"excommunicate"
I really don't understand that term, other than to be a Catholic type thing? Would you like to discuss your former group?
LOOOooooong story.
In that church, which was a very close copy of the R Catholic church *, although they would not have admitted that, a true member of that church was a church-worker. I soloed in the home church and at the conventions, taught Sunday school, actually delivered a couple sermons when asked, was in some musical groups, played the flute in their orchestra, and so on. We were valued to the church according to our giving, our activities, and our personal connections.
So I had a daily job with a very large company in my area. That job was to drive from building to building, filling in at the front office while other receptionists took their lunch breaks. I had to wear a watch. Unfortunately, both I and my father are allergic to certain metals. All the wrist watches caused a very itchy, stinging rash.
This church did not allow us to wear jewelry that touched our skin, other than wrist watches, and they had just put out a little book with all their rules. I read through the little book and read it to my husband. We both agreed that since they didn't mention it, I should be allowed to wear a watch on a necklace, although necklaces ere banned otherwise. Not one to hide things, I thought nothing of wearing the new watch to church.
In the meantime, the pastor had told me I could not wear my wedding band in "his" church. He didn't mind if I wore it elsewhere, but he demanded that I take it off before entering. I don't do well with hiding stuff, but I seriously did my best to comply.
So there was a woman in the church who hated me and harassed me. She saw my watch and sicced the pastor on me, as was her weekly activity. He told me to remove it. Tired of their harassment, I told him I would not, and furthermore, I would not continue to remove my wedding band for him. As a result, he removed from me all my activities I did for the church, except for the meetings I organized in a retirement home, because no one else would do it. In other words, because I no longer had no work in the church, I was no longer a member. My membership was removed.
They didn't want me to come back, but my husband was a member, so in order to support him, I continued to come on Sunday mornings. No one had the nerve to tell me not to come back, so I did for a few months.
* It was like R. Catholic church in that it had a "pope" and powerful "priests," and a lot of other things emulated them; however, the church was a Pentecostal one. A quiet Pentecostal one, in that demonstrations were very unusual, except at the summer camps.
