Regarding the topic of Lutherans and Worship I commend to your reading these posts on the following blogs:
"Diversity in Lutheran Worship" (July 11, 2006) on http://fatherhollywood.blogspot.com
"Optional Orandi begets Proscribed Credendi" (June 17, 2006) on http://conversiaddominum.blogspot.com
Whether or not one agrees with use of the historic or traditional liturgy one can see the differences that confront us today in what passes as "worship." Hopefully, and unfortunately, we see that the differences are not only a matter of worship but also a matter of faith.
