Question to my Christian friends about the Trinity...

If you tell someone a lie enough times will they believe it? These poor trinitarians.

I believe the doctrine of the Trinity was originally well-intentioned and developed as a way to avoid the stigma of being associated with polytheism. An "uneducated" Bible reader might conclude that Jesus prayed to a Father who was a separate being.

Bible Studies of a variety of the more difficult and controversial Bible subjects like the Trinity, Once saved always saved, Sabbath, Grace and the Law, death, hell and the 8th Day, and many more.

That was a ton of word salad to try to make something that is false to be true. He focuses on "is" with "He is the king," but the problem is he completely ignored the "the." He is "the" king implies there is only one king. If it was "He is king" then I would agree that there could be multiple kings. But "the" is an unambiguous grammatical article that infers a singular focus. But that focus can be plural (viz. "the kings" would obviously imply a singular group of multiple kings).

The common mistake of comparing God to us. This is idolatry 101 because we want to make a god in our own image.

Yeah. His explanation is valuable in explaining certain aspects of either the Mormon or Nicene versions of the Trinity. Note he says Christ's intercessory prayer isn't necessarily speaking of metaphysical oneness, & that's fine. But there's nothing in scripture that precludes it.
