Does religion require a deity?

I am a Unitarian Universalist and while there are many Unitarians who believe in a god there are also many atheists among us – so I would say no.

Well, as a Buddhist (one of the religions mentioned in your link) I would obviously say no.

Einstein wrote quite a bit about his own religious feelings, which didn’t involve anything like the common conception of God:

“Common to all [primitive religions] is the anthropomorphic character of their conception of God. In general, only individuals of exceptional endowments, and exceptionally high-minded communities, rise to any considerable extent above this level. But there is a third stage of religious experience which belongs to all of them, even though it is rarely found in a pure form: I shall call it cosmic religious feeling.

It is very difficult to elucidate this feeling to anyone who is entirely without it, especially as there is no anthropomorphic conception of God corresponding to it. The individual feels the nothingness of human desires and aims and the sublimity and marvelous order which reveal themselves both in Nature and in the world of thought. He looks upon individual existence as a sort of prison and wants to experience the universe as a single significant whole.”

Not necessarily you can be a Buddhist who doesn’t believe in a deity.

The question sets you to thinking. For instance, what’s the relationship between the concepts of religion and worship? Here’s a scenario: An alien expedition clandestinely observes our society. After a year or so they choose a human (you) to quiz on a thing that puzzles them. If a church is considered a “house of worship”, they ask, why aren’t the banks exalted as such since the worship of money appears universal?
