Calvin argued that only practices explicitly taught in Scripture could be used in worship. For this reason, churches influenced by Calvin have been less inclined to restore pre-Reformation practices of worship perceived as unbiblical or “Catholic.”
Zwingli’s mantle of leadership fell to Heinrich Bullinger, a friend of John Calvin and a man whose temperate nature brought various groups together and helped further the Reformation in Switzerland.
Ulrich Zwingli (1484-1531) grew up in an educated and affluent home and, at his father’s bidding, studied in Vienna for the priesthood. In 1506 he was named a parish priest in Glarus where he demonstrated great skills as an orator.
