These, after all, are but petty flaws in so great a work. Not only as a thinker, but as a pioneer of thought, whose treasures have enriched, often unrecognised, the pages of Ambrose and Augustine and all later theologians, he deserves our reverence. Not without reason was he ranked, within a generation of his death, with Cyprian and Ambrose, as one of the three chief glories of Western Christendom Orosius, Apol. 1.. Jerome and Augustine mention him frequently and with honour. This is not the place to summarise or discuss the contents of his works; but the reader cannot fail to recognise their great and varied value, the completeness of his refutation of current heresies, the convincing character of his presentation of the truth, and the originality, restrained always by scrupulous reverence as well as by intellectual caution, of his additions to the speculative development of the Faith. We recognise also the tenacity with which, encumbered as he was with the double task of simultaneously refuting Arianism and working out his own thoughts, he has adhered to the main issues. He never wanders into details, but keeps steadfastly to his course. He refrains, for instance, from all consideration of the results which Arianism might produce upon the superstructure of the Faith and upon the conduct of Christians; they are undermining the foundations, and he never forgets that it is these which he has undertaken to strengthen and defend. Our confidence in him as a guide is increased by the eminently businesslike use which he makes of his higher qualities. This is obvious in the smallest details, as, for instance, in his judicious abstinence, which will be considered in the next chapter, from the use of technical terms of theology, when their employment would have made his task easier, and might even, to superficial minds, have enhanced his reputation. We see it also in the talent which he shews in the device of watchwords, which serve both to enliven his pages and to guide the reader through their argument. Such is the frequent antithesis of the orthodox unitas with the heretical unio, the latter a harmless word in itself and used by Tertullian indifferently with the former, but seized by the quick intelligence of Hilary to serve this special end E.g. iv. 42, fin.; such also, the frequent ‘Not two Gods but One E.g. i. 17.,’ and the more obvious contrast between the Catholic unum and the Arian unus. Thus, in excellence of literary workmanship, in sustained cogency and steady progress of argument, in the full use made of rare gifts of intellect and heart, we must recognise that Hilary has brought his great undertaking to a successful issue; that the voyage beset with many perils, to use his favourite illustration, has safely ended in the haven of Truth and Faith.
