“The real reason Charles Darwin distresses people, I would argue, is not that he stumbled on an argument against theism. No, the problem was that he replaced theism—replaced it with a construct more beautiful and majestic than any account of the Supreme Being outside the Book of Job, a construct that invites us to see every variety of life, from aphids to archbishops, zygotes to zoologists, as vibrant threads in an epic tapestry, its warp and woof stretching across the eons and back to the Precambrian ooze, the seminal sea-vents, the primordial clay-pits, or wherever it all began. An astonishing construct, a mind-boggling construct, a construct of which Jehovah is understandably and insanely jealous.”

Lectures on the Essence of Religion http://www.marxists.org/reference/archive/feuerbach/works/lectures/index.htm (1851)
Context: Religion is indeed essential to or innate in man, but … this is not the religion of theology or theism, not an actual belief in God, but solely the religion that expresses nothing other than man’s feeling of finiteness and dependency on nature. … I distinguish religion from theism, the belief in a being distinct from nature and man. … Today theism, theology, the belief in God have become so identified with religion that to have no God, to theological being, is considered synonymous with having no religion. But here we deal with the original elements of religion. It is theism, theology, that has wrenched man out of his relationship with the world, isolated him, made him into an arrogant self-centered being who exalts himself above nature. And it is only on this level that religion becomes identified with theology, with the belief in a being outside and above nature as the true God. Originally religion expressed nothing other than man’s feeling that he is an inseparable part of nature or the world.
