Is anger a sin? In the Gospel at today’s Mass from Luke chapter 19, we hear a story that appears in all four gospels. It’s the story where Jesus became very angry when He entered the temple and found people selling things. Why did he get so angry? Not only because His Father’s house which was supposed to be a house of prayer was being turned into a marketplace, but also because poor people who were just trying to worship God, couldn’t do so because they were being given an unfair rate of exchange for the money they brought to pay the temple tax.
