Jhanic potential in Christians?

I was reading over at this post... https://buddhism.stackexchange.com/a/26834/13249 ...and saw this reply (quoted below) and wondered if I could get some elaboration. How is it a Christian could have jhanic potential? Are we talking about merit, morality, ethics, or spiritual health? Dispassion for material goods and wealth? Is this a common view held by Buddhist? "Also, at least in the West, many people with jhanic potential are Christians." ~ Dhammadhatu
