God wants us to use our minds and PROVE what is right.
"Now these were more noble than those in Thessalonica, for they received the Word with all readiness of mind and examined the Scriptures daily to see if these things were so." (Acts 17:11, Holy Bible in its Original Order - A Faithful Version - HBFV)
It is the duty of ever believer is Jesus Christ to PROVE whether the Trinity doctrine is the truth or not.
Origin of the Teaching
The doctrine of a Triune God is a dogma from the Catholic Church that was adopted by Protestant churches. The Catholic Encyclopedia even boldly notes that the idea of a triune Godhead did NOT come from in-depth Bible study or research.
"In Scripture there is as yet no single term by which the Three Divine Persons are denoted together. The word trias (of which the Latin trinitas is a translation) is first found in Theophilus of Antioch about A.D. 180." (Catholic Encyclopedia, Volume XV, 1912)
Is there Biblical proof?
The most well-know Bible verses used to 'prove' the Trinity is found in 1John 5, especially in the King James Version Bible.
"This is he that came by water and blood, [even] Jesus Christ; not by water only, but by water and blood. And it is the Spirit that beareth witness, because the Spirit is truth. For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one. And there are three that bear witness in earth, the Spirit, and the water, and the blood: and these three agree in one." (1John 5:6-8, KJV)
Theologians, however, recognize that words were inserted into this section of scripture probably as late as the 8th century. The JFB commentary states that the only Greek manuscripts which support the words "in heaven, the father, etc." is one from Dublin, and that it is apparent the words in question were added later to the margin.
The most accurate modern translation of these verses in the following.
"This is He Who came by water and blood - Jesus the Christ; not by water only, but by water and blood. And it is the Spirit that bears witness because the Spirit is the truth. For there are three that bear witness on the earth: the Spirit, and the water, and the blood; and these three witness unto the one truth." (HBFV)
Who was and is Jesus?
Who was, and is, Jesus Christ? Jesus, the Eternal, self-existent One is the Spokesman for God Almighty and the Creator of all things as outlined in the Book of Genesis. He is also the LORD God of the Old Testament who became Christ in the flesh in the Gospels. He is the one who will return back to this earth to re-establish the Kingdom of God (the true gospel message), rule from His throne in Jerusalem for more than 1,000 years and rebuild this world from the ground up according to God's original standards. Once that is accomplished and the world is cleansed with fire, He will turn it over to God the Father, who along with the Holy City in the third heaven, will come to this earth which will then become the new headquarters of the universe (Revelation 21-22).
The apostle Paul makes it abundantly clear that Jesus was not only the Deity of the Old Testament but was also the Being that led the Israelites out of bondage (1Corinthians 10:1-4).
Revealing the Father
God's word makes a distinction between Jesus Christ and God the Father. Jesus came to reveal God the Father to the world as no one had seen him previously (John 1:18). He came to also reveal that within the Godhead a family relationship existed. If Jesus Christ had not come to reveal his Father there would have been no other means by which we could have known him.
"All things were delivered to Me by My Father; and no one knows the Son except the Father; neither does anyone know the Father except the Son, and the one to whom the Son personally chooses to reveal Him." (Matthew 11:27, HBFV)
The Holy Spirit
Jesus Christ is, was and always will be God. You can search the Bible from cover to cover, however, and you will not find ANYWHERE that states the Spirit is God just like God the Father and Jesus are God. The Bible simply does not teach that the Holy Spirit is a third member of the divine family.
The personality of Jesus is thoroughly provable from the Bible, but there is no such proof for a personality of the Holy Spirit. In the Old Testament, God's Spirit is pictured as His power - the power by which the One who became Jesus Christ created the entirety of the universe.
The Holy Spirit is the very power of God through which Jesus came to the earth through Mary's womb (Matthew 1:18). This fact was confirmed by an angel who visited Joseph (verse 20).
It is this same spirit, according to Paul the apostle, that God puts in the mind of those who are converted - making them one of his children and giving them an opportunity to inherit all things through Christ (Romans 8:16, Hebrews 1:2, Galatians 4:7).
God is actually a family, not a closed Trinity. The original language word used many times for "God" in the Old Testament is Elohim - a uniplural noun like our words "group" or "church" or "family." This word shows that God, or the Godhead, is composed of at least two Beings with the possibility of more.
The Trinity doctrine hides God's PURPOSE and PLAN for man. Such a teaching leads people astray from God's purpose of adding far more members to his family. If we look at Genesis' account of creation we find sets of animals made after 'their kind.' In Genesis 1:26 we find God made man after his OWN kind, after his image and likeness.
John the apostle fully understood why God made man in the first place.
"What glorious love the Father has given to us, that we should be called the children of God! . . . and it has not yet been revealed what we shall be . . . we shall be like Him." (1John 3:1-2, HBFV)
Jesus Christ came to the earth to live a perfect life, die for our sins, and be resurrected in order to make possible God's great goal for humans.
The trinity doctrine is one of many false doctrines of the Roman Catholic Church, which was subsequently adopted by most of her Protestant daughters throughout history. The Holy Spirit is the power through which he begets us as his dear children. It is decidedly not a person or part of a Trinity-based Godhead. Rather it is the power by which God the Father and Jesus Christ through which they accomplish their will.
