Georgia, ulimately, yes, you have to honor his request if he’s requesting access and he’s a part of every group in the church. However, I would request to have a meeting with him FIRST so you can share what the purpose of your group is and why you think his presence could hinder the sharing of prayer requests, discussion, etc. I agree with you – it likely will.

Once you can figure out why he wants to join, you can find ways to address any concerns that he has.

Do you have a communications team at your church? What guidelines have been set in place regarding social media groups? It may be this highlights the need for some guidelines and a discussion with the elders and/or church staff. Once he understands your concerns and purpose, he may agree that his presence is not needed and could be disruptive.

Praying for wisdom for you!
