Certainly, faith in secular progress can have religious aspects. It's important to distinguish between theism and religion. In the sociological sense, religion is whatever unites a group around a practice that's grounded in the taking of something to be sacred or of ultimate importance. The idol could be money, fame, power, sex, nature, art, the ego, drugs, or whatever. You'd have a tribal cult or a religion, depending on how widespread is the social mechanism.

But some will prefer not to draw that distinction and they'll say there's no religion without theism. Thus there could be no secular, civic religion. There could be atheistic ideologies, mob mentalities, or cults, but no atheistic religion. That's just a semantic question about how broadly the word should be defined.
