Epistle to the Philadelphians (Long Version)
Chapter 6: Do Not Convert to Judaism
If anyone preaches the one God of the law and the prophets, but denies Christ to be the Son of God, he is a liar, just like his father the devil, and is falsely called a Jew, only possessing mere physical circumcision. If anyone confesses Christ Jesus the Lord, but denies the God of the law and the prophets, saying that the Father of Christ is not the Maker of heaven and earth, he has not remained in the truth any more than his father the devil, and is a disciple of Simon Magus, not of the Holy Spirit.
If anyone says there is one God and also confesses Christ Jesus, but thinks the Lord to be just a man, and not the only-begotten God, and Wisdom, and the Word of God, and considers Him to consist merely of a soul and body, such a one is a serpent, preaching deceit and error for the downfall of people. And such a man is poor in understanding, even as by name he is an Ebionite. If anyone confesses the truths mentioned but calls lawful wedlock and the procreation of children destruction and pollution or considers certain kinds of food abominable, such a one has the apostate dragon dwelling within him.
If anyone confesses the Father, and the Son, and the Holy Ghost, and praises the creation, but calls the incarnation merely an appearance and is ashamed of the passion, such a one has denied the faith, not less than the Jews who killed Christ. If anyone confesses these things, and that God the Word did dwell in a human body, being within it as the Word, just as the soul is in the body, because it was God that inhabited it, and not a human soul, but claims that unlawful unions are good, and places the highest happiness in pleasure, as does the man who is falsely called a Nicolaitan, this person can neither be a lover of God nor a lover of Christ, but is a corrupter of his own flesh, and therefore void of the Holy Spirit and a stranger to Christ.
All such persons are only monuments and tombs of the dead, upon which are written only the names of dead men. Flee, therefore, the wicked devices and snares of the spirit which now works in the children of this world, lest at any time, being overcome, you grow weak in your love.
But be all joined together with an undivided heart and a willing mind, "being of one accord and of one judgment," always having the same opinion about the same things, both when you are at ease and in danger, both in sorrow and in joy.
I thank God, through Jesus Christ, that I have a good conscience in respect to you and that no one has the power to boast, either privately or publicly, that I have burdened anyone either in much or in little. And I wish for all among whom I have spoken, that they may not possess that for a testimony against them.
