One of the issues Protestants and Catholics disagree on is the idea that Mary the mother of Jesus didn’t have any other children and she in fact was born a virgin and without sin. This is called the Immaculate Conception and it was issued in a Papal Bull on December 8, 1854 by Pope Pious IX. In Latin it’s called Ineffabilis Deus and is an integral part of the Roman Catholic Church’s beliefs. This is a picture of Pious IX and some of his cardinals.
