alone at the top (T3).

(T4) The Son cannot fully know the Father, and could in principle have gone wrong. + There is a difference between knowing someone from the inside and knowing them very well from outside. A wife of forty years knows her husband as no biographer ever will, and no amount of study closes that gap, because the gap is not about the quantity of information. Arius put the Son on the biographer’s side. It follows from everything before it. If the Son is a creature, then like every creature he is finite, and a finite mind cannot take in an infinite one. The Thalia says so without flinching: God is unspeakable to his Son, the Son cannot investigate the Father, and, most startling of all, the Son does not know his own essence, meaning what he himself most deeply is. Whatever the Son knows and sees of God, he knows and sees "in His own measure," which is the same way we do, only better. The second half of this is harder still. A creature’s goodness is a creature’s achievement, so on Arius’s account the Son is by nature alterable, capable of changing, and remained good because he chose to. God, foreseeing that he would choose well, gave him the glory in advance. Alexander reports that when someone asked the Arian clergy point blank whether the Word could change as the devil had changed, they answered that he could, since being begotten he was susceptible of change. That is the moment the doctrine stops being an abstraction. A saviour who might have gone wrong is a saviour you have to hope about. The church’s answer was to deny the premise rather than soften the conclusion. "No one knows the Father except the Son and anyone to whom the Son chooses to reveal him" (Matthew 11:27) is not the language of a creature reporting at second hand, and "Jesus Christ is the same yesterday and today and forever" (Hebrews 13:8) is not the language of a nature that might have gone another way.

(Q) "To speak in brief, God is ineffable to His Son. For He is to Himself what He is, that is, unspeakable." + Source: Arius, Thalia, quoted in Athanasius, De Synodis 15 (Newman translation). Ineffable means beyond words, unable to be spoken. Athanasius reproduces this stretch of the Thalia continuously rather than in snatches, and it is generally reckoned the closest thing we have to Arius’s own text. A few lines earlier in the same passage stands the sentence that gives the whole system away: "Foreign from the Son in essence is the Father, for He is without beginning" (T4).

(Q) "We believe in one God the Father Almighty: and in the Lord Jesus Christ his Son, who was begotten of him before all ages, God the Word through whom all things were made." + Source: Arius and Euzoius, statement of faith presented to the Emperor Constantine, in Socrates Scholasticus, Ecclesiastical History I.26 (Zenos translation). The document that got him out of exile, and the reason the fight went on for another forty-five years after he was dead. Every clause of it is true. Not one clause of it says whether the Son is from the Father’s substance or from nothing, which was the only thing anyone wanted to know. Constantine read it and was satisfied. Athanasius read it and was not.

What the Church Made of Him

(†) The creed most Christians still recite was built to answer him, sentence by sentence. + Nothing focuses a church’s mind like discovering that it cannot say what it believes. Before Arius, Christians had prayed to Jesus, sung to him, baptised in his name and died rather than call Caesar Lord, and they had done all of it without an agreed technical account of how the Son stands to the Father. Arius asked for the account, and the church found it did not have one ready. What came out of Nicaea in 325 is short and it is aimed. "Of the substance of the Father" answers the claim that the Son was made from nothing. "True God from true God" answers the claim that he is God by courtesy. "Begotten, not made" answers the claim that begetting and making are the same act. Then the anathemas quote Arius almost word for word in order to shut the door: the church condemns anyone who says "There was a time when he was not," or "He was not before he was begotten," or "He was made from that which did not exist." The choice of homoousios, "of one substance," was expensive and the bishops knew it. It is not a biblical word, it had a shady history (the synod that deposed Paul of Samosata at Antioch in 268 had censured it, as Athanasius himself had to admit), and putting a philosophical term into a confession of faith looked to many like exactly the mistake Arius was accused of. They did it because the biblical words had stopped working. Athanasius says the Arians were prepared to sign every scriptural phrase on offer and mean something else by it, and that the bishops watched them nodding at each other while it happened. Sometimes plain speech requires a word from outside the text, and the test of such a word is whether it lets a text say what it was already saying. Half a century of argument later, the church at Constantinople in 381 kept the word and added the Spirit to the sentence, and that is the creed still read on Sundays.

