The Roman Catholic Church has four key beliefs that distinguish it from Protestant denominations: 1) the role of tradition in addition to scripture in guiding doctrine, 2) belief in 7 sacraments including baptism, communion, confirmation and anointing of the sick, 3) the existence of purgatory as a state of purification for sins before entering heaven, and 4) the communion of saints which recognizes spiritual connection between living members, souls in purgatory, and saints in heaven. The document then provides details on each of these distinguishing beliefs.
