1. Chap. I.

Since you were pleased to acquaint us with the letter sent to you by a Donatist presbyter, although, with the spirit of a true Catholic, you regarded it with contempt, nevertheless, to aid you in seeking his welfare if his folly be not incurable, we beg you to forward to him the following reply. He wrote that an angel had enjoined him to declare to you the episcopal succession ¹ of the Christianity of your town; to you, forsooth, who hold the Christianity not of your own town only, nor of Africa only, but of the whole world, the Christianity which has been published, and is now published to all nations. This proves that they think it a small matter that they themselves are not ashamed of being cut off, and are taking no measures, while they may, to be engrafted anew; they are not content unless they do their utmost to cut others off, and bring them to share their own fate, as withered branches fit for the flames. Wherefore, even if you had yourself been visited by that angel whom he affirms to have appeared to him,--a statement which we regard as a cunning fiction; and if the angel had said to you the very words which he, on the warrant of the alleged command, repeated to you,--even in that case it would have been your duty to remember the words of the apostle: "Though we, or an angel from heaven, preach any other gospel unto you than that we have preached unto you, let him be accursed." ² For to you it was proclaimed by the voice of the Lord Jesus Christ Himself, that His "gospel shall be preached unto all nations, and then shall the end come." ³ To you it has moreover been proclaimed by the writings of the prophets and of the apostles, that the promises were given to Abraham and to his seed, which is Christ, ⁴ when God said unto him: "In thy seed shall all nations of the earth be blessed." Having then such promises, if an angel from heaven were to say to thee, "Let go the Christianity of the whole earth, and cling to the faction of Donatus, the episcopal succession of which is set forth in a letter of their bishop in your town," he ought to be accursed in your estimation; because he would be endeavouring to cut you off from the whole Church, and thrust you into a small party, and make you forfeit your interest in the promises of God.
