The following comes from a November 16 Catholic Herald article by Dan Hitchens:

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.”

Cardinal Burke is one of four cardinals who have written to the Pope asking for a clarification of Amoris Laetitia. They say that the document could be read as contradicting Church teaching on the moral law and on the question of Communion for the remarried. The Pope has declined to reply to the letter.

Asked what would happen if the Pope remained silent, Cardinal Burke replied: “Then we would have to address that situation. There is, in the tradition of the Church, the practice of correction of the Roman Pontiff. It is something that is clearly quite rare. But if there is no response to these questions, then I would say that it would be a question of taking a formal act of correction of a serious error.”

Cardinal Burke said the four cardinals had intervened “because so many people are saying: ‘We’re confused, and we don’t understand why the cardinals or someone in authority doesn’t speak up and help us.’”
