To be incorruptible is to participate in divinity

For he who has not the knowledge of good is wicked: for there is one good, the Father; and to be ignorant of the Father is death, as to know Him is eternal life, through participation in the power of the incorrupt One. And to be incorruptible is to participate in divinity; but revolt from the knowledge of God brings corruption.

Clement quotes a lost logoi of Jesus

For it is not in the way of envy that the Lord announced in a Gospel, “My mystery is to me, and to the sons of my house;” placing the election in safety, and beyond anxiety; so that the things pertaining to what it has chosen and taken may be above the reach of envy.

Clement quotes Clement of Rome as an Apostle

Moreover, in the Epistle to the Corinthians, the Apostle Clement also, drawing a picture of the Gnostic, says: “For who that has sojourned among you has not proved your perfect and firm faith? and has not admired your sound and gentle piety? and has not celebrated the munificent style of your hospitality? and has not felicitated your complete and sure knowledge? For ye did all things impartially, and walked in the ordinances of God;” and so forth.