(†) Athanasius spent his life on the question, and turned it from a puzzle about words into a question about being saved. + The deacon who stood at Alexander’s shoulder at Nicaea became bishop of Alexandria in 328 and was driven out of his city five times over the next forty-five years, spending something like seventeen of them in exile: in Gaul, in Rome, and three times in hiding in Egypt, mostly among the monks of the desert. For long stretches the imperial court and a majority of eastern bishops were against him. The Latin phrase Athanasius contra mundum, Athanasius against the world, is a later coinage, but it is not a bad summary of the middle of the fourth century. His decisive move was to shift the ground. The Arian case had been argued as a problem in logic and grammar about the word "begotten." Athanasius argued it as a problem about rescue. Only God can make creatures God’s own; a creature, however exalted, cannot bridge a gap it stands on the wrong side of; so if the Son is a creature, then either he did not save us or a creature did, and neither is what the church has been saying since the beginning. And there was a second argument, blunter and harder to answer. Christians worshipped Jesus. Pliny, a Roman governor writing to the emperor Trajan around 112, had already described them meeting before dawn to sing a hymn to Christ as to a god. Either that worship is idolatry, since "I am the Lord; that is my name; my glory I give to no other" (Isaiah 42:8), or the one worshipped is God. Arius’s position left no third door. The finishing was done by others. Basil of Caesarea, his brother Gregory of Nyssa and their friend Gregory of Nazianzus, the Cappadocians, supplied the vocabulary that let the church say one substance and three persons without saying either three gods or one God in three masks. When Athanasius died in 373 the outcome was still in doubt. Eight years later, at Constantinople, it was settled.

(†) Modern historians read him more carefully than his opponents did, and the man who comes back is a conservative. + For fifteen centuries Arius was mostly read through Athanasius, which is a little like learning about a defendant only from the prosecutor’s closing speech. Two books changed that for English readers: Rowan Williams’s Arius: Heresy and Tradition (1987) and R. P. C. Hanson’s The Search for the Christian Doctrine of God (1988), whose subtitle, "The Arian Controversy 318 to 381," makes the point that it was a search and not a rerun of something already known. Their picture is not a rehabilitation, and neither man thought Arius was right. It is a correction of the caricature. He was a churchman rather than a freethinker, working from Scripture and from the Alexandrian tradition he had inherited, using the same Greek philosophical vocabulary his opponents used, and honestly frightened that the alternative destroyed the oneness of God. The bishops who condemned him were not defending a settled formula against an intruder; they were being forced, by his question, to work out what they had always meant. That is a harder and more interesting story than heresy versus orthodoxy, and it is closer to what the documents show. It also comes with a warning label about the evidence, which any reader should keep in hand. Two letters and a creed survive that are unquestionably his. Everything else is a quotation inside a hostile work, and scholars weigh those quotations differently: the continuous extract in De Synodis 15 is usually treated as close to his words, the paraphrase in the Orations as Athanasius’s summary of what he thought Arius meant. Where the sources are one-sided, saying so is part of telling the truth.

(†) Where the gospel parts company with him: a Son who was made, a Son who might have failed, and worship handed to a creature. + Give him what he is owed first, because the objection is only worth answering at full strength. There is one God, and Arius would not let go of it. The Son truly is from the Father, truly obedient, truly sent. "The Father is greater than I" (John 14:28) is a real sentence in a real Gospel, and any account of Christ has to make room for it. Where the parting comes is not in his zeal for the one God but in the price he was willing to pay for it. - Made, or begotten. Arius’s Son is the first and highest thing God made. John puts him on the other side of that line: "All things were made through him, and without him was not any thing made that was made" (John 1:3). Paul says the same twice over, that "by him all things were created, in heaven and on earth, visible and invisible" (Colossians 1:16), and that "he is before all things, and in him all things hold together" (Colossians 1:17). A maker of everything made is not one of the things made. - Changeable, or the same. On Arius’s account the Son stayed good by choosing to, and might have chosen otherwise; his own followers said as much when they were asked. Scripture treats the Son’s constancy as the ground under everything else: "Jesus Christ is the same yesterday and today and forever" (Hebrews 13:8). A saviour who might have gone wrong is a saviour you can only hope about, and the New Testament does not speak that way about him. - Worship. This is the sharpest point, because it is about what Christians were already doing rather than what they theorised. Thomas, seeing the wounds, says to Jesus, "My Lord and my God!" (John 20:28), and is not corrected. John hears every creature in heaven and on earth saying "To him who sits on the throne and to the Lamb be blessing and honor and glory and might forever and ever!" (Revelation 5:13). If the Lamb is a creature, then the worship at the centre of the Christian faith breaks the first commandment. If he is not, Arius’s account collapses. - What is at stake. Athanasius’s argument still holds the weight. If only God can join creatures to God, then a created saviour is a bridge with one end resting on the wrong bank. The Christian claim is not that God sent his best creature to fetch us; it is that "the Word became flesh and dwelt among us" (John 1:14). Arius asked a question the church genuinely had to answer, and asked it more sharply than anyone before him. That is why the creed exists, and why he is remembered. The answer he gave leaves the Father alone on his throne, intact and untouchable, and leaves everyone else at a distance that only God could cross.
