Jesus' Name doctrine is a minority nontrinitarian theology, characterised by a belief that baptism must be performed "in the name of Jesus", rather than the more common Trinitarian formula "in the name of the Father, and of the Son, and of the Holy Spirit". The Jesus' Name doctrine includes the "Oneness" of God. This doctrine rejects the mainstream Trinitarian belief of Three Persons in One God, and holds that Father, Son and Holy Spirit are three modes of a singular God. Those in Oneness churches believe that "Jesus" is the correct and entire name of God.
