That's nonsense. Given a formal theory, enumerate all finite strings in a language suitable for describing formal proofs in that theory. As each one appears, check to see whether it's a proof. Every proof in the theory will eventually appear.
If you meant to be talking about _efficient_ algorithms you should say so.
