Catena Aurea · Matthäusevangelium 24
Then if any man shall say unto you, Lo, here is Christ, or there; believe it not. For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect. Behold, I have told you before. Wherefore if they shall say unto you, Behold, he is in the desert; go not forth: behold, he is in the secret chambers; believe it not. For as the lightning cometh out of the east, and shineth even unto the west; so shall also the coming of the Son of man be. For wheresoever the carcase is, there will the eagles be gathered together.
(Lib. 83 Quæst. q. 79.) Here the Lord forewarns us that even wicked men shall do some miracles which the saints cannot do, yet are they not therefore to be thought to have a higher place in the sight of God. For the Egyptian magi were not more acceptable to God than the people of Israel, because they could do what the Israelites could not; yet did Moses, by the power of God, work greater things. This gift is not bestowed on all the saints, lest the weak should be led astray by a most destructive error, supposing such powers to be higher gifts than those works of righteousness by which eternal life is secured. And though magi do the same miracles that the saints do, yet are they done with a different end, and through a different authority; for the one do them seeking the glory of God, the others seeking their own glory; these do them by some special compact or privilege1 granted to the Powers, within their sphere, those by the public dispensation and the command of Him to whom all creation is subject.f For it is one thing for the owner of a horse to be compelled to give it up to a soldier, another for him to hand it over to a purchaser, or to give or lend it to a friend; and as those evil soldiers, who are condemned by the imperial discipline, employ the imperial ensigns to terrify the owners of any property, and to extort from them what is not required by the public service; so some evil Christians, by means of the name of Christ, or by words or sacraments Christian, compel somewhat from the Powers; yet these, when thus at the bidding of evil men, they depart from their purpose, they depart in order to deceive men in whose wanderings they rejoice. It is one way then in which magi, another in which good Christians, another in which bad Christians, work miracles; the magi by a private compact, good Christians by the public righteousness, evil Christians by the signs of public righteousness. 1And we ought not to wonder at this when we believe not unreasonably that all that we see happen is wrought by the agency of the inferior powers of this air.
