Throughout the OT and NT God has always been exalted as “one.” The “trinity” theory is contrary to the Bible. Many scriptures such as 1 Timothy 3:16 declare one God. Did not the trinity theory come about in the 2nd and 3rd centuries? The apostles didn’t teach it, did they?

The basic thing to realize is that the apostles experienced God as Father, Son, and Holy Spirit in their lives and ministry. They came to recognize God as Father in their daily contact with Jesus, God as Son in the presence of Jesus, and God as Holy Spirit through the experience of Pentecost. The Trinity is more than doctrine. It was and is to enter into a life-changing experience. None of this diminishes the fact that God is one.
