I go to a big friendly supportive church.
In the last 2 years we (as a family) have had a few issues with our teenagers which we have found really, really hard. For example, dd was struggling with gender identity and we didn't know how to support her. We have recently had something with ds too, which has been really hard to deal with, and doesn't paint him in a good light. Both are mid teens.
Dh and I made a firm decision that we could not share anything about dd and her issues without her consent, nor about ds and what was going on, without his.
We did speak to specific people in private for support, eg the pastoral support worker, who is also a good friend, and I confided in one close friend who also happens to be part of the church.
At a recent meeting about pastoral care, I raised this as an issue, the idea that parents can be struggling with things, but that there is an issue of confidentiality for the teens concerned, and so they might not be able to share about it. It was interesting to see that the room was split right in half.
Half felt that the parents should respect the confidentiality of the kids, and half felt that as a church family, it is OK to share things amongst the family. Those in the second camp just could NOT understand why you wouldn't share your stress with people at church, and that the kids should understand that we care and support each other in this way. In fact one of those people had recently asked me for prayer for her teen who is ill. She said 'he doesn't want us to tell everyone, but we told him the church family support each other this way' I was open mouthed. Your teenage son asked you NOT to share his personal details and you just rode roughshod over his wishes??!!
However as a result of that meeting, I know at least one of the leaders was very challenged by the issue of kids confidentiality. So I felt that was progress!
