Apostolic Fathers

Epistle of Polycarp to the Philippians 7:1

For whosoever does not confess that Jesus Christ has come in the flesh, is antichrist;” and whosoever does not confess the testimony of the cross, is of the devil; and whosoever perverts the oracles of the Lord to his own lusts, and says that there is neither a resurrection nor a judgment, he is the first-born of Satan. Wherefore, forsaking the vanity of many, and their false doctrines, let us return to the word which has been handed down to us from the beginning; “watching unto prayer,” and persevering in fasting; beseeching in our supplications the all-seeing Godnot to lead us into temptation,” as the Lord has said: “The spirit truly is willing, but the flesh is weak.”

NT Apocrypha/Pseudepigrapha

Gospel of Nicodemus, Part II: The Descent into Hell 9:1

But the Lord holding the hand of Adam delivered him unto Michael the archangel, and all the saints followed Michael the archangel, and he brought them all into the glory and beauty (grace) of paradise. And there met with them two men, ancients of days, and when they were asked of the saints: Who are ye that have not yet been dead in hell with us and are set in paradise in the body? then one of them answering, said: I am Enoch which was translated hither by the word of the Lord, and this that is with me is Elias the Thesbite which was taken up in a chariot of fire: and up to this day we have not tasted death, but we are received unto the coming of Antichrist to fight against him with signs and wonders of God, and to be slain of him in Jerusalem, and after three days and a half to be taken up again alive on the clouds.
