Trinity, What is it?

Our God is a Trinity. This means there are three persons in one God and not three Gods.

The persons are known as the Father, the Son, and the Holy Spirit, and they have all always existed as three distinct persons. The person of the Father is not the same person as the Son. The person of the Son is not the same person as the Holy Spirit. The person of the Holy Spirit is not the same person as the Father. If you take away any one, there is no God. God has always been a trinity from all eternity: “From everlasting to everlasting, You are God,” (Psalm 90:2).

God is not one person who took three forms, i.e., the Father who became the Son, who then became the Holy Spirit. This belief is known today as the “Jesus Only Movement” (also known as Oneness Pentecostalism). It is taught by the United Apostolic and United Pentecostal churches and is an incorrect teaching.
Nor is God only one person as the Jehovah’s Witnesses, the Way International, and the Christadelphians teach. (These groups are classified as non-Christian cults).

The Bible says that there is only one God. Yet, it says that Jesus is God (John 1:1, 14). It says that the Father is God (Phil. 1:2), and it says that the Holy Spirit is God (Acts 5:3-4). Since the Son speaks to the Father, they are distinct persons. Since the Holy Spirit speaks also (Acts 13:2), He is a distinct person. There is one God who exists in three persons.
