Patristic Wisdom: Looking to the Twenty-Second Sunday after Pentecost

Now, brethren, concerning the coming of our Lord Jesus Christ and our gathering together to Him, we ask you, not to be soon shaken in mind or troubled, either by spirit or by word or by letter, as if from us, as though the day of Christ had come. Let no one deceive you by any means; for that Day will not come unless the falling away comes first, and the man of sin is revealed, the son of perdition, who opposes and exalts himself above all that is called God or that is worshiped, so that he sits as God in the temple of God, showing himself that he is God. Do you not remember that when I was still with you I told you these things? And now you know what is restraining, that he may be revealed in his own time. For the mystery of lawlessness is already at work; only He who now restrains will do so until He is taken out of the way. And then the lawless one will be revealed, whom the Lord will consume with the breath of His mouth and destroy with the brightness of His coming.… But we are bound to give thanks to God always for you, brethren beloved by the Lord, because God from the beginning chose you for salvation through sanctification by the Spirit and belief in the truth, to which He called you by our gospel, for the obtaining of the glory of our Lord Jesus Christ. Therefore, brethren, stand fast and hold the traditions which you were taught, whether by word or our epistle. Now may our Lord Jesus Christ Himself, and our God and Father, who has loved us and given us everlasting consolation and good hope by grace, comfort your hearts and establish you in every good word and work. (2 Thessalonians 2:1–8, 13–17)

Such is Paul's account. And we have reached the “falling away.” Men, that is, have fallen away from the true faith. Some proclaim the identity of Father and Son. Others dare to assert that one should believe Christ has come into existence out of nonexistence. Formerly heretics were quite evident, but now the church is full of masked heretics. For men have deserted the truth and want to have their ears tickled. Make a plausible case, and everyone is ready to listen to you. Talk of changing one's life, and everyone deserts you. The majority have fallen away from the sound doctrines and are readier to choose what is bad than to prefer what is good. So there you have the “falling away,” and the coming of the enemy is to be expected next. Meanwhile, he has begun to send out his forerunners here and there, so that the spoil may be prepared for him when he comes. Therefore, brothers, look to yourselves. Watch over your souls carefully.

The Antichrist just mentioned by Paul will come when the destined period of the Roman Empire has run its course and the subsequent end of the world is drawing near. Ten claimants to the empire will arise simultaneously, I suppose in different parts, but all wearing the purple at the same time. Antichrist will form an eleventh after them, having seized the imperial power by the use of magic arts. He will humble three of those who came to power before him and cause the remaining seven to be Caesars under him. At first he will feign mildness and will appear to be a learned and understanding man, with pretended prudence and kindness. Then he will take in the Jews, by making them suppose him to be their expected Messiah, by false signs and wonders produced by magical trickery. And afterwards his character will be written large in evil deeds of inhumanity and lawlessness of every kind, so as to outdo all wicked and godless men that were before him. He will display a murderous, most absolute, pitiless and unstable temper toward all people, but especially toward us Christians. He will act insolently for only three and a half years. Then he will be defeated by the second glorious coming from heaven of the only-begotten Son of God, our Lord and Savior Jesus, the true Christ. He will destroy Antichrist “with the spirit of his mouth” and commit him to the flames of hell.
