There are walls of text on this topic in this thread. There are even charts supplied by Sea Breeze. Surely if the trinity doctrine was so cut and dry - even obvious, none of this would be necessary.
A lot of the scriptures 'supporting' the trinity are bible commentators saying what they believe to be the case, not quotes directly from jesus and these are mostly from John. Objectively speaking, that raises concerns.
The most basic example of this paradox is Jesus (the word) himself saying, ' the father is greater than I'. Then you have John, who says, 'the word was god'.
What about the quote from jesus at Matt 24:36? 'No one knows the day or hour but the father'? How can anyone possibly read that verse and decide it means that jesus = god, without serious mental gymnastics?
Im waiting for the 3000 word reply. Please include more charts - there can never be enough.
