The Gospel of Barnabas

Jesus answered: 'As God lives, I have not the devil at my back, but I seek to cast out the devil. Wherefore, for this cause the devil stirs up the world against me, because I am not of this world, but I seek that God may be glorified, who has sent me into the world. Hearken therefore to me, and I will tell you who has the devil at his back. As God lives, in whose presence my soul stands, he who works after the will of the devil, he has the devil at his back, who has put on him the bridle of his will and rules him at his pleasure, making him to run into every iniquity.

Even as a garment changes its name when it changes its owner, although it is all the same cloth: so also men, albeit they are all of one material, are different by reason of the works of him who works in the man. 'If I (as I know) have sinned, wherefore do you not rebuke me as a brother, instead of hating me as an enemy? Truly the members of a body succour one another when they are united with the head, and they that are cut off from the head give it no succour. For the hands of one body do not feel the pain of another body's feet, but that of the body in which they are united. As God lives, in whose presence my soul stands, he who fears and loves God his Creator has the feeling of mercy over them [over] whom God his head has mercy: and seeing that God wills not the death of the sinner, but waits for each one to repent, if you were of that body wherein I am incorporate, as God lives, you would help me to work according to my head.
