I don't think the guy who assaulted the moneychangers in the temple, said it would be easier for a camel to go through the eye of a needle than a rich man to enter Heaven, and more than once told his followers to give everything they owned to the poor would be down with the prosperity gospel. Jesus would probably recite the parable of the talents, and tell you that if God gives you riches, it's to benefit the community and the poor, not for you to hoard as if you could take any of it with you.

But then again, one could argue that any interpretation of Christianity is legitimate, just as any interpretation of art or literature is legitimate. Prosperity gospel is no more out there than Gnosticism was, and only politics and culture determines what is and isn't canon. It isn't surprising that the prosperity gospel is a product of the capitalist and materialist US.

Still... it seems like a reach.

It’s not a scam — well, not all prosperity gospel preachers are scammers, but a few likely are. (Source: back in 2007/08 I was a true believer of a more mainstream Christianity and looked into this stuff in detail) The most charitable interpretation: some Christian traditions really hate wealth, and some see it as a blessing. You can find support for both in the Bible: Jesus is pretty anti-wealth, but then in Revelation 21 you have the New Jerusalem descending down from heaven, and God took the bling and turned it up to 11, and it’s the best thing ever.

Prosperity gospel churches are usually Pentecostal, which means they have a few special ways they like to interpret the Bible:

- They tend to take single Bible verses, often out of context, and use them as a foundation for entire novel lines of teaching. (This is opposed to reading and digesting whole stories)

- Those favorite Bible verses are emphasized, and passages that contradict them are downplayed. Once you decide that the Bible is pro-wealth, it can’t tell you it isn’t. (All Bible-believing Christians do this, whether they realize it or not. It’s called choosing a hermeneutic)

- There’s a culture that it’s common for the individual, especially the preacher, to hear directly from God. It’s pretty hard to argue with someone who claims the Holy Spirit told them something was true. (I always saw this as obviously problematic for a bunch of reasons)

When you put these together, you tend to get weird novel theologies. Other examples in the Pentecostal church include the personal prayer language (aka speaking in tongues) and faith healing.
