EXTRA ECCLESIAM NULLA SALUS
Outside the Church there is no salvation. Solemnly defined doctrine that says that no one who culpably refuses to become and remain a member of the Catholic Church can be saved. Positively this means that all who reach their eternal destiny are saved through the Catholic Church, of which Christ is the visible head. This is true even though they nay not have lived as professed Roman Catholics (Fourth Lateran Council, A,D, 1215, Denzinger 802).
