We turn now to what has been called the Second Generation of Reformers. The First Generation includes Luther, Melanchthon, Zwingli, Bucer, Oecolampadius, et al, who blazed the trail out of the Roman Catholic Church. The Second Generation follows the path and takes it further away from Rome. During this period, beginning in the 1530s, we see the institutional structures of the Protestant churches take shape including church government and confessions and catechisms. Unfortunately for the Protestants, we also see the churches divide further as their respective theologies becomes more developed. The chief architect of this development was the Reformed theologian, John Calvin.
