Kurtzahn, WELS-CLC-WELS, can help with this sticky subject.
Shrove Tuesday is a harmless way to use up the fat before Lent, not unlike the Jewish practice of using up leaven. "Shrove" comes from the practice of writing down one's confession of sins, the term being a corruption of the German word for write.
In the tiny, aging Church of the Lutheran Confession (sic), Circuit Pope Steve Kurtzahn managed to make pancakes sound felonious, a common problem with legalists. They invent their own commandments while ignoring the Ten Commandments. Thus a known adulterous, incestuous layman can destroy his family and be taken with utmost seriousness by the CLC (sic) clergy.
As the WELS Church Lady says, it is wise to stay away from them. In fact, Kurtzahn promoted himself back into the WELS after wrecking a number of CLC (sic) congregations.
Kurtzahn is now a regular on LutherQuest (sic), where the participants oscillate between truculent ignorance and psychosis.
