This was the deliberate purpose of Hilary, and he had certainly counted its cost in im- mediate popularity and success. For though, as we have seen, the work did produce, as it deserved, a considerable effect at the time of its publication, it has remained ever since, in spite of all its merits, in a certain obscurity. There can be no doubt that this is largely due xxxv to the Mezentian union with such a document as Arius’ Epistle to Alexander of the decisively important section of the De Trinitate. The books in which that Epistle is controverted were those of vital interest for the age; and the method which Hilary’s plan constrained him to adopt was such as to invite younger theologians to compete with him. Future generations could not be satisfied with his presentation of the case. And again, his plan of refuting the Arian document point by point88, contrasting as it does with the free course of his thought in the earlier and later books, tends to repel the reader. The fourth book proves from certain texts that the Son is God; the fifth from the same texts that He is true God. Hence this part of the treatise is pervaded by a certain monotony; a cumulative impression is produced by our being led forward again and again along successive lines of argument to the same point, beyond which we make no progress till the last proof is stated. The work is admirably and convincingly done, but we are glad to hear the last of the Epistle of Arius to Alexander, and accompany Hilary in a less embarrassed enquiry. Yet the whole work has defects of its own. It is burdened with much repetition; subjects, especially, which have been treated in books ii. and iii. are discussed again at great length in later books89. The frequent stress laid upon the infinity of God, the limitations of human speech and knowledge, the consequent incompleteness of the argument from analogy, the humility necessary when dealing with infinities apparently opposed90, though it adds to the solemnity of the writer’s tone and was doubtless necessary when the work was published in parts, becomes somewhat tedious in the course of a continuous reading. And something must here be said of the peculiarities of style. We saw that in places, as for instance in the beginning of the De Trinitate, Hilary can rise to a singularly lofty eloquence. This eloquence is not merely the unstudied utterance of an earnest faith, but the expression given to it by one whom natural talent and careful training had made a master of literary form. Yet, since his training was that of an age whose standard of taste was far from classical purity, much that must have seemed to him and to his contemporaries to be admirably effective can excite no admiration now. He prays, at the end of the first book, that his diction may be worthy of his theme, and doubtless his effort was as sincere as his prayer. Had there been less effort, there would certainly, in the judgment of a modern reader, have been more success. But he could not foresee the future, and ingenious affectations such as occur at the end of book 88 v. 6. 89 E.g. bk. iii. is largely reproduced in ix.; ii. 9 f. = xi. 46 f. 90 E.g. i. 19, ii. 2, iii. 1, iv. 2, viii. 53, xi. 46 f. 51 The Life and Writings of St. Hilary of Poitiers.
