Thomas Cajetan
In the late medieval period, statements of this papal power were common in the works of theologians as well. For example, Domingo Bañez attributed to the Pope the “definitive power to declare the truths of the faith," and Thomas Cajetan, in expanding the distinction made by St. Thomas Aquinas, drew a line between personal faith manifested in theologians and the authoritative faith presented as a matter of judgment by the pope.
