How can anyone hope to convince a typical BODer like Ambrose about anything, when Ambrose believes that this CLEAR DOGMA below does not mean that for salvation one has to explicitly believe in the Incarnation (Christ) and the Trinity. Is there any dogma that is clearer? It is the infallible unanimous opinion of the Fathers (clearly expressed in the Athanasian Creed), and not a Father, Doctor or Saint has taught otherwise.
Yet Ambrose and ALL the BODers deny it, for they believe that someone can be saved who has no explicit belief in the Trinity and the Incarnation (nor explicit desire to be baptized, nor martyred, nor to be a Catholic.
Pope Eugene IV, Council of Florence, 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.– But the Catholic faith is this, that we worship one God in the Trinity, and the Trinity in unity... Therefore let him who wishes to be saved, think thus concerning the Trinity. “But it is necessary for eternal salvation that he faithfully believe also in the incarnation of our Lord Jesus Christ...the Son of God is God and man...– This is the Catholic faith; unless each one believes this faithfully and firmly, he cannot be saved.”
