ALL of the churches, Catholic churches, in our area followed the same practice. It was common practice across the nation.
SOME churches, I've discovered since being an adult, turned a blind eye to separated/divorced status. But many, if not most, did not. Not back in the 50's and 60's.
Then they lost so many people they changed their policy. But not in time for my family, which needed the church more than we ever needed it.
What we're attempting to explain to you is that that wasn't "policy". Priests or bishops who did that were making it up on their own.
My mothers reaction along with many others was that priest was a moron. (it takes all kinds you know)
My mothers decision was to sit in the same pew she always did. The priest only remained in that parish several years. She continued an additional 10 years.
