“Whether or not Descartes was a doctrinally correct, believing Christian is beside the point. He clearly had a Christian view of the universe.”
The predominant Christian view of the universe at that time was that the sun orbited the earth. That was NOT his view.

Even if you’re contention is true, about the prevailing “church” view regarding the sun and earth, the Christian view was that a rational God created a rational universe that can be studied and understood - obviously there was disagreement among Christians, just as there is among secular scientists today - you’re objection does not negate that fact.
