Diagram of the Trinity.
The Trinity as Shown in the Bible:
The Trinity can be derived from the following statements as found in the Bible:
1. There is only one God:
"Hear, O Israel: The LORD our God, the LORD is one."
Deuteronomy 6:4 (NIV)
2. The Father is God:
"God also said to Moses, Say to the Israelites, 'The LORD, the God of your fathers - the God of Abraham, the God of Isaac and the God of Jacob - has sent me to you.' This is my name forever, the name by which I am to be remembered from generation to generation."
3. Jesus Christ is God:
"Your attitude should be the same as that of Christ Jesus: Who, being in very nature God...."
4. The Holy Spirit is God:
"Then Peter said, 'Ananias, how is it that Satan has so filled your heart that you have lied to the Holy Spirit.... You have not lied to men but to God.'"
5. Father, Son and Holy Spirit are distinct:
"As Jesus was coming up out of the water, he saw heaven being torn open and the Spirit descending on him like a dove. And a voice came from heaven: 'You are my Son, whom I love; with you I am well pleased.'"
Mark 1: 10-11
"May 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
