Obligatory Wisconsin Synod Lutheran Joke:
A man of faith dies without claiming allegience to any one “church”. So, St. Anthony is showing the various rooms in Heaven where he may spend eternity.
The first on is full of people drinking and playing bingo. The man says “This looks like fun. Who are they?” St. Anthony responds, “This is the Catholic room.”
The next room is full of people singing and dancing to some fantastic music. The man says, “This looks like fun. Who are they?” St Anthony responds, “This is the Black Baptist room.”
The next room is full of people sitting at long tables, looking out the corner of their eyes and whispering about their neighbors. The man says, “Who are these people who arent having any fun.” St Anthony responds, “These are the Wisconsin Synod Lutherans and they think they are the only ones up here.”
I posted my own experience of knowing two sisters in different Lutheran denominations on another thread:
The sister in the Wisconsin synod church would not pray (or allow the rest of her family to pray) with the Missouri synod relatives at family gatherings. It was pretty sick.
