Cardinal Raymond Burke has said it may be necessary to make a "formal act of correction" if Pope Francis doesn't answer a letter from four cardinals asking him to clarify aspects of Amoris Laetitia.

In an interview with Edward Pentin of National Catholic Register, Cardinal Burke said that if the Pope were to teach error or heresy, “It is the duty in such cases, and historically it has happened, of cardinals and bishops to make clear that the Pope is teaching error and to ask him to correct it.”
