Plus young earth (six day) creationism as an article of faith, and the ability of any LCMS member, anywhere, who gets pizzed off to bring "charges" against and LCMS pastor, anywhere.
A guy with a bee in his bonnet tried to defrock the Atlantic District President because he had dared to offer an overtly Christian prayer at an interfaith service at Yankee stadium a couple days after the 9-11-01 terrorist attacks.
Well, that guy was a Pastor (Preus I believe) and had some very valid concerns. Praying with other religions is not something we should do very often, if at all, in public. Many of my pastors growing up would either offer up the opening or closing prayer and not be on stage (or whatever) during the “group prayer”, or visit the family or families discretely and privately. One old pastor I knew said that such events were often more about the pastor’s ego rather than the family and victims’ souls.
Preus was, and still is, the south bound end of a north bound donkey, and the rest of the synod pretty much knows that. He has been trying to get elected as president for a few decades now, and manages to unite the opposition against him.
it is called syncretism and is unbiblical.
