I've had this one in the back of my mind for a while, but it resurfaced today. Our congregation is having a Yard Sale at the building to support the youth group's summer mission trip. Someone asked me about it, and I can not for the life of me figure out what would be wrong with such an event.
I had spoken to the preacher at my last congregation about it after he mentioned it being wrong in a sermon to have a "church sponsored" yard sale. I asked him, "So if we can't have a church wide 'sanctioned' yard sale, can 5 or 10 familys get together to have a yard sale at someone's home and give that money to the church or a special mission trip fund?" He said, "sure." I said, "so what is the difference with the elders saying, 'we support this; bring your stuff; the teens will do the work and keep the proceeds for the mission trip.'?" The basic answer I got was, "It's just different." Sorry, that's not an answer that's a cop-out. I just can't see a difference, nor can I see a Biblical reason why a "Church santioned" yard sale is wrong?
The only example that I can think that could be remotely related in the Bible is the money changers and animal sales in the temple. And the problem there seems to me that people were lining their own pockets. I do not mean to step on toes (and I don't think it really applies), but this would more closely related to selling Mary Kay or Boy Scout Popcorn at Church.
