My mom, who is a grade school teacher, once mentioned that some of the teachers in her school had a group that got together for prayer each morning before school started. I told her I thought that was awesome, but she said she didn’t go. Confused, I asked her why not. She replied that she felt it was used somewhat as a gossip circle. In the past, other teachers had approached her about an issue within our extended family which had apparently been shared by one of the teachers who knew about it. That teacher had asked others to pray for our family, but went into detail about the situation (which, I thought, was not necessary.) And there was no reason, unless to let my mom know they were praying for us, that teachers should have approached her regarding the issue. She said it felt more like she was just being pumped for information, and that it had been brought up in the first place for less than stellar reasons. I think her experience can speak to yours, except she did not even ask for prayers from this group. There need to be clear boundaries, and perhaps in the future you could ask that the group pray for an anonymous intention.
