The information flow around the internet is just one more of many selection pressures on religions. Those that cannot adapt to it may go extinct or withdraw from contact. Most will ignore it and survive in persons not exposed to such widespread and rapid communication. Unlike science, religion does not require intelligence, equipment or substantial infrastructure to survive and grow. It has proved itself resilient and persistent over millennia and I don't expect it to wither in my lifetime. I wouldn't be surprised to see new versions specifically tuned to the internet and its users spring up and flourish.
So how, exactly, does God know that She's NOT a brain in a vat?
