‘Whether a fresh title stood before the later hymns, which clearly belong to another, we cannot say; the collection is too short for this to be probable. It is obvious that, if we have in this manuscript the remains of a hymn-book for actual use, it was, like ours, a compilation; brief as it was, it may have been as large as the cumbrous shape of ancient volumes would allow to be cheaply multiplied and conveniently used. Many popular treatises, as for instance some by Tertullian and Cyprian, were quite as short. Who the compiler may have been must remain unknown. We must attach some importance to the evidence of the manuscript which has restored to us the De Mysteries and the Pilgrimage of Silvia; and we may reasonably suppose that this collection was made in the time, and even with the sanction, of Hilary, though we cannot accept him as the author of any of the three hymns which remain.
The spurious letter to his imaginary daughter Abra was apparently written with the ingenious purpose of fathering upon Hilary the morning hymn, Lucis Largitor splendide. This is a hymn of considerable beauty, in the same metre as the genuine Ambrosian hymns. But there is this essential difference, that while in the latter the rules of classical versification as regards the length of syllables are scrupulously followed, in the former these rules are ignored, and rhythm takes the place of quantity. This is a sufficient proof that the hymn is of a later date than Ambrose, and, a fortiori, than Hilary. There remains the so-called evening hymn, which has been supposed to be the companion to the last. This, again, is alphabetical, and contains in twenty-three stanzas a confession of sin, an appeal to Christ and an assertion of orthodoxy. The rules of metre are neglected in favour of an uncouth attempt at rhythm. Latin appears to have been a dead language to the writer, who adorns his lines with little pieces of pagan mythology, and whose taste is indicated by his description of heretics as ‘barking Sabellius and grunting Simon.’ The hymn is probably the work of some bombastic monk, perhaps of the time of Charles the Great; unlike the other four, it cannot possibly date from Hilary’s generation.
Omitting certain fragments of treatises of which Hilary may, or may not, have been the author, we now come to his attack upon Auxentius of Milan, and to the last of his complete works. Dionysius of Milan had been, as we saw, a sufferer in the same cause as Hilary. But he had been still more hardly treated; he had not only been exiled, but his place had been taken by Auxentius, an Eastern Arian of the school favoured by Constantius. Dionysius died in exile, and Auxentius remained in undisputed possession of the see. He must have been a man of considerable ability; perhaps, as we have mentioned, he was the creator of the so-called Ambrosian ritual, and certainly he was the leader of the Arian party in Italy and the further West. The very fact that Constantius and his advisers chose him for so great a post as the bishopric of Milan proves that they had confidence in him. He justified their trust, holding his own without apparent difficulty at Milan and working successfully in the cause of compromise at Ariminum and elsewhere. Athanasius mentions him often and bitterly as a leader of the heretics; and he must be ranked with Ursacius and Valens as one of the most unscrupulous of his party. While Constantius reigned Auxentius was, of course, safe from attack. But at the end of the year 364 Hilary thought that the opportunity was come. Since his last entry into the conflict Julian and his successor Jovian had died, and Valentinian had for some months been Emperor. He had just divided the Roman Empire with his brother Valens, himself choosing the Western half with Milan for his capital, while he gave Constantinople and the East to Valens. The latter was a man of small abilities, unworthy to reign, and a convinced Arian; Valentinian, with many faults, was a strong ruler, and favoured the cause of orthodoxy. But he was, before all else, a soldier and a statesman; his orthodoxy was, perhaps, a mere acquiescence in the predominant belief among his subjects, and it had, in any case, much less influence over his conduct than had Arianism over that of Valens. It must have seemed to Hilary and to Eusebius of Vercelli that there was danger to the Church in the possession by Auxentius of so commanding a position as that of bishop of Milan, with constant access to the Emperor’s ear; and especially now that the Emperor was new to his work and had no knowledge, perhaps no strong convictions, concerning the points at issue. As far as they could judge, their success or failure in displacing Auxentius would influence the fortunes of the Church for a generation at least. It would, therefore, be unjust to accuse Hilary as a mere busy-body. He interfered, it is true, outside his own province, but it was at a serious crisis; and his knowledge of the Western Church must have assured him that, if he did not act, the necessary protest would probably remain unmade.
Hilary, then, in company with his any Eusebius, hastened to Milan in order to influence the mind of Valentinian against Auxentius, and to waken the dormant orthodoxy of the Milanese Church. For there seems to have been little local opposition to the Arian bishop: no organized congregation of Catholics in the city rejected his communion. On the other hand, there was no militant Arianism; the worship conducted by Auxentius could excite no scruples, and in his teaching he would certainly avoid the points of difference. He and his school had no desire to persecute orthodoxy because it was orthodox. From their point of view, the Faith had been settled in such a way that their own position was unassailable, and all they wished was to live and to let live. And we must remember that the Council of Rimini, disgraceful as the manner was in which its decision had been reached, was still the rule of the Faith for the Western Church. Hilary and Eusebius had induced a multitude of bishops, amid the applause of their flocks, to recant; but private expressions of opinion, however numerous, could not erase the definitions of Rimini from the records of the Church. It was not till the year 369 that a Council at Rome expunged them. The first object of the allies was to excite opposition to the Arian, and in this they had some success. Auxentius, in his petition to the Emperor, which we possess, asserts that they stirred up certain of the laity, who had been in communion neither with himself nor with his predecessors, to call him a heretic.
