He is not LCMS. Apparently he was educated at a non-Lutheran seminary and is part of a very fringe group that calls themselves Lutheran, specifically LMS-USA. My quick internet review suggest this group has at most three small congregations. Other than as click bait — it worked from me — I do not know why this person is covered. I hope it was not to create divisions.
That is evident in numerous ways. The church in San Antonio that he (supposedly) pastors is listed on the LCMS roster, however. Since the LCMS generally doesn't suffer fools well, I am sure he is on the synod radar.
