I should add that the brute-force boxing in your original example (and my verbose method to do what I think you’re asking) seem awkward ways to accomplish boxing.

How about trying, say, the mdframed package? Or if all theorems are going to be similarly framed, then the ntheorem package with its framed option. Or the tcolorbox package. Or the thmtools package and then use a \declaretheorem with one of its options being shaded={rulecolor=black, bgcolor=white}?
