Pentecostal Oneness: Testing the Claims by Scripture. Pentecostal Oneness teaching, sometimes called “Jesus Only,” rejects the historic Christian doctrine of the Trinity. Instead, it insists that God exists only as Jesus, and that true baptism must be “in the name of Jesus” rather than in the triune formula of Matthew 28:19.

The Trinity: The God Who Is Three-in-One. The doctrine of the Trinity stands as one of the central mysteries of the Christian faith. It is not a philosophical abstraction but the reality of God as revealed in Scripture: Father, Son, and Holy Spirit — three distinct persons, yet one God. The term Trinity (trias in Greek, trinitas in Latin) does not appear in the Bible, but the reality saturates both Old and New Testaments.
