They showed me the bill, it came in the mail. I saw the letter telling them they were no longer baptised. This happened in the late 70’s early 80’s.
Something here does not pass the smell test. There is simply no such thing as a “tithing bill,” and there never has been.
Think of it: by definition, tithing is one-tenth of the income. How would the Church “bill” for tithing with knowing the person’s income?
The LDS Church does occasionally excommunicate members; this only happens, though, to people who publicly preach against the Church, or who commit serious moral sin or serious crime. Not being a tithe payer has NEVER been a valid reason for excommunication.
I don’t know what they showed you, but I am highly skeptical.
It wasn't a tithing bill, there is no such thing.
