Within a few months of the battle Constantine had declared that Christianity should be tolerated, and within a year he had started an enormous building programme of churches, in a traditional (pagan) exercise of patronage that transformed the Christian communities. There is no doubt, therefore, that Constantine’s victory was associated with a programme of active support for the Christian churches, but was Constantine’s “conversion” quite as sudden and dramatic as the Christian commentators suggest? H. A. Drake argues that it was not.8 Constantine was, as we have suggested, a shrewd political operator. As he had observed earlier attempts to eradicate Christianity, he must have realized that they they were fruitless. They were simply reinforcing the very precedent, that of martyrdom, with which the harassed Christians already identified. If there was to be harmony in the empire, something more imaginative was required, perhaps a political volte-face as a result of which Christianity could be integrated into the state. It was a mark of Constantine’s political genius and flexibility that he realized it was better to utilize a religion that already had a well-established structure of authority as a prop to the imperial regime rather than exclude it as a hindrance. Drake argues that this idea of integrating rather than rejecting Christians may have grown in Constantine’s mind as the failure of the persecutions became obvious, and that he used the victory at the Milvian Bridge as a platform from which to launch his new policy.
The adoption of Christianity was not, however, to prove entirely straightforward. Constantine knew so little about Christianity that he immediately ran into difficulties. First, Christ was not a god of war. The Old Testament frequently involved God in the slaughter of his enemies, but the New Testament did not. Constantine would have to create a totally new conception of Christianity if he was to sustain the link between the Christian God and victory in war. Second, it was crucial for Constantine’s political survival that he did not break with the pagan cults that still claimed the allegiance of most of his subjects, yet Christianity emphatically rejected paganism; many Christian groups would never accept a relationship with a state still condoning paganism. Some very careful political manoeuvring was necessary if Constantine was to avoid offending either Christian or pagan. Finally, while Constantine might have hoped for a church that could be subservient to him, he found one racked with disputes and power struggles. This became even more apparent when he came to power in the east and confronted the maelstrom of conflict and rivalry among the Greek-speaking Christians.
Once he had announced his “conversion,” Constantine’s first task was formally to end the persecutions by ensuring toleration for Christians. Galerius’ successor in the eastern empire, Licinius, anxious to strengthen his own precarious position, made an alliance with Constantine in 313, and they jointly issued a proclamation in Milan, usually known as the Edict of Milan, that henceforth Christianity, and all other cults, would be tolerated throughout the empire. Any buildings damaged as a result of the persecutions of Christians would be restored.
With salutary and most upright reasoning, we resolved on adopting this policy, namely that we should consider that no one whatsoever should be denied freedom to devote himself either to the cult of the Christians or to such religion as he deems best suited for himself, so that the highest divinity, to whose worship we pay allegiance with free minds, may grant us in all things his wonted favour and benevolence.
So Constantine effectively brings the Christians back into the Roman community without jeopardizing the position of any other religious belief. A “highest divinity” is assumed, but the concept, as we have seen, could be as easily used in the pagan world as the Christian and offered no conflict with Constantine’s desire for political harmony. This edict deserves an honoured place in European history as the first proclamation of the right to freedom of worship, an idea implicit in Roman government but never stated so clearly as here.9
Three years after his victory at the Milvian Bridge, Constantine was honoured by a grand triumphal arch in the centre of Rome (it still stands by the Colosseum), supposedly erected by a decision of the Senate of Rome but clearly a further statement of his new policy. The arch is conventional in form and is notable for its use of reliefs removed from monuments to earlier emperors, Trajan, Hadrian and Marcus Aurelius. This may have been the result of a desire to get the arch finished before the tenth anniversary of Constantine’s accession to power, but it has also been suggested that Constantine wished to associate himself with “good” emperors, even though, of course, they had not been Christians. The imagery of the arch contains no suggestion of the influence of Christianity. There are, in fact, reliefs of Mars, Jupiter and Hercules, all traditional gods of war, and Constantine’s victory at the Milvian Bridge is associated with the power of the sun and the goddess Victory. The depiction of the battle itself shows no sign of the Christian visions or Christian symbols on the soldiers’ shields. Elsewhere on the arch Constantine is shown in traditional imperial roles, making a speech in the Roman Forum and handing out poor relief. On an inscription on the arch, Constantine’s victory is credited to the “instigation of the Divinity,” and bearing in mind that this was by now conventional pagan terminology, no one could have been offended by it.10
For committed Christians, the idea that their support might have been sought for purely political reasons would have been abhorrent. In so far as theirs was a religion requiring absolute dedication and the rejection of all other cults, conversion meant a complete change of lifestyle and the rejection of the conventional values and beliefs of Greco-Roman society. Constantine may not have been aware of this. As a traditional Roman, he had been brought up in a society where allegiance to several cults could be held simultaneously, as his own patronage of Hercules, Apollo and Sol Invictus shows. He seems to have assumed that Christianity would be the same and that any involvement he might have in Christian rituals would not be at the expense of earlier allegiances. This would explain why he continued to use the traditional imagery of the sun to support his authority. Constantine was still issuing coins bearing images of Sol Invictus as late as 320, and in the great bronze statue he later erected to himself in the Forum in Constantinople he was portrayed with the attributes of a sun-god, with rays emanating from his head.
