If an unknown person bangs you in front of a Congregation, What will you do?

Answer 1

I don't know what you mean by "bang", but it sounds like your dignity was infringed on. I would go to that person after the meeting and tell them they did not have permission nor was it appreciated to do whatever they did. There's a verse in the Bible that helps with this kind of situation if I understand what you are saying,

1 Timothy 5:22 (King James Version)

22Lay hands suddenly on no man, neither be partaker of other men's sins: keep thyself pure.

This verse suggests that to do something that surprises a person is not acceptable.

Answer 2

Probably get dressed, then take up an offering.
