Pope
Eugene IV, Council of Florence, The Athanasian Creed, Sess. 8, Nov. 22, 1439, ex
cathedra: “Whoever wishes to be saved, needs above all to hold the Catholic
faith; unless each one preserves this whole and inviolate, he will without a
doubt perish in eternity.” (Decrees of the Ecumenical Councils, Vol. 1, pp.
550-553; Denzinger 39-40.)
"Believe in the Lord Jesus, and you will be
saved." Acts 16:31.
