Aussie-
You're right, you didn't quote the story. My fault. But that wasn't my point (and by the way I didn't quote it either). The point of the woman story was that Jesus didn't condemn giving money to the temple (or church or whatever) but rather he approved it when it came from pure motives. And Jesus driving people out of the temple may have indirectly resulted from the Roman commercialism but it was more directly because of the undermining of the sacrificial system and the importance of the role of the temple (the place where God dwells).
And I never tried to convince anyone of the purity of those ministries. I am not gonna make a judgement on enyart's ministries or anything else, but like you (and Christ too I'm sure) I am disgusted by the greed of many in the church. But keep in mind, we wouldn't be Christians if we were perfect. It's not some holiness club, we are Christians precisely because we are aware of how imperfect we are. No, that doesn't mean they (or I) have an excuse to do whatever we want. But it is the recognition that we cannot meet God's standard on our own and that we need a savior. That is why we belong to Christ. After all, the Protestant Reformation began partially out of the greed of the Catholic Church in selling indulgences ("when a coin in the coffer rings, a soul from purgatory springs" -Johann Tetzel). Things like this sicken me. I despise to see the name of my Lord used as a business advertisement. Another thing to remember is that oftentimes what is called the Christian church is not at all Christian, it is just another political organization identifying themselves by that label in order to gain power.
Showing you those sites was not to say that you have no point or that those organizations are not corrupt, it was to simply show the fallacy of your universal assumptions.
Don't dismiss Christ because of the actions of those who claim to be his followers. Look at the first hand accounts of him and his resurrection. If the resurrection happened all of existence hangs around it, if not then it means nothing and we (Christians) are all wasting our lives (as you think probably). But the evidence is there, ask "God" to show you. Don't close your mind to it. Give Him a chance. If you do, you'll be amazed.
