Q. 1. If a Pope promotes heresies, teachings that oppose the Catholic Church, can he be removed as a heretic?

A. 1. According to the 1931 Catholic Encyclopaedic Dictionary, "A pope cannot be deposed from his office. An heretical pope necessarily ceases to be head of the Church, for by his heresy he is no longer a member thereof; in the event of his still claiming the Roman see a general council, improperly so called because with the pope, could remove him. But this is not deposition, since by his own act he is no longer pope. In other forms of wrong-doing he remains a member of the visible Church and does not differ from any other sinful ruler whose lawful commands must be obeyed."

In simple English, if the pope promotes a heresy, he ceases to be a member of the Catholic Church.

A pope cannot be deposed from his office because he is no longer pope due to his heresy.

If he will not depart from his office, a general council is called to remove him.

A new pope is elected.

If he commits other form of wrong-doing, he remains as a sinful ruler (Pope) and his lawful commands must be obeyed.
