Trinity
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.
The propositions involved in the doctrine are these:
That God is one, and that there is but one God (Deut. 6:4; 1 Kings 8:60; Isa. 44:6; Mark 12:29, 32; John 10:30).
That the Father is a distinct divine Person (hypostasis, subsistentia, persona, suppositum intellectuale), distinct from the Son and the Holy Spirit.
That Jesus Christ was truly God, and yet was a Person distinct from the Father and the Holy Spirit. (John 20:30-31)
That 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 (Gen. 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 Cor. 11:3; Phil. 2:6-8).
