For such independence of thought he could find precedent in Alexandrian theology, of which he was obviously a careful student and, in his free use of his own judgment upon it, a true disciple. When he was drawn into the Arian controversy and studied its literature, his thoughts to some extent were modified; but he never ceases to leave upon his reader the impression of an Oriental isolated in the West. From the Christian Platonists of Alexandria Dr. Bigg’s Bampton Lectures upon them are full of hints for the student of Hilary. come his most characteristic thoughts. They have passed on, for instance, from Philo to him the sense of the importance of the revelation contained in the divine name He that is. His peculiar doctrine of the impassibility of the incarnate Christ is derived, more probably directly than indirectly, from Clement of Alexandria. But it is to Origen that Hilary stands in the closest and most constant relations, now as a pupil, now as a critic. In fact, as we shall see, no small portion of the Homilies on the Psalms, towards the end of the work, is devoted to the controverting of opinions expressed by Origen; and by an omission which is itself a criticism he completely ignores one of that writer’s most important contributions to Christian thought, the mystical interpretation of the Song of Songs. It is true that Jerome Vir. Ill. 100. knew of a commentary on that Book which was doubtfully attributed to Hilary; but if Hilary had once accepted such an exegesis he could not possibly have failed to use it on some of the numerous occasions when it must have suggested itself in the course of his writing, for it is not his habit to allow a thought to drop out of his mind; his characteristic ideas recur again and again. In some cases we can actually watch the growth of Hilary’s mind as it emancipates itself from Origen’s influence; as, for instance, in his psychology. He begins (Comm. in Matt. v. 8) by holding, with Origen and Tertullian, that the soul is corporeal; in later life he states expressly that this is not the case E.g. Tract. in Ps. cxxix. 4 f.. Yet what Hilary accepted from Origen is far more important than what he rejected. His strong sense of the dignity of man, of the freedom of the will, his philosophical belief in the inseparable connection of name and thing, the thought of the Incarnation as primarily an obscuring of the Divine glory E.g. Trin. ix. 6., are some of the lessons which Origen has taught him. But, above all, it is to him that he owes his rudimentary doctrine concerning the Holy Spirit. Hilary says nothing inconsistent with the truth as it was soon to be universally recognised; but his caution in declining to accept, or at least to state, the general belief of Western Christendom that the Holy Spirit, since Christians are baptized in His Name as well as in that of Father and Son, is God in the same sense as They, is evidence both of his independence of the opinion around him and of his dependence on Origen. Of similar dependence on any other writer or school there is no trace. He knew Tertullian well, and there is some evidence that he knew Hippolytus and Novatian, but his thought was not moulded by theirs; and when, in the maturity of his powers, he became a fellow-combatant with Athanasius and the precursors of the great Cappadocians, his borrowing is not that of a disciple but of an equal.
