What about other Catholic dogma? Purgatory, 7 Sacraments, Immaculate Conception of Mary, Assumption of Mary, the Real Presence, Papal infallibility, the Catholic Church being the true and only Church of Christ, priests can absolve sins, mortal sin, necessity of baptism for salvation, sanctity of marriage, abortion being immoral, contraception being immoral, and all other Catholic dogma? Only the dogma of the Trinity and Divinity of Christ have to be accepted as the Catholic Faith that is necessary for salvation. If this is the case, then all "Christians" have the true Faith.
