Matthew 24:27

Having told them how Antichrist cometh, as, for instance, that it will be in a place; He saith how Himself also cometh. How then doth He Himself come? "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 also will the eagles be gathered together." How then shineth the lightning? It needs not one to talk of it, it needs not a herald, but even to them that sit in houses, and to them in chambers it shows itself in an instant of time throughout the whole world. So shall that coming be, showing itself at once everywhere by reason of the shining forth of His glory. But He mentions also another sign, "where the carcase is, there also shall the eagles be;" meaning the multitude of the angels, of the martyrs, of all the saints.

Wherein He shows that His second coming shall be not in lowliness as His first, but in glory; and therefore it is folly to seek in places little and obscure for Him who is the Light of the whole world. (John 8:12.)

Or, when they allege secret and before unpublished Scriptures, in proof of their lie, they seem to say, Lo, the word of truth is in the desert. But when they produce canonical Scripture in which all Christians agree, they seem to say, Lo, the word of truth is in the chambers. Or wishing to point out such discourses as are altogether without Scripture, He said, If they shall say to you, Lo, he is in the secret chambers, believe it not. Truth is like the lightning that cometh out of the east, and shineth even unto the west. Or this may mean, that truth can be supported out of every passage of Scripture. The lightning of truth comes out of the east, that is, from the first beginnings of Christ, and shines throughout even to His passion, which is His setting; or from the very beginning of creation, to the last Scripture of the Apostles. Or, the east is the Law, the west is the end of the Law, and of John's prophecy. The Church alone neither takes away word or meaning from this lightning, nor adds aught to its prophecy. Or He means that we should give no heed to those who say, Lo, here is Christ, but show Him not in the Church, in which alone is the coming or the Son of Man, who said, Lo, I am with you always, even to the end of the world. (Mat. 28:20.)

The false prophets, of whom He had spoken above, shall say of Christ one while, Lo, He is in the desert, in order that they may cause men to wander astray; another while, Lo, He is in the secret chambers, that they may enthral men under the dominion of Antichrist. But the Lord declares Himself to be neither lurking in a remote corner, nor shut up to be visited singly, but that He shall be exhibited to the view of all, and in every place, As the lightning cometh out of the east, and shineth even unto the west, so shall the coming of the Son of Man be.

(Quæst. Ev. i. 38.) By the east and west, He signifies the whole world, throughout which the Church should be. In the same way as He said below, Hereafter shall ye see the Son of Man coming in the clouds of heaven, (Mat. 26:64.) so now He likens His coming to lightning, which uses to flash out of the clouds. When then the authority of the Church is set up clear and manifest throughout the whole world, He suitably warns His disciples that they should not believe schismatics and heretics. Each schism and heresy holds its own place, either occupying some important position in the earth, or ensnaring men's curiosity in obscure and remote conventicles. Lo, here is Christ, or lo, there, refers to some district or province of the earth; the secret chambers, or the desert, signify the obscure and lurking conventicles of heretics.
