Did you catch this fact?
**This feast became widespread in the West in the 11th century and was introduced into the Roman calendar in 1457 to commemorate the victory over Islam in Belgrade.**
Bump!
Yes, and that explains why the "Renewing Worship" project of the Evangelical Lutheran Church in America (ELCA) has dropped the optional observance of this feast on its traditional date August 6 (the Festival is always observed on the traditional Quinquagesima Sunday, the Sunday preceding Ash Wednesday as a bridge between Epiphany and Lent).
The leadership of the ELCA is bitterly opposed to the U.S. military in general and the war on terror in particular. Multicultural diversity is its highest virtue so, of course, any obeservance that might be offensive to Muslims must go.
