Adam, you refer to the incident of Jesus driving out money-changers. You write: "These money changers had a long standing tradition of providing a service, one that predated Jesus by a considerable amount of time."

What was really happening was that profiteering merchants had set up a kind of monopoly to take exorbitant profit from each and every person who wanted to honor God by obeying the Mosaic law. Under the pretense that Roman coins were unholy, they took the roman coins from people and sold them special temple coins with which to buy their animals for sacrifice. They had become "issuers of currency" with a monopolistic hold, taking advantage of all and sundry to line their own pockets. This God hates. God does not like people selling access to Himself, or attempting to do so. If coming to God is a matter of eternal life or death, you may understand why Jesus took steps to show God's anger at these corrupt and greedy practices.

Similarly, all churches that claim a monopoly on the grace of God and commercialise that "grace" by demanding offerings in exchange for the release of God's blessings provided at great cost by Jesus on the cross, these churches are an abomination to God.
