The Word of God is Christ's title, as the personal Revealer in Himself of the Godhead, even before His incarnation, involving personality (not merely the Intelligence of God) and Divinity. In the introduction of John's Gospel and that of his Epistle, and in his Revelation 19:13, at once with God and Himself God, by whom God made all things. Philo's Logos ("word") on the contrary excludes personality, and is identical at times with God, at other times with the world. By word man, who is in God's image, makes known his mind; so the Word is the outcome of God's essence (Hebrews 4:12-13; 1 Peter 1:25; Genesis 1:3); by the Word He made the universe (Psalm 33:6). The Medium of every external act of God (Hebrews 1:1-3) in the physical and spiritual creations.
