thaumaturgy

Thaumaturgy (from the Greek words , meaning "miracle" or "marvel" and , meaning "work") is the capability of a magician or a saint to work magic or miracles. Isaac Bonewits defined thaumaturgy as "The use of magic for nonreligious purposes; the art and science of 'wonder working;' using magic to actually change things in the physical world." It is sometimes translated into English as wonderworking. A practitioner of thaumaturgy is a thaumaturge, thaumaturgist or miracle-worker.
