"Considerations on the dubia of the four cardinals"
by John R. T. Lamont, PhD

.....the Pope by pertinaciously maintaining heresy effectively removes himself from office. However, all these explanations agree that a Pope who is juridically guilty of heresy can and must be removed from office. There is no dispute among Catholic theologians on this point – even among theologians like Bellarmine who do not think that a Pope is in fact capable of being a heretic.
            It is to be hoped that the correction of Pope Francis does not have to proceed this far, and that he will either reject the heresies he has announced or resign his office. Removing him from office against his will would require the election of a new Pope, and would probably leave the Church with Francis as an anti-Pope contesting the authority of the new Pope. If Francis refuses to renounce either his heresy or his office, however, this situation will just have to be faced.