One reason why this pagan association was so successful in maintaining the emperor’s status was that the sun was also used in Christian worship and symbolism. The resurrection was believed to have taken place on the day of the sun, the most important day of the week for Christian worship (as the English word “Sunday” still suggests). A third-century fresco from the Vatican Hill in Rome even shows Christ dressed as the sun-god in a chariot on his way to heaven. The Christian writer Lactantius, who was writing at this time, urged Christians to observe the sun as if it were heaven and a symbol of “the perfect majesty and might and splendour” of God. “It is likely,” concludes J. W. Liebeschuetz in his perceptive study of Constantine’s proclamations, Change and Continuity in Roman Religion, “that in the minds of many fringe Christians, Jesus and the sun were closely associated.”11 In the fifth century Pope Leo was to rebuke Christians at St. Peter’s for turning their backs on St. Peter’s tomb and standing on the front steps of the basilica to worship the rising sun.12 Remarkably, the main festival of Sol Invictus was the day of the winter solstice, December 25, adopted by Christians in the fourth century as the birthday of Christ. In short, the sun was a symbolic image through which Constantine could be presented effectively to both Christian and non-Christian audiences, thus maintaining his neutral position between opposing faiths. Constantine’s balancing act continued. Liebeschuetz suggests that imperial panegyrics, or at least those written in Latin, are, after 321, “written in terms of a neutral monotheism which would be acceptable to Christians and pagans alike.”13 Later in his reign Constantine authorized the city of Hispellum on the Flaminian Way in Umbria to build a temple “in magnificent style” to the cult of his family, another indication of his reluctance to abandon traditional worship.

However, despite his balanced policy towards both pagan and Christian, nothing can obscure the scale of the commitment Constantine showed to Christianity. He started with the granting of special favours to Christian clergy, in particular exemption from the heavy burden of holding civic office and taxation. Earlier emperors had granted exemptions to specific groups (doctors, teachers, athletes are among those recorded) but never, outside the special circumstances of Egypt, to clergy. The exemption was, in Constantine’s words, so that the clergy “shall not be drawn away by any deviation and sacrifice from the worship that is due to the divinity, but shall devote themselves without interference to their own laws . . . for it seems that, rendering the greatest possible service to the deity, they most benefit the state.”14 Here Constantine appears to be tying the Christian communities into the service of the state. He may have felt that only a powerful gesture such as tax exemption would succeed in allaying the distrust of Christians after so many decades of persecution by the state. However, he may not have foreseen the consequences. He appears to have been genuinely surprised at the number and diversity of communities calling themselves Christian, and soon after his victory he had to face the dilemma of whether to give patronage to all of these or to privilege some communities more than others. The issue arose first in north Africa. The provinces there, part of Maxentius’ territory, had surrendered to Constantine, who had acknowledged the bishop of Carthage, Caecilian, with imperial patronage, granting the clergy of his diocese exemptions from civic duties and taxation. Rival African bishops protested, claiming that Caecilian had no right to hold office, and thus receive imperial support, because he had been consecrated by a bishop who, during Diocletian’s first persecution, had surrendered the scriptures to the authorities to be burned—in other words, who had compromised with paganism. As Cyprian, the influential bishop of Carthage martyred in the previous century, had decreed, such a bishop had no legitimacy. The dissenting bishops went on to elect their own bishop of Carthage, Majorinus. Majorinus was succeeded by one Donatus in 313, and it is as the Donatists that the dissenters are remembered.
Writing to an official on the matter, Constantine expressed his fear that his own position as the ruler favoured by God would be jeopardized by these internal squabbles. He wrote: “I consider it absolutely contrary to the divine law that we should overlook such quarrels and contentions . . . whereby the Highest Divinity may perhaps be roused not only against the human race but also against myself, to whose care he has by his celestial will committed the government of all earthly things.”15 Reading between the lines, one might assume that Constantine’s real concern was that his policy of using the Christian churches as a stabilizing force for his regime was unravelling as their dissensions became increasingly apparent. He referred the dispute to two successive councils of bishops, one in Rome, the other in Gaul. Neither supported the Donatists, and in 316 Constantine withdrew his patronage from them. The evidence suggests that at first he had no clear preference for either group but that with time he became increasingly irritated by the rigid stance of the Donatists, who were clearly reluctant to compromise with the state and accept its authority.16 Constantine could hardly have foreseen the momentous consequences of his decision for the western empire. By isolating the Donatists, who made up the vast majority of Christians in north Africa, he helped to define in the western Christian communities that were left what was to become the Roman Catholic Church.
