ZUINGLIUS (Ulricus), an able and zealous reformer, who laid the foundation of a separation from Rome in Switzerland, at the same time that Luther did the like in Saxony, was born at Wildhausen in 1487. While he officiated as preacher at Zurich, a Franciscan sent by Leo X. came to publish indulgences there; against which Zuinglius, after the example of Luther, declaimed powerfully. In the course of this opposition he started a new doctrine, which he called Evangelical Truth; and from the beginning of 1519 to 1523, he preached not only against indulgences, but against other articles of the Romish church. But though Zuinglius made no less progress than Luther, he yet conducted himself with more moderation and prudence; and wishing to have the concurrence of the civil powers, procured two assemblies to be called at Zurich: by the first, he was authorized to proceed as he had begun; and by the second, the outward worship and ceremonies of the church of Rome were abolished. During these transactions, Zuinglius published several books in defence of his doctrines; but treating of the eucharist, and prescribing a form of celebrating the Lord's supper, different from Luther, he was involved in violent disputes with the rest of his reforming brethren. The remainder of the Swiss cantons disallowing the proceedings of that of Zurich, other assemblies were called, and things tending to tumult, both sides had recourse to arms; when Zuinglius, who began as a preacher, died in arms as a soldier, in 1531. His works amount to four vols folio: his doctrines were afterward spread, with some alterations, by Calvin, Beza, and others, whose followers were called Calvinists, while the disciples of Zuinglius retained the name of Sacramentarians.
