Full Answer
The doctrine of the Trinity does not mean Christians believe in three gods, but rather in one God who exists as three divine Persons [1]. The Bible plainly reveals deity in terms of three divine Persons who form a single God [2].
Scripture establishes the oneness of God: 'Hear, O Israel: The Lord our God, the Lord is one' (Deuteronomy 6:4). Yet it also reveals three distinct divine Persons:
**The Father** is identified as God (1 Timothy 2:5; Malachi 2:10).
**The Son (Jesus Christ)** is revealed as divine: 'In the beginning was the Word, and the Word was with God, and the Word was God' (John 1:1). Thomas declared to the risen Jesus, 'My Lord and my God!' (John 20:28). Paul wrote that in Christ 'all the fullness of the Deity lives in bodily form' (Colossians 2:9).
**The Holy Spirit** is presented as a divine Person: Peter said, 'Ananias, how is it that Satan has so filled your heart that you have lied to the Holy Spirit?' (Acts 5:3), and later, 'You have not lied just to human beings, but to God' (Acts 5:4), equating the Holy Spirit with God. The Spirit is described as having will (1 Corinthians 12:11) and can be grieved (Ephesians 4:30).
All three Persons are involved in salvation and worship together (Ephesians 2:18; Matthew 28:19), demonstrating their co-equal divine nature within the unity of one God.
