His Church also teaches just one set of doctrines, which must be the same as those taught by the apostles (Jude 3). This is the unity of belief to which Scripture calls us (Phil. 1:27, 2:2). Although some Catholics dissent from officially taught doctrines, the Church’s official teachers—the pope and the bishops united with him—have never changed any doctrine.
