Funny thing is I am a LCMS Lutheran.
We tend to have a very high view of marriage also.
My bride is Catholic, and when we were about get engaged she went to her priest in Lincoln Nebraska and told him she was dating a LCMS boy.
He took her by the hand and laughed. Told her she needed to read the Bible more, and that “Your boyfriend will be very orthodox, but that is ok”.
Turned out the priest knew my pastor, and my pastor growing up .
Also they had only one Lutheran parochial school so they played in the CYO leagues so they didn't have to play the government schools.
