Thomas Aquinas with his disciples

Thomism, the theological tradition originating with Thomas Aquinas, enjoys widespread acceptance in various forms in the Roman Catholic Church up to the present. After a period of controversy over his teachings, Thomas was declared a Doctor of the Church in 1567. In the nineteenth century, Pope Leo XIII enjoined study of Thomas Aquinas on all Roman Catholic students of theology. The hallmark of Thomism is the complementary relation of reason and faith articulated by Thomas himself. Thomas de Vio Cajetan (1469-1534) and John of St Thomas (1589-1644) are representative theologians.
