JESUS called God the only true God. (John 17:3) Never did he refer to God as a deity of plural persons. That is why nowhere in the Bible is anyone but Jehovah called Almighty. Otherwise, it voids the meaning of the word almighty. Neither Jesus nor the holy spirit is ever called that, for Jehovah alone is supreme. At Genesis 17:1 he declares: I am God Almighty. And Exodus 18:11 says: Jehovah is greater than all the other gods.
ONE of the main reasons why Jesus came to earth also has a direct bearing on the Trinity. The Bible states: There is one God, and one mediator between God and men, a man, Christ Jesus, who gave himself a corresponding ransom for all.1 Timothy 2:5, 6.
Jesus, no more and no less than a perfect human, became a ransom that compensated exactly for what Adam lostthe right to perfect human life on earth. So Jesus could rightly be called the last Adam by the apostle Paul, who said in the same context: Just as in Adam all are dying, so also in the Christ all will be made alive. (1 Corinthians 15:22, 45) The perfect human life of Jesus was the corresponding ransom required by divine justiceno more, no less. A basic principle even of human justice is that the price paid should fit the wrong committed.
If Jesus, were part of a Godhead, the ransom price would have been infinitely higher than what Gods own Law required. (Exodus 21:23-25; Leviticus 24:19-21) It was only a perfect human, Adam, who sinned in Eden, not God. So the ransom, to be truly in line with Gods justice, had to be strictly an equivalenta perfect human, the last Adam. Thus, when God sent Jesus to earth as the ransom, he made Jesus to be what would satisfy justice, not an incarnation, not a god-man, but a perfect man, lower than angels. (Hebrews 2:9; compare Psalm 8:5, 6.) How could any part of an almighty GodheadFather, Son, or holy spiritever be lower than angels?
