This is interesting.
I'm wondering if it's just an American church culture phenomenon, and even more specifically, only certain denominations (Lutheran, Baptist, Methodist, Pentecostal? any others?) and, if it's only in the USA (do Canadian Lutheran churches hold potlucks?!)
I'd really love to hear from other people about what where they are located, what kind of church they attended/are in now, and what those churches do for congregation-wide fellowship.
Nothing like some good cultural lessons to go with that pot roast and vanilla wafer banana pudding!
