We having the same spirit of faith, according as it is written, I believed, and therefore have I spoken; we also believe, and therefore speak;

Moreover, our Mediator, when revealed to us, wished the sacrament of our regeneration to be manifest. But for the just men of old it was something hidden, although they also were to be saved by the same faith which was to be revealed in its own time. For we do not dare to prefer the faithful of our own time to the friends of God by whom those prophecies were to be made, since God so announced himself as the God of Abraham, the God of Isaac, the God of Jacob, as to give himself that name forever. If the belief is correct that circumcision served instead of baptism in the saints of old, what shall be said of those who pleased God before this was commanded, except that they pleased him by faith, because, as it is written in Hebrews: “Without faith it is impossible to please God”? “But having the same spirit of faith,” says the apostle, “as it is written: I believed, for which cause I have spoken, we also believe, for which reason we also speak.” He would not have said “the same” unless this very spirit of faith was also theirs. For, just as they, when this same mystery was hidden, believed in the incarnation of Christ which was to come, so we also believe that it has come. Letter , To Dardanus
