Publishes against transubstantiation

At Oxford, Wycliffe published 12 Theses for debate, criticising the Roman Catholic teaching of transubstantiation. The first thesis included: “The consecrated host which we see upon the altar is neither Christ nor any part of Christ, but an efficacious sign of him.” His radical views received widespread condmenation, but none would debate him. He was forced to leave Oxford for his rectorship at Lutterworth.
