How would major religions react to the aftermath of the film Armageddon? (spoilers)

They’d find a way to make money off of it somehow.

I don’t believe that people who praise god for a successful herioc act are talking about luck, and I don’t believe they’re excluding the credit for the deliberate actions of the hero. I believe they’re giving credit to a presumed sentient diety for causing the event to occur as it did, lock stock and barrel - just like they seem to be doing.

And not all acts of heroism require luck - reaching out and pulling a child out of the way of an oncoming bus is heroic, for example.

Of those who believe in an active God (which includes Christians, Jews, and Muslims), though there is a tension between God’s sovereignty on the one hand, and human beings’ free will and ability to affect the course of earthly events on the other, I think that the vast majority would tell you that something as major as the destruction of humanity would be under God’s control: it would happen if, and only if, God was ready for it to happen. Thus, if the world was not destroyed, it means that God did not intend that the world be destroyed at this time. So either God knew and intended all along that Bruce Willis & co. would save the Earth, or he had a Plan B.

That, as I said, is what I think the majority view would be. But, humans being the wacky irrational creatures that they are, there would be people who would have all sorts of weird perspectives on the thing.

Right. Sorry, Locrian, but Humanity being saved from a world-ending cataclysm by a human effort would NOT be a “gotcha” for most mainstream theologies. They’ve had thousands of years to make things fit; if they can handle theodicy, heroic human achievement is a walk. As begbert and others point out, they’ll credit the Divine Power with having used these men as his/her instruments. To repeat the example, folks speak of the “miracle on the Hudson”, as opposed to the “display of kick-ass-superstud airmanship and good structural buoyancy design on the Hudson”. It’s ingrained in the collective mind.
