Thaumaturgy is the capability of a magician or a saint to work magic or miracles. I guess that’s technically shorter than saying “the ability to do magic,” but I can’t imagine that that phrase comes up very often if ever, unless maybe, if you’re the Pope.
On a related note, a practitioner of thaumaturgy is a thaumaturge or thaumaturgist. But… but… but… didn’t we just get a definition saying that those people are called magicians or saints?
