Acts 8:37

If thou believest, &c. The Scripture many times mentions one disposition, when others no less necessary are supposed, as here a sorrow for sins, a firm hope, love of God, &c. (Witham) --- Faith is thus seen to be a necessary predisposition in the adult, for the reception of baptism. They must answer for themselves; but infants are baptized in the faith of the Church. Their sponsors, who receive them from the font, answer for them. (Denis the Carthusian) --- And as the defilement was not personal, but that of others, so are they purified by the faith of others.
