48 This is a brief reply to Faustus in behalf of the character of the patriarchs and prophets. It is the reply of the babes of our faith, among whom I would reckon myself, inasmuch as I would not find fault with the life of the ancient saints, even if I did not understand its mystical character. Their life is proclaimed to us with approval by the apostles in their Gospel, as they themselves in their prophecy foretold the future apostles, that the two Testaments, like the seraphim, might cry to one another, "Holy, holy, holy is the Lord God of hosts." When Faustus, instead of the vague general accusation which he makes here, condemns particular actions in the lives of the patriarchs and the prophets, the Lord their God, and ours also, will assist me to reply suitably and appropriately to the separate charges. For the present, the reader must choose whether to believe the commendation of the Apostle Paul or the accusations of Faustus the Manichæan.
