John Chrysostom
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.
When the Lord had finished all that related to Jerusalem, He came in the rest to His own coming, and gives them signs thereof, useful not for them only, but for us and for all who shall be after us. As above, the Evangelist said, In those days came John the Baptist, (Mat. 3:1.) not implying immediately after what had gone before, but thirty years after; so here, when He says Then, He passes over the whole interval of time between the taking of Jerusalem and the beginnings of the consummation of the world. Among the signs which He gives of His second coming He certifies them concerning the place, and the deceivers. For it shall not be then as at His former coming, when He appeared in Bethlehem, in a corner of the world, unknown of any; but He shall come openly so as not to need any to announce His approach, wherefore, If any man shall say unto you, Lo, here is Christ, or there, believe not.
