About the year 350 Hilary was consecrated Bishop of Poitiers. So we may infer from his own words that he had been a good while regenerate, and for some little time a bishop, on the eve of his exile in 356 A.D. Whether, like Ambrose, he was raised directly from lay life to the Episcopate cannot be known. It is at least possible that this was the case. His position as a bishop was one of great importance, and, as it must have seemed, free from special difficulties. There was a wide difference between the Church organisation of the Latin-speaking provinces of the Empire (with the exception of Central and Southern Italy and of Africa, in each of which a multitude of insignificant sees were dependent upon the autocracy of Rome and Carthage respectively) and that of the Greek-speaking provinces of the East. In the former there was a mere handful of dioceses, of huge geographical extent; in the latter every town, at least in the more civilised parts, had its bishop. The Western bishops were inevitably isolated from one another, and could exercise none of that constant surveillance over each other’s orthodoxy which was, for evil as well as for good, so marked a feature of the Church life of the East. And the very greatness of their position gave them stability. The equipoise of power was too perfect, the hands in which it was vested too few, the men themselves, probably, too statesmanlike, for the Western Church to be infected with that nervous agitation which possessed the shifting multitudes of Eastern prelates, and made them suspicious and loquacious and disastrously eager for compromise. It was, in fact, the custom of the West to take the orthodoxy of its bishops for granted, and an external impulse was necessary before they could be overthrown. The two great sees with which Hilary was in immediate relation were those of Arles and Milan, and both were in Arian hands. But it needed the direct incitation of a hostile Emperor to set Saturninus against Hilary; and it was in vain that Hilary, in the floodtide of orthodox revival in the West, attacked Auxentius.
The orthodox Emperor upheld the Arian, who survived Hilary by eight years and died in possession of his see. But this great and secure position of the Western bishop had its drawbacks. Hilary was conscious of its greatness and strove to be worthy of it; but it was a greatness of responsibility to which neither he, nor any other man, could be equal. For in his eyes the bishop was still, as he had been in the little Churches of the past, and still might be in quiet places of the East or South, the sole priest, sacerdos, of his flock. In his exile he reminds the Emperor that he is still distributing the communion through his presbyters to the Church. This survival can have had none but evil results. It put both bishop and clergy in a false position. The latter were degraded by the denial to them of a definite status and rights of their own. Authority without influence and information in lieu of knowledge was all for which the former could hope. And this lack of any organised means of influencing a wide-spread flock—such a diocese as that of Poitiers must have been several times as large as a rural diocese of England—prevented its bishop from creating any strong public opinion within it, unless he were an evangelist with the gifts of a Martin of Tours. It was impossible for him to excite in so unwieldy a district any popular enthusiasm or devotion to himself. Unlike an Athanasius, he could be deported into exile at the Emperor’s will with as little commotion as the bishop of some petty half-Greek town in Asia Minor.
During the first years of Hilary’s episcopate there was civil turmoil in Gaul, but the Church was at peace. While the Eastern ruler Constantius favoured the Arians, partly misled by unprincipled advisers and partly guided by an unwise, though honest, desire for compromise in the interests of peace, his brother Constans, who reigned in the West, upheld the Catholic cause, to which the immense majority of his clergy and people was attached. He was slain in January, 350, by the usurper Magnentius, who, with whatever motives, took the same side. It was certainly that which would best conciliate his own subjects; but he went further, and attempted to strengthen his precarious throne against the impending attack of Constantius by negotiations with the discontented Nicene Christians of the East. He tried to win over Athanasius, who was, however, too wise to listen; and, in any case, he gained nothing by tampering with the subjects of Constantius. Constantius defeated Magnentius, pursued him, and finally slew him on the 11th August, 353, and was then undisputed master not only of the East but of the West, which he proceeded to bring into ecclesiastical conformity, as far as he could, with his former dominions.
The general history of Arianism and the tendencies of Christian thought at this time have been so fully and admirably delineated in the introduction to the translation of St. Athanasius in this series, that it would be superfluous and presumptuous to go over the same ground. It must suffice to say that Constantius was animated with a strong personal hatred against Athanasius, and that the prelates at his court seem to have found their chief employment in intrigues for the expulsion of bishops, whose seats might be filled by friends of their own. Athanasius was a formidable antagonist, from his strong position in Alexandria, even to an Emperor; and Constantius was attempting to weaken him by creating an impression that he was unworthy of the high esteem in which he was held. Even in the East, as yet, the Nicene doctrine was not avowedly rejected; still less could the doctrinal issue be raised in Gaul, where the truths stated in the Nicene Creed were regarded as so obvious that the Creed itself had excited little interest or attention.
Hilary at this time had never heard it, though nearly thirty years had passed since the Council decreed it. But there were personal charges against Athanasius, of which he has himself given us a full and interesting account, which had done him, and were to do him, serious injury. They had been disproved publicly and completely more than once, and with great solemnity and apparent finality ten years before this, at Sardica in 343 A.D. But in a distant province, aided by the application of sufficient pressure, they might serve their turn, and if the Emperor could obtain his enemy’s condemnation, and that in a region whose theological sympathies were notoriously on his side, a great step would be gained towards his expulsion from Egypt. No time was lost. In October, 353, a Council was called at Arles to consider the charges. It suited Constantius’ purpose well that Saturninus of Arles, bishop of the most important see in Gaul, and the natural president, was both a courtier and an Arian. He did his work well. The assembled bishops believed, or were induced to profess that they believed, that the charges against Athanasius were not made in the interests of his theological opponents, and that the Emperor’s account of them was true. The decision, condemning the accused, was almost unanimous.
Even the representative of Liberius of Rome consented, to be disavowed on his return; and only one bishop, Paulinus of Treves, suffered exile for resistance. He may have been the only advocate for Athanasius, or Constantius may have thought that one example would suffice to terrify the episcopate of Gaul into submission. It is impossible to say whether Hilary was present at the Council or no. It is not probable that he was absent: and his ignorance, even later, on important points in the dispute shows that he may xiwell have given an honest verdict against Athanasius. The new ruler’s word had been given that he was guilty; nothing can yet have been known against Constantius and much must have been hoped from him. It was only natural that he should obtain the desired decision. Two years followed, during which the Emperor was too busy with warfare on the frontiers of Gaul to proceed further in the matter of Athanasius. But in the Autumn of 355 he summoned a Council at Milan, a city whose influence over Gaul was so great that it might almost be called the ecclesiastical capital of that country. Here again strong pressure was used, and the verdict given as Constantius desired. Hilary was not present at this Council; he was by this time aware of the motives of Constantius and the courtier bishops, and would certainly have shared in the opposition offered, and probably in the exile inflicted upon three of the leaders in it. These were Dionysius of Milan, who disappears from history, his place being taken by Hilary’s future enemy, Auxentius, and Eusebius of Vercelli and Lucifer of Cagliari, both of whom were to make their mark in the future.
