👉 Vaticanism is a political ideology that emphasizes the importance of the Papacy (the Pope) as the ultimate authority and source of moral guidance in the Catholic Church. This ideology was developed by Pope Pius XI, who introduced it into the Catholic Church in 1938. The term "vatican" refers to the role of the Pope as the "Pilgrim of the Papacy", which implies that he is a spiritual leader and guide for the faithful.
