“But all Scripture is divided into two Testaments. That which preceded the advent and passion of Christ—that is, the law and the prophets—is called the Old; but those things which were written after His resurrection are named the New Testament. The Jews make use of the Old, we of the New.”
Verum Scriptura omnis in duo Testamenta diuisa est. Illud quod aduentum passionemque Christi antecessit, id est lex et prophetae, Vetus dicitur; ea uero quae post resurrectionem eius scripta sunt, Nouum Testamentum nominantur. Iudaei Veteri utuntur, nos nouo.
