Before men or angels were created, the Word was with God, and was God. TA 23.1
The world was made by Him, “and without Him was not anything made that was made.” If Christ made all things, He existed before all things. The words spoken in regard to this are so decisive that no one need be left in doubt. Christ was God essentially, and in the highest sense. He was with God from all eternity, God over all, blessed forevermore. TA 23.2
The Lord Jesus Christ, the divine Son of God, existed from eternity, a distinct person, yet one with the Father. He was the surpassing glory of heaven. He was the commander of the heavenly intelligences, and the adoring homage of the angels was received by Him as His right.—The Review and Herald, April 5, 1906. TA 23.3
Through Solomon Christ declared: “The Lord possessed Me in the beginning of His way, before His works of old. I was set up from everlasting, from the beginning, or ever the earth was.... When He gave to the sea His decree, that the waters should not pass His commandment; when He appointed the foundations of the earth; then I was by Him, as one brought up with Him; and I was daily His delight, rejoicing always before Him.” [Proverbs 8:22-25, 29, 30.] TA 23.4
In speaking of His pre-existence, Christ carries the mind back through dateless ages. He assures us that there never was a time when He was not in close fellowship with the eternal God. He ... had been with God as one brought up with Him.—The Signs of the Times, August 29, 1900. TA 24.1
What is the work of angels in comparison with His [Christ's] condescension? His throne is from everlasting. He has reared every arch and pillar in nature's great temple.—In Heavenly Places, 40. TA 24.2
Christ the Word, the Only Begotten of God, was one with the eternal Father—one in nature, in character, and in purpose—the only being in all the universe that could enter into all the counsels and purposes of God.—The Great Controversy, 493. TA 24.3
