this is so we don't derail the other thread talking about this!
i don't think we should call some churches 'mission churches' as it takes the focus away from the fact that we should all share our faith.
so far we don't have this concept in the uk, and i hope we don't go in this direction.
there is room for all of us to both help new immigrants who don't speak english (or the country's language, for european churches)
and to bring those in from outside who are missing the richness and depth of orthodox Christianity.
