Many often confuse the trinity doctrine with the oneness doctrine, which I prefer to call modalism. I have even found some trinitarians who use the arguments of modalism to promote the trinity, when actually such arguments often are not in agreement with orthodox trinitarian dogma.
That which is usually called “oneness doctrine” actually teaches that Jesus is his God and that Jesus is his Father; that is, that there is one God expressed in three modes: Father, Son and Holy Spirit. This teaching claims that these three are not three persons, but that they are all one person (unlike the trinity, which claims that these three are all three distinct persons of the one God). The oneness doctrine is also referred to as modalism, although most oneness believers deny that they are “modalists”. The basic ideas related this doctrine called “oneness“, often confused with “trinitarianism”, appears to have developed earlier than the trinity doctrine.
In reality, however, both the trinity doctrine, and the “oneness doctrine” — as that term is usually used to promote the doctrine that is named as “oneness” — are but doctrines of men. The true “oneness” doctrine taught by Jesus involved Jesus’ oneness with his God and also with his followers. — John 10:30,38; 14:20; 17:10,21,22.
