I think most biblical christians would agree with this video, yet I think changing the habit of calling a church building "a church" or "going to church" would be a hard habit to change after all these years. But it would probably be a more exact/correct term and teaching tool for new or non christians to learn by.
I think a christian that is forced to live among many non-christians...like Brother Yun had to, may say, getting this exact would be important. Unfortunately, for those that live in a christian community and have not seen a lot of this darkness, of the lack of God's Word in the world, seem to pooh pooh the big deal about all of this...after all they know what they are talking about when they say it to each other. Not saying it's right...it's just how it seems to be.
