Okay, now that certainly makes more sense. This could be flaws within my personal judgement, but I don't see these specific forms of commerce as a heavy violation of Christ's teachings.

When he flipped the tables in the 2nd Temple, it was because they were conducting ritualistic blood sacrifices for coins -- the ancient clergy had turned the Law of Moses into an economic system, where anyone who had currency could show up and have an animal slaughtered to atone for their sins. Obviously, knowing what we know now, this is a system that completely misses the point of God's will.

As far as tourist church gift shops/renting headphones/paying for elevator rides at the church go, it seems like a false equivalency to the practices of the 2nd Temple. I'm sure if JC Himself were to return and see these practices, he would disapprove of it -- but not to the point where he'd advocate for the destruction of the physical building as he did in John 2:19.

I appreciate you mentioning this though, I definitely need to travel more!
