Whether it is necessary for the salvation of all, that they should believe explicitly in the mystery of Christ?

❌ Objection 1 : It would seem that it is not necessary for the salvation of all that they should believe explicitly in the mystery of Christ. For man is not bound to believe explicitly what the angels are ignorant about: since the unfolding of faith is the result of Divine revelation, which reaches man by means of the angels, as stated above (Article [6]; FP, Question [111], Article [1]). Now even the angels were in ignorance of the mystery of the Incarnation: hence, according to the commentary of Dionysius (Coel. Hier. vii), it is they who ask (Ps. 23:8): "Who is this king of glory?" and (Is. 63:1): "Who is this that cometh from Edom?" Therefore men were not bound to believe explicitly in the mystery of Christ's Incarnation.

❌ Objection 2 : Further, it is evident that John the Baptist was one of the teachers, and most nigh to Christ, Who said of him (Mt. 11:11) that "there hath not risen among them that are born of women, a greater than" he. Now John the Baptist does not appear to have known the mystery of Christ explicitly, since he asked Christ (Mt. 11:3): "Art Thou He that art to come, or look we for another?" Therefore even the teachers were not bound to explicit faith in Christ.

❌ Objection 3 : Further, many gentiles obtained salvation through the ministry of the angels, as Dionysius states (Coel. Hier. ix). Now it would seem that the gentiles had neither explicit nor implicit faith in Christ, since they received no revelation. Therefore it seems that it was not necessary for the salvation of all to believe explicitly in the mystery of Christ.
