Christianity is the only major religion that makes this claim, that God the Father, God the Son, and God the Holy Spirit are each equally and eternally the one true God. It is admittedly difficult to comprehend, and yet is the very foundation of Christian truth.
Some people who reject the Trinity doctrine often claim that the word “Trinity” is not found in Scripture. Of course, there is no verse that says “God is three Persons” or “God is a Trinity.” This is all evident and true, but it proves nothing. There are many words and phrases that Christians use, which are not found in the Bible. For example, the word “Bible” is not found in the Bible.
When we say that the Father is God, the Son is God, and the Holy Spirit is God, they are not three gods but onlyone God. The Father is not the Son, the Son is not the Spirit, the Spirit is not the Father, but each is God individually and yet they are together the one true God of the Bible.
That is why Jesus said in John 10:30; "I and the Father are one.”(ESV)
The most difficult thing about the Christian concept of the Trinity is that there is no way to perfectly and completely understand it. The Trinity is a concept that is impossible for any human being to fully understand, let alone explain. God is infinitely greater than we are; therefore, we should not expect to be able to fully understand Him. The Bible teaches that the Father is God, that Jesus is God, and that the Holy Spirit is God.
The Bible also teaches that there is only one God. Though we can understand some facts about the relationship of the different Persons of the Trinity to one another, ultimately, it is incomprehensible to the human mind. However, this does not mean the Trinity is not true or that it is not based on the teachings of the Bible.
1 John 5:7 says; "For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one."(KJV)
Morealso, the New Testament does bring God (Father), the Son (Jesus Christ) and the Holy Spirit together in such a way as to strongly imply the Trinitarian nature of God. Three Scriptures are quoted below as a summary of the various other biblical passages that bring together the three Persons of the Godhead. One Scripture is from the Gospels, another is from the apostle Paul and a third is from the apostle Peter.
Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:(Matthew 28:19)(KJV).
The grace of the Lord Jesus Christ, and the love of God, and the communion of the Holy Ghost be with you all. Amen.(2 Corinthians 13:14)(KJV).
Elect according to the foreknowledge of God the Father, through sanctification of the Spirit, unto obedience and sprinkling of the blood of Jesus Christ: Grace unto you, and peace, be multiplied.(1 Peter 1:1-2)(KJV).
The individual members of the Trinity have different tasks.
The Father is the ultimate source or cause of the universe (1 Corinthians 8:6; Revelation 4:11); divine revelation (Revelation 1:1); salvation (John 3:16-17); and Jesus' human works (John 5:17; 14:10). The Father initiates all of these things.
The Son is the agent through whom the Father does the following works: the creation and maintenance of the universe (1 Corinthians 8:6; John 1:3; Colossians 1:16-17); divine revelation (John 1:1, 16:12-15; Matthew 11:27; Revelation 1:1); and salvation (2 Corinthians 5:19; Matthew 1:21; John 4:42). The Father does all these things through the Son, who functions as His agent.
The Holy Spirit is the means by whom the Father does the following works: creation and maintenance of the universe (Genesis 1:2; Job 26:13; Psalm 104:30); divine revelation (John 16:12-15; Ephesians 3:5; 2 Peter 1:21); salvation (John 3:6; Titus 3:5; 1 Peter 1:2); and Jesus' works (Isaiah 61:1; Acts 10:38). Thus, the Father does all these things by the power of the Holy Spirit.
Philippians 2:5-7 says; "Let this mind be in you, which was also in Christ Jesus: Who, being in the form of God, thought it not robbery to be equal with God:But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men."
Rather than attempting to fully define the Trinity with our finite human minds, we would be better served by focusing on the fact of God's greatness and His infinitely higher nature. “Oh, the depth of the riches of the wisdom and knowledge of God! How unsearchable his judgments, and his paths beyond tracing out! Who has known the mind of the Lord? Or who has been his counselor?” (Romans 11:33-34).
