In his relatively short tenure, Pope Francis has been hard at work welcoming spiritual seekers into the Catholic Church. He’s refused to judge LGBT people, sought to integrate divorced couples, and extended priests’ ability to forgive abortion. But Francis’s wide arms have arguably never stretched further than a mass in 2014 when he suggested the church would baptize Martians.
“If—for example—tomorrow an expedition of Martians came … and one says, ‘But I want to be baptized!’ What would happen?” Pope Francis asked. “When the Lord shows us the way, who are we to say, ‘No, Lord, it is not prudent! No, let’s do it this way.’”
While playful, this odd scenario got at a serious question about just how far the church’s welcome can go. Should Christianity, the world’s largest religion, embrace all intelligent life? Even aliens? Granted, the arrival of green space creatures seeking salvation isn’t very likely. But the Pope’s lesson opens the door to the acceptance of another science-fiction stalwart, too—one that’s not so easily dismissed. Namely, hyper-intelligent machines.
While most theologians aren’t paying it much attention, some technologists are convinced that artificial intelligence is on an inevitable path toward autonomy. How far away this may be depends on whom you ask, but the trajectory raises some fundamental questions for Christianity—as well as religion broadly conceived, though for this article I’m going to stick to the faith tradition I know best. In fact, AI may be the greatest threat to Christian theology since Charles Darwin’s On the Origin of Species.
