It is. Because Trinitarian theology has been part of the Church since extremely early on. Did I ever claim it elucidates the entire Christian doctrine of the Trinity? No, I did not. You decided that me saying the Creeds were Trinitarian implied somehow that I thought the Apostle’s Creed explained everything Christians have traditionally believed about the Trinity and therefore you knew my entire understanding of was “abbreviated and unorthodox.” It is off-putting when you tell other people what they believe based on your own questionable leaps of logic.
That is excellent evidence that you are either confused about the doctrine of the Trinity or that you an an unorthodox definition of it.
This statement is excellent evidence that your reasoning process, here and elsewhere on this thread, is suspect.
