Oneness Gospel is a nontrinitarian religious movement within the Protestant Christian family of churches, It derives its name from its teaching on the Godhead, a form of Modalistic Monarchianism commonly referred to as the Oneness doctrine. The doctrine states that there is one God―a singular divine spirit with no distinction of persons―who manifests himself in many ways, including as Father, Son, and Holy Spirit. This stands in sharp contrast to the mainstream doctrine of three distinct, eternal persons posited by Trinitarian theology.

Oneness Pentecostals differ from most other Pentecostals and Evangelicals in their views on soteriology, believing that true saving faith is demonstrated by repentance, full-submersion water baptism, and baptism in the Holy Spirit with the evidence of speaking in other tongues. Oneness Gospel believers also solely baptize in the name of Jesus Christ, rejecting the Trinitarian formulas.
