Question: The one(?) time that Jesus got angry was when there were merchants selling stuff in the temple. How is that different than the craft fairs or church bazaars where people are selling stuff at the church?
There were several times Jesus got angry (check out this article), but the thing that made him angry on this occasion was that as worshipers came to the temple for a proscribed or required festival and had to make sacrifices, it was much easier to buy an animal once you traveled to Jerusalem than to bring one from your town far away. But the leaders in Jerusalem determined that you could only pay for them with a certain temple coin, so that required making a monetary exchange. It was not a one-to-one exchange. I suppose you could say there was a money-changing fee attached, but it ended up being a tax and a hardship on many. Then, of course, the law of supply and demand caused the prices for animals, etc, there in the temple precinct to be inflated. Instead of helping people worship God it was making it difficult.
In other words, that is completely different from having a church bazaar or craft fair or a bookstore, for example. Now if a church were requiring you to buy a craft in order to participate in their worship service, that would make Jesus mad.
