3 I have also largely demonstrated, that the Word, namely the Son, was always with the Father; and that Wisdom also, which is the Spirit, was present with Him, anterior to all creation, He declares by Solomon: “God by Wisdom founded the earth, and by understanding has He established the heaven. By His knowledge the depths burst forth, and the clouds dropped down the dew.” And again: “The Lord created me the beginning of His ways in His work: He set me up from everlasting, in the beginning, before He made the earth, before He established the depths, and before the fountains of waters gushed forth; before the mountains were made strong, and before all the hills, He brought me forth.” And again: “When He prepared the heaven, I was with Him, and when He established the fountains of the deep; when He made the foundations of the earth strong, I was with Him preparing [them]. I was He in whom He rejoiced, and throughout all time I was daily glad before His face, when He rejoiced at the completion of the world, and was delighted in the sons of men.”
