Calvinism
The rising importance of the Reformed churches and Calvin appened in the second phase of the Protestant Reformation, when evangelical churches began to form, after Martin Luther, another important Reformer, had been excommunicated from the Roman Catholic Church. Calvin was a French exile in Geneva City. He had signed the Lutheran Augsburg Confession in 1540, but his importance came from the Swiss Reformation. It was not Lutheran but followed Huldrych Zwingli and then Calvin.
