On the Antichrist (Second Excerpt):

Who then is the blessed man, that shall at that time devoutly witness for Christ? For I say that the Martyrs of that time excel all martyrs. For the Martyrs hitherto have wrestled with men only; but in the time of Antichrist they shall do battle with Satan in his own person. And former persecuting kings only put to death; they did not pretend to raise the dead, nor did they make false shows of signs and wonders. But in his time there shall be the evil inducement both of fear and of deceit, so that if it be possible the very elect shall be deceived. Let it never enter into the heart of any then alive to ask, "What did Christ more? For by what power does this man work these things? Were it not God's will, He would not have allowed them." The Apostle warns thee, and says beforehand, And for this cause God shall send them a working of error; (send, that is, shall allow to happen;) not that they might make excuse, but that they might be condemned(2). Wherefore? They, he says, who believed not the truth, that is, the true Christ, but had pleasure in unrighteousness, that is, in Antichrist. But as in the persecutions which happen from time to time, so also then God will permit these things, not because He wants power to hinder them, but because according to His wont He will through patience crown His own champions like as He did His Prophets and Apostles; to the end that having toiled for a little while they may inherit the eternal kingdom of heaven, according to that which Daniel says, And at that time thy people shall be delivered, every one that shall be found written in the book (manifestly, the book of life); and many of them that sleep in the dust of the earth shall awake, some to everlasting life, and same to shame and everlasting contempt; and they that be wise shall shine as the brightness of the firmament; and of the many righteous, as the stars for ever and ever.

Guard thyself then, O man; thou hast the signs of Antichrist; and remember them not only thyself, but impart them also freely to all. If thou hast a child according to the flesh, admonish him of this now; if thou hast begotten one through catechizing, put him also on his guard, lest he receive the false one as the True. For the mystery of iniquity doth already work. I fear these wars of the nations; I fear the schisms of the Churches; I fear the mutual hatred of the brethren. But enough on this subject; only God forbid that it should be fulfilled in our days; nevertheless, let us be on our guard. And thus much concerning Antichrist.

But let us wait and look for the Lord's coming upon the clouds from heaven. Then shall Angelic trumpets sound; the dead in Christ shall rise first,--the godly persons who are alive shall be caught up in the clouds, receiving as the reward of their labours more than human honour, inasmuch as theirs was a more than human strife; according as the Apostle Paul writes, saying, For the Lord Himself shall descend from heaven with a shout, with the voice of the Archangel, and with the trump of God: and the dead in Christ shall rise first. Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air; and so shall we ever be with the Lord.
