“I, wisdom, dwell in counsel, and am present in learned thoughts… The Lord possessed me in the beginning of his ways, before he made any thing from the beginning. I was set up from eternity, and of old, before the earth was made… I was with him forming all things… Blessed are they that keep my ways… He that shall find me, shall find life, and shall have salvation from the Lord. But he that shall sin against me shall hurt his own soul…. Come, eat my bread, and drink the wine which I have mingled for you… The fear of the Lord is the beginning of wisdom: and the knowledge of the holy is prudence.” (Proverbs viii, 12, 22-23, 30, 32. 35-36, ix, 5, 10)

“In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God. All things were made by him: and without him was made nothing that was made. In him was life, and the life was the light of men… [A]s many as received him, he gave to them power to be made the sons of God, to them that believe in his name…. And the Word was made flesh, and dwelt among us: and we saw his glory, the glory as of the only begotten of the Father, full of grace and truth… For the law was given by Moses, grace and truth by Jesus Christ. No man hath seen God at any time: the only begotten Son who is in the bosom of the Father, he hath declared him.” (St. John i, 1-4, 12, 14, 17-18)
