In France it was destined soon to excite similar tempests. It had already troubled the Church. It no longer, as before, sheltered itself beneath the shades of night to propagate its doctrines. It erected, by the side of the Catholic pulpit, another pulpit, from which its dogmas were defended by its disciples; it led its partisans at court, among the clergy, in the universities and in the parliaments. Calvin's book, _de Clementia_, gained him a large number of proselytes: his disciples had an austere air, downcast eyes, pale faces, emaciated cheeks--all the signs of labor and sufferings. They mingled little with the world, avoided female conversation, the court, and shows; the Bible was their book of predilection; they spoke, like the Saviour, in apologues. They were termed Christians of the primitive Church. To resemble these, they only needed the very essence of Christianity; namely, faith, hope, and charity. To be convinced that their symbol was as diversified as their faces, it was only necessary to hear them speak; some taught the sleep of the soul, after this life, till the day of the last judgment; others, the necessity of a second baptism. Among them there were Lutherans, who believed in the real presence, and Zwinglians, who rejected it; apostles of free-will, and defenders of fatalism; Melanchthonians, who admitted an ecclesiastical hierarchy; Carlstadians, who maintained that every Christian is a priest; realists, chained to the letter; idealists, who bent the letter to the thought; rationalists, who rejected every mystery; mystics, who lost themselves in the clouds; and Antitrinitarians, who, like Servetus, admitted but two persons in God. These doctors all carried with them the same book--the Bible. Servetus,[43] a Spanish physician, had left his own country, and established himself, in 1531, at Hagenau, where he had published different treatises against the Trinity. He had disputed at Basel with Oecolampadius, some time before this renegade from the Lutheran faith "was strangled by the devil," if we are to believe the account given by Doctor Martin Luther. Servetus boasted that he triumphed over the theologian. Having left Basel in 1532, and crossed the Rhine, he came to hurl a solemn defiance at Calvin; the gauntlet was taken up by the _cure_ of Pont l'Eveque, the place of combat indicated, the day for the tournament named, but at the appointed hour "the heart of this unhappy wretch failed," says Beza, "who having agreed to dispute, did not dare appear." Calvin, on his part--in his refutations of the errors of Servetus, published in 1554--boasts of having in vain offered the Spanish physician remedies suitable to cure his malady. Servetus pretends that his adversary was laying snares for him, which he had the good-fortune to avoid. At a later period he forgot his part, and came to throw himself into the ambuscade of his enemy.
