3 For this purpose, then, he had come that he might win her first, and free her from slavery, while he conferred salvation upon men, by making himself known to them. For since the angels ruled the world ill because each one of them coveted the principal power for himself, he had come to amend matters, and had descended, transfigured and assimilated to powers and principalities and angels, so that he might appear among men to be a man, while yet he was not a man; and that thus he was thought to have suffered in Judæa, when he had not suffered.
Moreover, the prophets uttered their predictions under the inspiration of those angels who formed the world; for which reason those who place their trust in him and Helena no longer regarded them, but, as being free, live as they please; for men are saved through his grace, and not on account of their own righteous actions. For such deeds are not righteous in the nature of things, but by mere accident, just as those angels who made the world, have thought fit to constitute them, seeking, by means of such precepts, to bring men into bondage. On this account, he pledged himself that the world should be dissolved, and that those who are his should be freed from the rule of them who made the world.
