> Who in their right mind would reject an offer of unlimited knowledge and worldly pleasures?
Most people. Unlimited knowledge? So no mystery to life. Unlimited worldly pleasures? Sound exhausting. There is a reason why hedonism hasn't taken over the world. Frankly, "unlimited knowledge and worldly pleasures" sounds like hell to me.
> Nowadays, rationalism and materialism have become the main objects of worship.
Nobody worships rationalism. Using reason to understand the world isn't a form of worship. It's the opposite of worship.
> But rationalism and materialism do not have answers to the existential questions and crises that humans face.
Existential crisis is a by-product of rationalism. When advances in science essentially debunked religious claims on nature and humanity, it removed the need for god ( aka "god is dead" - uh oh existential crisis ). It's hard to reconcile god making man out of dirt and evolution. To demand rationalism provide answers to the exstential crisis is irrational because existential crisis is the "answer" provided by rationalism.
> Similar to Christ saying that "man cannot live on bread alone", man cannot live on materialism alone - spiritual nourishment is a very real and necessary thing.
Man has, does and will live on materialism alone. Whether man can lead a more fulfilling life believing in religion is another story. Do kids who believe in santa claus lead better lives than those who do not. It's up for debate.
But rationalism can't have an answer for existential crisis. You cannot reason your way out of the existential crisis because reason and logic will lead you to it rather than religion. The only way out of existential crisis is to reject reason and logic to some degree.
Most people. Unlimited knowledge? So no mystery to life. Unlimited worldly pleasures? Sound exhausting. There is a reason why hedonism hasn't taken over the world. Frankly, "unlimited knowledge and worldly pleasures" sounds like hell to me.
