I would suggest that Pastor you saw was a few eggs short of an omelet. No Lutheran teaching requires one to be willing to die for Martin Luther like one would for Christ. I find that just absolutely bizarre. If any Lutheran Pastor told me that I'd walk out too. We believe in the Augsburg Confessions, that, and Luther's Catechisms, are essential teachings of the Lutheran Faith - but that's no different than the Catholic Catechism except that we are not threatened with mortal sin and hellfire if we disagree with some of what's in it, etc.
Geez, what a disservice that Pastor did by saying something like that to you. That's just bizarre.
It happened in September, 1970, in a Lutheran Church in north St. Louis county where my husband was church organist at the time. Sorry I can’t remember the name of the place, or I’d tell you that, too.
Rob took a job with the Presbyterians, after that episode. Then the elders of that same Lutheran church paid a call on him, and told him he was no longer a member, shortly before our marriage that December.
