I'm especially interested in hearing from progressive Lutherans, but more conservative Lutherans are welcome to add their 2 cents.
In the interest of full disclosure, this is for a Sci-Fi story where the Episcopal Church, the United Methodist Church, and the ELCA merged into one church (the Evangelical Methodist Episcopal Church or EMEC) during the 24th Century; I want things that can be plausible remnants of Lutheran culture and practices.
Edit: Wow, thanks for all the info everyone! I'm saving this thread to my memories. I'm really greatful to everyone who contributed.
