Father Michel de Bay

Also known as

  • Michel Baius


Theologian, author of a system known as Baianism. Ordained in 1541, he taught philosophy at Louvain, where he became president of the College Adrien and professor of Scripture. His system, which ignored the supernatural, was a mixture of Pelagianism and Calvinism. About 1559, propositions from his lectures were condemned by the Sorbonne, and later by Pope Pius V. Baius finally submitted to Pope Gregory XIII in 1579, but his teachings had prepared the way for Jansenism.
