Augustine of Hippo

Those just men also were saved by their salutary faith in him as man and God. They, before he came in the flesh, believed that he was to come in the flesh. Our faith is the same as theirs, since they believed that this would be, while we believe that it has come to pass. Hence, the apostle Paul says: "But having the same spirit of faith, as it is written: I believed for which reason I have spoken: we also believe for which reason we also speak." If, then, those who foretold that Christ would come in the flesh had the same faith as those who have recorded his coming, these religious mysteries could vary according to the diversity of times yet all refer most harmoniously to the unity of the same faith.
