What does the Bible teach about the Trinity? Although the Bible does not use the word “Trinity,” it clearly teaches the doctrine of the Trinity throughout.
The Bible teaches that God exists as one God and three persons—Father, Son, and Holy Spirit—at the same time. The three persons are each fully God in the sense that they are co-eternal and co-equal.
16 And when Jesus was baptized, immediately he went up from the water, and behold, the heavens were opened to him, and he saw the Spirit of God descending like a dove and coming to rest on him; 17 and behold, a voice from heaven said, “This is my beloved Son, with whom I am well pleased.”Matthew 3:16-17
19 Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit,Matthew 28:19
14 The grace of the Lord Jesus Christ and the love of God and the fellowship of the Holy Spirit be with you all.2 Corinthians 13:14
These passages all refer to the three persons together, speaking of them all as being equal with one another.

57 So the Jews said to him, “You are not yet fifty years old, and have you seen Abraham?” 58 Jesus said to them, “Truly, truly, I say to you, before Abraham was, I am.”John 8:57-58
