25 Thus St. Jerome is in complete agreement with St. Augustine, who sums up the general belief of Christian antiquity when he says: Holy Scripture is invested with supreme authority by reason of its sure and momentous teachings regarding the faith. Whatever, then, it tells us of Enoch, Elias and Moses - that we believe. We do not, for instance, believe that God's Son was born of the Virgin Mary simply because He could not otherwise have appeared in the flesh and 'walked amongst men' - as Faustus would have it - but we believe it simply because it is written in Scripture; and unless we believe in Scripture we can neither be Christians nor be saved.
