Roman Catholic theology refers to the "Roman Catholic teachings" (cf Latin Rite) of the Catholic Church which bases its conclusions on Scripture and Sacred Tradition, as interpreted by Magisterium. The Church teaches that salvation comes through faith in Jesus Christ, keeping of the Ten commandments and receiving the sacraments. There are a number of teachings which differentiate the Latin Rite Catholic Church from other Christian churches and even from the Eastern Rite Catholic Churches. The most notable differences include Catholic beliefs in the existence of Purgatory, the Pope as the "Vicar of Christ on Earth", papal infallibility, and the Immaculate Conception of Mary.
