Thank you, cofty, on posting that expose about Mother Theresa. It just goes to show us that most of what we know about the world around us are fabricated myths.
I haven't read Marx but I think I know what he meant when he said that religion was the opium of the masses. He meant that religion was what allowed the masses to be deadened to the injustices of the oppressor class.
I agree with that as far as Christianity and some other religions are concerned. People were simply told that they should not look to this world for their reward but should wait for their "pie in the sky when they die".
My disagreement is with the usage of the term religion in the general sense. I believe that religion becomes (not originates from) a projection of the civilization/society in which people live. To the extent that the society is oppressive so will their religions be.
Religion in general, though comes from a completely different place in the psyche of humanity.
Prehistoric cave paintings were religious in nature. They worshipped what they ate. In oppressive civilizations you worship what eats you, if you catch my drift. In the case of Christianity, it deadens you to the pain of being 'eaten'. Christianity is indeed an anaesthetic.
The religious impulse is simply a way to organize the world in the mind of the believer so that things make sense. That doesn't necessarily mean that the religion is rational but that the psyche, ego or whatever you call it, needs a framework of ideas to give the world meaning. It is basically a narrative, a story of stories, that we learn and recite to ourselves, whenever something perplexing needs explanation.
In it's original, uncorrupted form it's simply a way of making sense of life and the world.
