Eusebius of Caesarea — as excerpted in the Catena Aurea on Luke 17:22-25

“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.”
