When a leading theologian and churchman confided that there’s no scriptural support for the belief of the “Trinity”, I didn’t know whether he was joking or for real. He was serious. The Trinity (God as three distinct persons: Father, Son and Holy Spirit) often appears as the primary doctrine of mainstream Christianity. And, yet when you study the writings of the apostles, you can clearly see quite a different case. John wrote, for example, “Yes, and our fellowship is with the Father, and with his Son, Jesus Christ.” (1 John 1:3)
So where did the triune concept come from? Is it a valid belief, or does it go beyond what scripture tells us? It is worth a careful study of the scriptures. The Holy Spirit given to us will take what is Jesus’ and make it known.
