Miracles are marvellous works; but that which is marvellous to one, may not be so to another. Sanctity may be feigned; and the visible felicities of this world are most often the work of God by natural and ordinary causes. And therefore no man can infallibly know by natural reason that another has had a supernatural revelation of God’s will, but only a belief; everyone, as the signs thereof shall appear greater or lesser, a firmer or a weaker belief.
