You will not find the term “trinity” in the Bible. It is not used. It is a term that was coined to explain a paradox. You see, the Bible clearly states there is one God.
(Deuteronomy 6:4 KJV) Hear, O Israel: The LORD our God is one LORD:You cannot argue with this because it is so clear. At the same time you can find Bible verses that teach that the Father is God, that Jesus is God, and that the Holy Spirit is God. Then you have them talking to each other and being separate. It is confusing. It is clear. It is a paradox. It is the trinity.