Whatever his religious concerns, Constantine’s major preoccupations remained military ones. Between 313 and 315 he campaigned with further success along the northern borders of the empire, but he was also set on further expansion of his power within. He remained co-emperor with Licinius, his fellow signatory of the Edict of Milan. Licinius had married Constantine’s half-sister, Constantia, and the two emperors appeared on coins together. However, both were ambitious men. In 316 they fell out, and Constantine forced Licinius to cede his European provinces, although he allowed him to remain as Augustus of his remaining eastern provinces. The final settlement came in 324 when Constantine won two major victories over Licinius and forced him to abdicate. Licinius was executed in 325 and his son Licinius II, who had been appointed a Caesar in 317, was killed a year later. Constantine was supreme within the empire.
The eastern empire with its long and rich cultural history was very different from the provinces of western Europe. It was also much more heavily Christianized, and a tradition of intense debate over doctrine was more deeply embedded than it had been, or ever became, in the west. The bishops of the great sees lived in continuous rivalry with each other. Constantine was shocked by what he found. Eusebius wrote: “The bishop of one city was attacking the bishop of another . . . populations were rising up against each other, and were all but coming to physical blows, so that desperate men, out of their minds, were committing sacrilegious acts, even daring to insult the images of the emperors.” Addressing a group of bishops some years later, Constantine vented his own exasperation at their squabbles: “Even the barbarians now through me, the true servant of God [sic], know God and have learned to reverence him while you [the bishops] do nothing but that which encourages discord and hatred and, to speak frankly, which leads to the destruction of the human race.”17 In short, his political position was threatened by the endemic political and doctrinal disunity of the Christian Greeks. Almost immediately he was confronted by a major dispute between the bishop of the important see of Alexandria, Alexander, and a presbyter in the diocese called Arius. It concerned the central problem of Christian doctrine, the relationship between God the Father and Jesus Christ the Son. The dispute had erupted dramatically when Arius interrupted one of Alexander’s sermons and Alexander, supported by other local bishops, had him excommunicated.
Few areas of church history have been so completely rewritten in the past twenty years as the “Arian controversy.”18 Traditionally church historians have suggested that an “orthodox” understanding, which accepted Jesus the Son as divine and fully part of the Godhead, was already in place by the 320s and that Arius challenged this “orthodoxy” with his claim that Jesus had been created as “Son,” thus distinct from a pre-existing God and subordinate to him as Father. This tradition relied heavily on the main contemporary source for Arianism, the polemical anti-Arian writings of Athanasius, bishop of Alexandria from 328 to 373. In these Arius and all those who failed to accept the “orthodox” position were grouped together and excoriated. Later historians drew heavily on Athanasius. H. M. Gwatkin, for instance, writing in 1882, condemned the Arians with this trenchant judgment based on Athanasius’ work: “On the one side their doctrine was a mass of presumptuous theorising, supported by alternate scraps of obsolete traditionalism and uncritical textmongering, on the other it was a lifeless system of unspiritual pride and hard unlovingness.” 19 Recently, however, historians have begun to decode Arianism. They have found that the movement Athanasius dubbed “Arian” was much broader and more complex than Athanasius had suggested and had a great deal of scriptural and theological backing.
To see the strength of the Arian position and why Arianism proved so difficult to eradicate from the Christian tradition, we might begin with some excerpts from the Gospels.20 Many passages suggest that Jesus himself saw God as somehow distinct from himself. Take, for instance, Mark 10:18, where Jesus says, “Why do you call me good? No one is good but God alone.” Again, in his agony at Gethsemene (Matthew 26:39), Jesus calls on God. “ ‘My father,’ he said, ‘if it is possible, let this cup pass me by. Nevertheless, let it be as you, not I, would have it.’ ” In John 17:3 Jesus prayed, “And eternal life is this: to know you, the only True God and Jesus Christ whom you have sent” (that is, knowledge of God is distinguished by the “and” from knowledge of Jesus Christ). Similar passages are to be found in Paul’s Epistles. The last verse of the Epistle to the Romans reads: “. . . it is all part of the way the eternal God wants things to be. He alone [sic] is wisdom; give glory therefore to him through [sic]
Jesus Christ for ever and ever.” The author of Hebrews (5:8), writing some time before A.D. 70, states, “Although he was the Son he learned to obey through suffering; but having been made perfect [the implication being that at some stage he was less than perfect], he became for all who obey him the source of eternal salvation and was acclaimed by God with the title of the High Priest of Melchizedek.” Then there is the verse from Proverbs (8:22) in which Wisdom, often identified by Christian exegetes with Christ, proclaims that “Yahweh created me when his purpose first unfolded, before the oldest of his works,” in other words, Christ, if identified with Wisdom, was a distinct creation. Drawing on such passages and ignoring those that were not so favourable to their interpretations, the Arians urged that Jesus was in some way distinct from and subordinate to God his Father, and perhaps essentially different in nature. Arian writings repeatedly return to the scriptures, in particular the Synoptic Gospels, for support.
