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.
