The adversary will sit in the temple of Jerusalem, in order to show himself as Christ, he will demand that those who are captivated by him should worship him as Christ. The Antichrist will demand worship as if he were God.
God will allow persecution from the Antichrist not because He cannot stop it, but because He desires, as usual, His strugglers to be crowned, and for this reason, the reverent ones among the living will be taken up into the clouds, receiving, as a reward of honor, that which is higher than any man.
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.
Having filled himself with pride, the Antichrist will begin to set himself up and glorify himself as God, belching forth slander against Christ. He will do this so openly that he will command that all those who do not want to serve him as God be killed.
He shall be known by his crimes of inhumanity and lawlessness, so as to outdo all unrighteous and ungodly men who have gone before him; displaying against all men, but especially against us Christians, a spirit murderous and most cruel, merciless and crafty.
The Antichrist will not only pronounce himself highest of the false gods, but will sit in the Temple of God, as if he were God ... the Jews, who did not want to believe in the Lord, as though He were an adversary to God, will believe in the Antichrist who will pronounce himself to be the god of all.
Let not us who would be Christians expect anything else than to be crucified...for to be Christian is to be crucified in this time and in any time since Christ came for the first time. His life is the example and warning to us all. We must be crucified personally, mystically; for through crucifixion is the only path to resurrection, if we would rise with Christ, we must be humbled with him even to the ultimate humiliation, being devoured and spit forth by the uncomprehending world...we must be crucified outwardly in the eyes of the world, for Christ’s kingdom is not of this world and the world cannot bear it, even a single representative, even for the single moment. The world can only accept Antichrist now or at any time.
If you have received from God the gift of knowledge, however limited, beware of neglecting charity and temperance. They are virtues which radically purify the soul from passions and so open the way of knowledge continually.
And the opinion, extremely popular in our times, that 'it's all the same which church you go to; after all, God is one' is in agreement with this tendency. Yes! God is one, but, you know, He also gave us one faith; He created one Church for us, not many different faiths and 'churches.' This is confirmed by the holy Apostle Paul when he says, 'One Lord, one faith, one baptism, one God and Father of all,' and so we Christians should form 'one body and one spirit,' as we are called to 'in one hope of our calling' (Eph. 4:4-6). If there is only one true faith and only one true Church, then as a consequence all other faiths and 'churches' are false, not true. How then can anyone say that all faiths and 'churches' are of equal value and that 'it is all the same which church you go to.' Therefore one can and must speak not of the ecumenical unification of everyone for the creation of some new Church, but only of the restoration of union between all who have fallen away and the one true Church of Christ to which Christ the Savior Himself gave the great and sure promise that 'the gates of hell will not prevail against it' (Matt. 16:18).
We firmly believe that the Church will never fall, will never waiver and will not be destroyed. For this is what Christ taught, by Whom the heavens were established and the earth was founded, and stands firmly as the Holy Spirit says” (Ps. 32:6). The Antichrist will lure to himself 'those who have a weak and feeble mind, will seduce and will tear them away from the living God.'
I say that martyrs of that time excel all martyrs, for martyrs hitherto have wrestled with men only, but in the time of the Antichrist they shall battle with Satan in his own person.
Many people will be found pleasing God, for whom it will be possible, in the mountains and in desert places, to save themselves by much prayer….for God, seeing their many tears and sincere faith, will have mercy on them, as a tender Father, and will keep them.
What is self-justification? - Self-justification is when a man denies his sin, as we see in the case of Adam, Eve, Cain and others who have sinned but, wishing to justify themselves, denied their sin.
If someone is judged worthy to receive the gift of knowledge but allows his heart to be full of bitterness or rancor or aversion to another, it is as if he had been struck in the eye by a thornbush. That is why knowledge is no good without charity.
For the Antichrist will come for the destruction of men, and to injure them, for what will he not then work? He will change and confound all things, both by his commandments and by the fear of him. He will be terrible in every way: by his power and by his unlawful commandments.’
