Originally a comment by Gordon Willis on How different?
The major point is that the desire to learn about the world as it is in itself is not and cannot be the same as the desire to understand god’s creation. There is a fundamental difference which the words “learn more about the world around us” conceals. The one leads to knowledge regardless of any desire for human or personal “significance”, the other has as its goal an interpretation of the world related only to personal meaning (whatever “meaning” means). There is a search for knowledge and a search for meaning, and although these seem to go together there is a point at which the ways divide. Stedman seems to be trying to pretend that such a division can be slurred over, but it effectively destroys common ground except in the most trivial sense: we all “want to know” something or other about the world we live in.
We could suppose that we all find our meaning in response to what we know. For the atheist, “what we know” are observed and established facts, for the Christian “what we know” before anything else is the redemption of God’s fallen creation through the sufferings of Christ and how all things — whatever they are — work together for good to them that love the one supernal Fact. So an atheist might be outraged at the needless suffering and waste of women’s lives that is the result of Catholic policy, while the Christian will humbly submit to God for the outcome — whatever it is, and reject actual knowledge as a proper basis of action.
In this way, the desire to know about the world and to act on the basis of what is known would seem, from the atheist’s point-of-view, to be corrupted at the outset in the case of the believer. Perhaps you could say that for the atheist, meaning is what we make, but for the believer, meaning is truth. For the atheist, meaning emerges in personal life and is not mistaken for reality, whereas for the believer, meaning is something prior to what exists and is imposed upon it and ultimately revealed by the divine fiat.
we’re all trying to construct meaningful lives
Well, not really, not if, for some of us, the meaning is already granted. We atheists might be doing that, but the Christians’ task is to learn obedience. Stedman is like a blind man trying to blind people so that he can lead them. He wishes us to assume that we’re all the same really. No, we are not, and we will never agree; our only common ground is our humanity, and we can’t even agree on what that means.
