In one easy step: Pray to the bull statue on Wall Street for money.
This kind of Fail should have been obvious. Even those who learned everything they needed to know about Christianity from watching Charleston Heston in Ben Hur and the Ten Commandments would know better than this. You could ask any agnostic, atheist, muslim, wiccan, or anyone on the street really whether this was in line with Christian teachings, and they'd all pass the test with flying colors.
I could only be more shocked if my Dad failed basic arithmetic.
While we're talking about Christians missing the point, here's another easy way to fail Christianity.
We have what is one of Christianity's most holy sites, and the six groups responsible for its keeping are too busy squabbling over it to fix the roof, build a fire exit or even take down a ladder.
Interactions between people are never simple, and interactions between six different groups are surely extremely complicated, particularly over something so important. However, one would hope and expect that Christians, of all people, would be able to practice the words of their namesake and get around normal human fallacies and work together. Alas.
At this point I wonder if it wouldn't be better if the whole thing collapsed (though the endless recriminations resulting from that would be unhelpful).
