You arrogant people! The man disagrees with your heresy so you attack his age! As though God could not choose the young and humble to know and believe His Truth!
CM/DM, Was Innocent II a heretic?
Was the last true Pope Honorius II in 1130 AD?
First of all it was Innocent III, and no as a matter of fact he was not a heretic, since the necessity for water baptism was not dogmatically defined until the Council of Vienne about a hundred years later, and this was not a dogma held by unanimous consent of the Church Fathers.
If he had written this letter after Vienne, guess what- you still could not call him an antipope, because it is a private letter and would not constitute public or manifest heresy. Most people would be invincibly ignorant of the matter.
If he made it a public teaching after Vienne, heretic and to be rejected.
Furthermore do you believe everything you read? A priest who had persevered in the Holy Catholic Faith but was never baptized? :detective:
Just because a certain proposition has not been condemned by name doesn't mean that it's not heresy.
The dogmatic canons on baptism admit of NO exceptions, and if we want to argue that someone receives baptism after death by some heavenly minister, well sorry but that contradicts Florence, which states that those who die with original sin go straight to hell, not that they get help from some spirit after their death. Augustine and Ambrose lived before this decree also, so no no no they were not heretics.
