Is Jesus the only person in the Godhead?

When Moses in Deutonomy 6:4 says, “Hear, 0 Israel, The LORD our God is one LORD,” are we to understand that therefore Jesus Christ is the only Person in the Godhead?

No, it would be a very serious and fundamental error to do so, upsetting and dislocating the whole revealed truth concerning the Godhead, as it has pleased God to reveal Himself in His Word.

This is the teaching of a certain fearful system of error, which we need not name, but which has, alas, adherents to-day; but I question whether there is one point of God’s revealed truth on which they are sound. It is a false system built on lies.

Moses’ words are perfectly true: “The LORD our God is One LORD,” but in that Unity there are three distinct Divine Persons or Subsistences —Father, Son and Spirit—co-equal, co-eternal, co-substantial (see e.g. Matthew 3:16-17; Matthew 28:19; 2 Corinthians 13:14; Revelation 1:4-6, etc., etc.). The last expression means that each glorious Person of the Triune God possesses the entire Divine Substance or Essence. God is Spirit and as such is invisible. “No man hath seen God at any time, the only-begotten Son, who is in the bosom of the Father, He hath declared Him.” “In the beginning was the Word and the Word was with God and the Word was God.” . . . “and the Word became flesh and dwelt among us and we beheld His glory, the glory of the Only-begotten of the Father full of grace and truth” (John 1:1-14). He was “the express image of God’s Person”; “the image of the Invisible God” (John 10:14, 18; Hebrews 1: 3; Colossians 1:15). Only in the Lord Jesus Christ is the Father revealed by the Spirit. Let us not reason about it, but bow and worship. If we do not understand our own tripartite nature, how can we claim to comprehend the Infinite, the “One God in Three Persons”?
