Answer: Wealth of the clergy, authority of the pope, and teaching of transubstantiation.
Step-by-step explanation:
Wycliffe criticized the privileged status of the clergy, as well as the wastefulness of their churches and ceremonies. In his work On Divine Dominion, he questioned the papal authority, arguing that the papacy collides with the church’s actual authority, Scripture.
He was also the first to reject the principle of transubstantiation, deeming it impossible, as the indivisibility of temporal units and the eternality of divine wisdom, made the annihilation of created matter unlikely.
