...but it's a good demonstration of 'I was a strange and you took me in'.
I disagree. Inviting them to one's house would be a demonstration of that. IMO people around here have a bit too care-free attitude towards choir-singing in a church choir. It's as sacral function as, say, serving in the altar. If we don't allow non-Orthodox altar servers it doesn't make sense to allow non-Orthodox choir members.
Post-liturgical coffee hours are a whole another thing though. Nothing wrong with that whoever is organizing them.
