So he wasn't LCMS at the time he preached only Lutherans in heaven? Since that obviously isn't a doctrinal position of the LCMS. I am not a pastor.
I would doubt he ever said the words "Only Lutherans are in Heaven" I was talking about my attitude that I am sure, at my young age, was influenced by his teaching. Obviously you know how proud we LCMS members are about our doctrine. SNL's Dana Carvey grew up LCMS and it inspired his character the self righteous church lady.
I am not bashing any of my Pastors. God put them all in my life and I am grateful for their teaching and Holy Spirit calling.
Now to my Pastor discussion. Reading Luther don't Pastors actually have much authority in a local parish. A sort of shepherd of the folk? I bring this up because The LCMS institution is be undermining this relationship in my experience.
