(selected from the saint's letters)
Vainly and erroneously you think and say that virtuous... Muslims will be saved, that is they will join intercourse with God! Vainly you consider the contrary notion a novelty, a brief error! No! Such is the eternal teaching of the true Church, both Old Testament and New. The Church has always confessed that there exists one means of salvation: the Redeemer! She has confessed that the most virtuous of the fallen really do descend to Hell. Did the righteous of the True Church, the illumined from whom shone the Holy Spirit, the prophets and wonderworkers, believers in the Redeemer's coming but with the demise of the anticipated coming of the Redeemer, descend to Hell so that, as you wish, the Muslims who neither recognize nor believe in the Redeemer receive, because they seem to you good people, that salvation which is delivered solely-- solely, I repeat to you, by means of -- belief in the Redeemer? -- Christians! Know Christ! -- Witness that you don't know Him, that you denied him in claiming the possibility of salvation without Him for some kind of virtue! Claiming the possibility of salvation without belief in Christ denies Him and, maybe not consciously, falls into the grave sin of blasphemy. "Therefore we conclude," says the Holy Apostle Paul, "that a man is justified by faith without the deeds of the law." (Romans 3:28) "Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference: for all have sinned, and come short of the glory of God; being justified freely by his grace through the redemption that is in Christ Jesus" (Romans 3:22-4). You will object: "The Holy Apostle James requires without fail good works; he teaches that 'faith, if it hath not works, is dead' (James 2:17)." Look again at what the Holy Apostle James requires. You will see that he, just like all God-inspired writers of Holy Scripture, requires the works of faith, and not the virtues of our fallen state! He requires living faith, confirmed by the deeds of the new man, and not the virtues of the fallen state, which are repugnant to faith. He cites the deeds of Patriarch Abraham, the work from which appeared the faith of a righteous man: this work consisted of offering as a sacrifice to God his only begotten son. To offer one's son as a sacrifice-- this is totally not a virtue according to human nature: it is a virtue as the fulfilment of the command of God, as a work of faith. Take a good look at the New Testament and in general all of Holy Scripture: you will find that it demands fulfilment of the commandments of God, that this fulfilment is called works, that from this fulfilment of God's commandments faith in God comes to life, as functioning; without works faith is dead, lacking any movement. And contrary to this, you will find that virtuous works of the fallen state, done out of feeling, blood, impulses or tenderheartedness-- are prohibited, repudiated! And namely for these virtues you like... the Muslims! To them, though it were repudiation of Christ, you want to give salvation.

You are blessed if you recognize the difference between the virtuous of the spirit and of the heart, between the virtuous peculiar solely to the New Adam, and virtuous which the old Adam is capable of joining: between the virtuous of the Gospel and the virtuous of our fallen state, the virtuous to whom are not strange idolaters, Muslims and all such people who shun the following of sacred Truth.
Letter No. 234
Faith is sacred and true only when it is faith in the sacred Truth, when it is faith which yields on the earth the human form of divine Truth, our Lord Jesus Christ. Any other faith, except faith in the sacred Truth, is superstition. The fruits of superstition are ruin. Such faith is condemned by God: it is the faith of idolaters in their idols, Muslims in their false prophet Mohammed and in the Qu'ran, heretics in their blasphemous dogmas and in their hereseiarchs, and rationalists in their fallen human intellect. With this faith will the Antichrist be believed by his followers.
Letter No. 236
There is no doubt that the action of spirits can be nourishing. But thus imparted to believe in them is impossible: if they occasionally speak even truth, it is in order to injure all the more reliably. At the present time their most important work is to let fall all that is true in the idea of God and of all that is divine and to glorify the idea of man in his fallen state, the more reason so to prepare the glorification of that man who extols himself above God according to the prophecy of the Holy Apostle Paul. Such an idea, which ruined men in paradise! Only it now uncoils more vastly. What Papism! What Mohammedism! This is only camouflage; this is particular activity. The Pope and Mohammed serve the fore-representation of the Antichrist...
