A French Calvinist theologian who was a colleague and successor to Calvin both in Geneva and within the Reformed movement as a whole. Originally a humanist in the Roman Catholic Church, Beza began reading Reformed literature and eventually fled to Geneva in 1548. Finding no work there, he taught Greek in Lausanne until 1558, when Calvin offered Beza a position at the newly founded Geneva Academy. After Calvin’s death in 1564, Beza became the effective leader of the Reformed church in Geneva, handling disputes with Lutheranism, particularly regarding the Lord’s Supper. Although in general Beza aligned theologically with Calvin, he did modify and develop some particular doctrines, such as supralapsarian predestination, and his concern for doctrinal details laid the groundwork for the growth of Reformed scholasticism.
