The word ‘Trinity’ is not in the Bible. 

I used to love saying that to Christians when I was an atheist with a radio talk show. It usually upset them, which caused them to get flustered on air. However, as I was to learn later, that does not mean the ‘Trinity’ is not in the Bible. In fact, our current study is an example of the ‘Trinity’ working together to bring about the ‘salvation’ of people in the world who ‘believe’ in Jesus Christ.
