Jesus preached that the faithful should give up their wealth and worldly possessions and spend a humble existence in servitude of God. A church must have a certain amount of wealth in order to continue operating, serving its parishioners, and delivering the word to non-believers. However, churches of all denominations certainly amass wealth for its own sake. The canonical example of this is the Roman Catholic Church, whose ostentatious wealth I find shameful in the light of Jesus's teachings.
What does Christianity say about the wealth of a church? Its priests? Does wealth acquired in the name of the service of God have the same stigma as wealth acquired for ordinary reasons? Why or why not?
