There is only one God, but He consists of three distinct persons—Father, Son and Holy Spirit.
The word “trinity” is not found in Scripture. It is a word used by Christians to express the doctrine of the unity of God as consisting of three distinct Persons. This word is derived from the Greek word trias, first used by Theophilus (A.D. 168-183), or from the Latin trinitas, first used by Tertullian (A.D. 220), to express this doctrine.
This is the wondrous reality of God:
God is one, and there is but one God (Deuteronomy 6:4; 1 Kings 8:60; Isaiah 44:6; Mark 12:29, 32; John 10:30).
The Father is a distinct divine Person (hypostasis, subsistentia, persona, suppositum intellectuale), distinct from the Son and the Holy Spirit.
Jesus Christ is truly God, and yet is a Person distinct from the Father and the Holy Spirit (John 20:30-31).
The Holy Spirit is also a distinct divine Person.
Notice the use of the words “us” and “our” when the Son of God (“The Word”) created Man (Genesis 1:26).
Although equal in divinity, the Father is in a position of authority or hierarchy over Jesus Christ, incarnate Son of God (John 14:28, 13:16; 1 Corinthians 11:3; Philippians 2:6-8).
