Martin Luther's condemnation of "justification by works" clearly condemned Ockhamism. Some proponents of ecumenism argue that the Thomist view of salvation is not opposed to Luther's view of grace, and, since Ockhamism was rejected as Semipelagian by the Catholic Church at the Council of Trent, theology of salvation need not pose a bar to Protestant-Catholic reunion. (The major streams of modern Catholic thought on the theology of salvation are Thomism and Molinism, a theology developed by Jesuit theologian Luis Molina in the 16th century and also held today by some Protestants such as William Lane Craig and Alvin Plantinga.)
