Do many historians and Biblical researchers admit that the Trinity doctrine is not found in the Bible? Hopefully you can supply facts?

Yes, that's true.

That depends on what you mean by Trinity Doctrine. There is God, the Father of all Creation. There is Jesus Christ, His son. And the Holy Spirit. The Father is God (Duh). Jesus is God (John 3:16). And the Holy Spirit is God (Acts 5:3-4). They are not 3 separate Gods, but they are also not all the same. They are 3 separate persons who are all God. Again, not 3 gods. 1 God, 3 forms. This is what the Bible teaches.

The only people that dispute the trinity are those that are not Christian and/or those that belong to a non-Christian cult like LDS and Jehovah Witnesses.

While the term "trinity" is not found in the bible it's synonym "Godhead" is. Three times in the New Testament and speaks of Jesus being a man and also being deity.

Many other places in the bible the concept of the trinity is stated. MATTHEW 28:18-20 To Baptize in the name of the Father, Son, and Holy Spirit. And in may other places is scripture it says specifically that Jesus is the Lord and God JOHN 20:28, TITUS 2:13, JOHN 1:1-14.

The Apostles Paul, Thomas, John, and Peter all declare Jesus as God numerous times throughout their writings.

The Apostle Paul wrote In his apostolic benediction to the Corinthians, he underscored this same reality. He wrote, “The grace of the Lord Jesus Christ, and the love of God [the Father], and the fellowship of the Holy Spirit, be with you all” (2 Corinthians 13:14).

At Christ’s baptism, all three Persons were simultaneously active (Matthew 3:16–17), with the Son being baptized, the Spirit descending, and the Father speaking from Heaven. Jesus Himself prayed to the Father (cf. Matthew 6:9), taught that His will was distinct from His Father’s (Matthew 26:39), promised that He would ask the Father to send the Spirit (John 14:16), and asked the Father to glorify Him (John 17:5). These actions would not make sense unless the Father and the Son were two distinct Persons. Elsewhere in the New Testament, the Holy Spirit intercedes before the Father on behalf of believers (Romans 8:26), as does the Son, who is our Advocate (1 John 2:1). Again, the distinctness of each Person is in view.

Bottom line.....The trinity/Godhead is the most basic tenet of Christianity from the words of Jesus and his Apostles throughout the entire New Testament.

That is true. It's not in there. Neither is the word computer.

It’s true the word “trinity” is not in the Bible.

But the phrase “separation of church and state” is not in the Constitution. It was from a letter Jefferson wrote to the Danbury Baptists in 1801.

The universal expansion was predicted by Alexander Friedmann in 1922 and Georges Lemaître in 1927, long before Sir Frederick Hoyle coined the phrase “Big Bang” in the 1950’s.

Most ideas or doctrines usually exist before being given proper names.

Don't play dumb. The *term* Trinity didn't exist when the Bible was written, but Jesus told us to baptize in the name of Father, Son, and Holy Spirit = 3 = Trinity.

The word "Bible" isn't in the Bible either. Nobody's making an issue of that.

The Holy Spirit is our teacher

John 14:26 King James Version (KJV)

26 But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.

You have the mind of Christ...We all do.

Our Father, who art in heaven

I don't know of any legitimate scholars that would admit to such a claim. Sorry.
