Is the Trinity a Christian creation?
The Trinity of God is not of Christianity…its foundation is in the Hebrew Scriptures, Jesus and the New Covenant epistiles simply elaborate on this reality with new revelation; revelation that is undeniable for the one seeking Truth. The Holy Spirit introduces the Trinity first in Genesis 1:1 with the plural noun, Elohim, with a singular verb. The Holy Spirit introduces Himself in Genesis 1:2 actively working in the Creation narrative. The Trinity identified as “Us” and “Our” is seen working in collaboration as they, Father-Son-Spirit, create the complex human genome in Genesis 1:26-28. The Son, Jesus Christ, born of the seed of the (virgin) woman to circumvent the man’s (Adam’s) sin nature (Romans 5:12) is first introduced in Genesis 3:15 who will enter the Realm of Time in flesh and do battle with Satan and “destroy the works of the Devil” (1 John 3:8b) at Golgotha, some 4000-years later.
The battle strategy used by Jesus to defeat Satan is first pictured as the Gospel in Genesis 3:21 with the shedding of innocent blood to produce a “robe of imputed righteousness” (2 Corinthians 5:21; Hebrews 10) to cover the sin of Adam and Eve while Elohim rejects the works of Adam to cover his own sin as seen in the fig leaves used to cover Adam’s sin-nakedness-shame. So then, in the first-three Chapters of the Genesis, The Beginning, the Trinity of God is seen as essential to God Plan in Time and Eternity and to deny this is to call the Holy Spirit a liar…a very dangerous thing to do concerning your eternal destiny.
The Trinity of God is three-distinct personalities working in the Godhead within the Realm of Time to accomplish Divine will setting all things in order, destroying evil and its progenitor and bring peace to the Kingdom of God with obedience to God’s Moral Law as the arbiter of free will.
