What was the foreign language they were chanting?

Made up words

Gibberish,really. The adults were doing it. It's is in 'Religulous' also(a man wears a suit in a desperate attempt to legitimise it).I forgot the technical term for it.It's supposedly the lord speaking through you in a tongue you don't understand.Some religious zealots practice for hours just to dumbfound you and throw you off balance, thinking there might actually be something behind it. There's not. Great question.
