given promise to Abraham, that He would make his seed as the stars of heaven,[1] and Him who, by His Son Christ Jesus, has called us to the knowledge of Himself, from the worship of stones, so that those who were not a people were made a people, and she beloved who was not beloved[2]—declares that John, when preparing the way for Christ, said to those who were boasting of their relationship [to Abraham] according to the flesh, but who had their mind tinged and stuffed with all manner of evil, preaching that repentance which should call them back from their evil doings, said, "O generation of vipers, who hath shown you to flee from the wrath to come?
