Thank you for your posting:
To which I would add:Although I am trinitarian, I believe more is said than necessary on this subject, a lot of it little more than speculation. Peter's confession was commended by Jesus. If we must know more than this to be saved, then most people aren't smart enough to make it, including perhaps all who post here. (Perhaps there is a test on judgement day where a correct explanation of the exact nature of the Trinity must be given to pass!)
How many of those who faithfully fill the pews on Sunday do you suppose could explain the Trinity? Perhaps simple faith in and faithfulness to our Lord isn't enough?
Isn't salvation by impeccability of doctrine another form of "works-righteousness"?
Shlamaa,
