Zuinglius's step was slow, but progressive. He did not come to the truth like Luther amid those tempests which compel the soul to seek a speedy shelter. He arrived at it by the peaceful influence of Scripture, whose power gradually gains upon the heart. Luther reached the wished-for shore across the billows of the boundless deep; Zuinglius, by allowing himself to glide along the stream. These are the two principal ways by which God leads men. Zuinglius was not fully converted to God and his gospel till the first period of his sojourn at Zurich; yet, in 1514 or 1515, at the moment when the strong man began to bend the knee to God, praying for the understanding of his Word, the rays of that pure light by which he was afterwards illumined, first began to gleam upon him. At this period, a poem of Erasmus, in which Jesus Christ was introduced addressing man as perishing by his own fault, made a powerful impression on Zuinglius. When alone in his study, he repeated the passage in which Jesus complains that all grace is not sought from him, though he is the source of all that is good. "ALL!" said Zuinglius, "ALL!" And this word was incessantly present to his mind. "Are there then creatures, saints, from whom we ought to ask assistance? No! Christ is our only treasure."[639] [639] Dass Christus unser armen seelen ein einziger Schatz sey. (Zw. Op. i, p. 398.) Zuinglius says in 1522 that he had read the poem of Erasmus eight or nine years before. Zuinglius did not confine his reading to Christian writings. One of the distinguishing characteristics of the sixteenth century is the profound study of the Greek and Roman authors. The poetry of Hesiod, Homer, Pindar, enraptured him, and he has left us commentaries, or characteristics, on the two last poets. It seemed to him that Pindar spoke of his gods in such sublime strains that he must have had some presentiment of the true God. He studied Cicero and Demosthenes thoroughly, and learned from them both the art of the orator and the duties of the citizen. He called Seneca a holy man. The Swiss mountaineer loved also to initiate himself in the mysteries of nature, through the writings of Pliny. Thucydides, Sallust, Livy, Cæsar, Suetonius, Plutarch, and Tacitus, taught him to know the world. He has been censured for his enthusiastic admiration of the great men of antiquity, and it is true that some of his observations on this subject cannot be defended. But if he honoured them so much, it was because he thought he saw in them not human virtues, but the influence of the Holy Spirit. The agency of God, far from confining itself to ancient times within the limits of Palestine, extended, according to him, to the whole world.[640] "Plato," said he, "has also drunk at the Divine source. And if the two Catos, if Camillus, if Scipio had not been truly religious, would they have been so magnanimous?"[641]
