Nontrinitarian churches are mixed, ranging from those who believe in the divinity of
Jesus Christ but deny the three persons of the Godhead (known as the
Trinity). These churches adopt the Modalist Monarchianism (heresy stating that the Father, Son, and Holy Spirit are in consecutive modes, that the Holy Spirit is now the mode of Jesus Christ). An example of a Modalist Monarchian would be a Oneness Pentecostal.
Some other nontrinitarian churches range from the Christadelphians, Jehovah's Witnesses, and the polytheist Mormon church.
