By Lisa Bourne, LifeSiteNews - The signers of the recent open letter accusing Pope Francis of heresy “went too far,” Bishop Athanasius Schneider said… While the pope in practice has at times denied the truth, he said, the distinction between formal and material heresy must be made. Formal heresy, he said, would happen if the pope were to “publicly and explicitly” in a “formal statement” deny a “revealed truth.”… “There were a lot of ambiguities, I would say more ambiguities,” said Schneider, “and practical collaboration in the spreading of wrong teaching in the Church.”… “they have to be very careful in accusing the pope of formal heresy.”
