That's an extremely narrow, Judaeo-Christian view of religion.

You're right. But I wanted to reply on the same level as the OP.

I thought the OP's point was that phrases like "taking control over our stewardship of the planet" was a religious statement in that the only reason the concepts in it have any grounding is through the faith of the person saying them. That's not religion-specific.

I don't follow you on the jump from unfounded to religious. Not every statement which does not include a scientific footnote is religious in nature.

We're drifting into semantics here, but it boils down to whether you have to take something on faith or not. Taking anything without a "scientific footnote" as true relies on belief, because it cannot rely on proof. That makes it an article of faith, which is a synonym for religion in the sense I believe the OP used it.
