Eusebius of Caesarea
Catena Aurea · Lukasevangelium 17
And he said unto the disciples, The days will come, when ye shall desire to see one of the days of the Son of man, and ye shall not see it. And they shall say to you, See here; or, see there: go not after them, nor follow them. For as the lightning, that lighteneth out of the one part under heaven, shineth unto the other part under heaven; so shall also the Son of man be in his day. But first must he suffer many things, and be rejected of this generation.
As if he said, If at the coming of Antichrist, his fame shall be spread abroad, as though Christ had appeared, go not out, nor follow him. For it cannot be that He who was once seen on earth, shall any more dwell in the corners of the earth. It will therefore be he of whom we speak, not the true Christ. For this is the clear sign of the second coming of our Saviour, that suddenly the lustre of His coming shall fill the whole world; and so it follows, For as the lightning that lighteneth, &c. For He will not appear walking upon the earth, as any common man, but will illuminate our whole universe, manifesting to all men the radiance of His divinity.
