Hilary threw himself heartily into it. He travelled, we know, extensively; so much so, that his letters from Gaul failed to reach him in the year 358. This was a serious matter. We have seen that the exiles from the West had derived great support from their flocks. Hilary’s own weight as a negotiator must have depended upon the general knowledge that he did not stand alone, but represented the public opinion of a great province. For this reason, as well as for his own peace of mind, it must have been a welcome relief to him to learn, when letters came at last, that his friends had not forgotten or deserted him; and he seized the opportunity of reply to send to the bishops of all the Gallic provinces and of Britain the circular letter which we call the De Synodis, translated in this volume. The Introduction to it, here given, makes it unnecessary to describe its contents. It may suffice to say that it is an able and well-written attempt to explain the Eastern position to Western theologians. He shews that the Eastern creeds, which had been composed since the Nicene, were susceptible of an orthodox meaning, and felicitously brings out their merits by contrast with the unmitigated heresy of the second creed of Sirmium, which he cites at full length. It must be admitted that there is a certain amount of special pleading; that his eyes are resolutely shut to any other aspect of the documents than that which he is commending to the attention of his readers in Gaul. And he is as boldly original in his xixrendering of history as of doctrine. He actually describes the Council of the Dedication, which confirmed the deposition of Athanasius and propounded a compromising creed, definitely intended to displace the Nicene, as an ‘assembly of the saints.’ The West, we know, cared little for Eastern disputes and formularies. There can have been no great risk that Hilary’s praise should revolt the minds of his friends, and as little hope that it would excite any enthusiasm among them. This description, and a good deal else in the De Synodis, was obviously meant to be read in the land where it was written.
When all possible allowance is made for his sympathy with the best men among the Asiatics, and for the hopefulness with which he might naturally regard his allies, it is still impossible to think that he was quite sincere in asserting that their object in compiling ambiguous creeds was the suppression of Sabellianism and not the rejection of the homoousion. Yet it was natural enough that he should write as he did, for the prospect must have seemed most attractive. If this open letter could convince the Eastern bishops that they were regarded in the West not with suspicion, as teachers of the inferiority of Christ, but with admiration, as steadfast upholders of His reality, a great step was made towards union. And if Hilary could persuade his brethren in Gaul that the imperfect terms in which the East was accustomed to express its faith in Christ were compatible with sound belief, an approach could be made from that side also. And in justice to Hilary we must bear in mind that he does not fall into the error of Liberius.
It was a serious fault for a Western bishop to abandon words which were, for him and for his Church, the recognised expression of the truth; it was a very different matter to argue that inadequate terms, in the mouth of those who were unhappily pledged to the use of them, might contain the saving Faith. This latter is the argument which Hilary uses. He urges the East to advance to the definiteness of the Nicene confession; he urges the West to welcome the first signs of such an advance, and meantime to recognise the truth that was half-concealed in their ambiguous documents. The attempt was a bold one, and met, as was inevitable, with severe criticism from the side of uncompromising orthodoxy, which we may for the moment leave unnoticed. What Athanasius thought of the treatise we do not know; it would be unsafe to conjecture that his own work, which bears the same title and was written in the following year, when the futility of the hope which had buoyed Hilary up had been demonstrated, was a silent criticism upon the De Synodisof the other. It is, at least, a success in itself, and was a step towards the ultimate victory of truth; we cannot say as much of Hilary’s effort, admirable though its intention was, and though it must have contributed something to the softening of asperities. But Alexandria and Gaul were distant, and while the one excited repugnance in the Emperor’s mind, the other had little influence with him.
The decision seemed to lie in the hands of Basil of Ancyra and his colleagues. The men who had the ear of Constantius, and had lately induced him to banish the Arians, must in consistency use their influence for the restoration of exiles who were suffering for their opposition to Arianism; and this influence, if only the West would heartily join with them, would be strong enough to secure even the restoration of Athanasius. Such thoughts were certainly present in the mind of Hilary when he painted so bright a picture of Eastern Councils, and represented Constantius as an innocent believer, once misguided but now returned to the Faith. From the Semiarian leaders, controlling the policy of Constantius, he expected peace for the Church, restoration of the exiles, the suppression of Arianism. And if to some extent he deceived himself, and was willing to believe and to persuade others that men’s faith and purpose differed from what in fact it was, we must remember that it was a time of passionate earnestness, when cool judgment concerning friend or foe was almost impossible for one who was involved in that great conflict concerning the Divinity of Christ.
