Isaiah 44:24 is often quoted as support for the extra-Biblical trinity doctrine. It is claimed that God was all by himself in the creation of the world of mankind, and therefore there could not have been another person there, not unless the other person was also God himself, as is claimed in the trinity dogma. In truth, however, we do not need the extra-Biblical trinity rhetoric about three persons in order for this scripture to be harmonized with other scriptures.
