"The Oneness Pentecostals stress that God is absolutely one (Isa 44:6, 8, 24)—that is, one without distinction of persons. There are no distinctions in God’s eternal being, and the Godhead does not consist of three centers of consciousness (as some Trinitarians hold). Moreover, in Jesus dwells all the fullness of the Godhead bodily (Col 2:9)." (Oneness Pentecostal Confession. 9,34. 2007)
The obligation to show respect for others does not come from a soft sentimentalism but is rooted in the theological truth that we are all created in the image of God. How we speak to each other should reflect the honor and respect we owe each other as fellow human beings.
