that partaketh of milk is unskilful in the word of righteousness; for he is a babe, being instructed with the first lessons. But solid food belongs to those who are of full age, who by reason of use have their senses exercised so as to distinguish between good and evil. Wherefore, leaving the first principles of the doctrine of Christ, let us go on to perfection.”[795] Barnabas, too, who in person preached the word along with the apostle in the ministry of the Gentiles, says, “I write to you most simply, that ye may understand.” Then below, exhibiting already a clearer trace of gnostic tradition, he says, “What says the other prophet Moses to them? Lo, thus saith the Lord God, Enter ye into the good land which the Lord God sware, the God of Abraham, and Isaac, and Jacob; and ye received for an inheritance that land, flowing with milk and honey. What says knowledge? Learn, hope, it says, in Jesus, who is to be manifested to you in the flesh. For man is the suffering land; for from the face of the ground was the formation of Adam. What, then, does it say in reference to the good land, flowing with milk and honey? Blessed be our Lord, brethren, who has put into our hearts wisdom, and the understanding of His secrets. For the prophet says, “Who shall understand the Lord’s parable but the wise and understanding, and he that loves his Lord?” It is but for few to comprehend these things. 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;”[796] 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. 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. Again the prophet says: “And I will give thee treasures, concealed, dark, unseen; that they may know that I am the Lord.”[797] Similarly David sings: “For, lo, Thou hast loved truth; the obscure and hidden things of wisdom hast Thou showed me.”[798] “Day utters speech to day”[799] (what is clearly written), “and night to night proclaims knowledge” (which is hidden in a mystic veil); “and there are no words or utterances whose voices shall not be heard” by God, who said, “Shall one do what is secret, and I shall not see him?”
