Augustine of Hippo
Catena Aurea · Markusevangelium 13
And then if any man shall say to you, Lo, here is Christ; or, lo, he is there; believe him not: For false Christs and false prophets shall rise, and shall shew signs and wonders, to seduce, if it were possible, even the elect. But take ye heed: behold, I have foretold you all things. But in those days, after that tribulation, the sun shall be darkened, and the moon shall not give her light, And the stars of heaven shall fall, and the powers that are in heaven shall be shaken. And then shall they see the Son of man coming in the clouds with great power and glory. And then shall he send his angels, and shall gather together his elect from the four winds, from the uttermost part of the earth to the uttermost part of heaven.
(de Civ. Dei, xx. 19) For then shall Satan be unchained, and work through Antichrist in all his power, wonderfully indeed, but falsely. But a doubt is often raised whether the Apostle said Signs and lying wonders, because he is to deceive mortal senses, by phantoms, so as to appear to do what he does not, or because those wonders themselves, even though true, are to turn men aside to lies, because they will not believe that any power but a Divine power could do them, being ignorant of the power of Satan, especially when he shall have received such power as he never had before. But for whichever reason it is said, they shall be deceived by those signs and wonders who deserve to be deceived.
