655. What a miracle is

A miracle is what is done by the Lord, when there is something that concerns Himself, belief in Him, His Heaven, or the Church as a whole, which then passes through His Heaven, and is then carried out by spirits without any of their own cooperative power [entering into it]. This is a miracle, and is called "the finger of God" [Ex. 8:19, 31:18, Deut. 9:10, Luke 11:20].
