This question is posed to Brandon E (though anyone else who chooses to address it is welcome to do so as well).
Brandon, there were controversies – or at the very least different viewpoints – about various issues in the New Testament. These included circumcision, acceptable foods, inclusion of the Gentiles, requirements of the Gentiles, marriage, the resurrection, and more. Not to be found among them, however, is any controversy or disagreement about the trinity. Why do you think that is so?
