XLV. But not yet perhaps is there formed upon your soul any writing good or bad; and you want to be written upon today, and formed by us unto perfection. Let us go within the cloud. Give me the tables of your heart; I will be your Moses, though this be a bold thing to say; I will write on them with the finger of God a new Decalogue. I will write on them a shorter method of salvation. And if there be any heretical or unreasoning beast, let him remain below, or he will run the risk of being stoned by the Word of truth. I will baptize you and make you a disciple in the Name of the Father and of the Son and of the Holy Ghost; and These Three have One common name, the Godhead. And you shall know, both by appearances and by words that you reject all ungodliness, and are united to all the Godhead. Believe that all that is in the world, both all that is seen and all that is unseen, was made out of nothing by God, and is governed by the Providence of its Creator, and will receive a change to a better state. Believe that evil has no substance or kingdom, either unoriginate or self-existent or created by God; but that it is our work, and the evil one's, and came upon us through our heedlessness, but not from our Creator. Believe that the Son of God, the Eternal Word, Who was begotten of the Father before all time and without body, was in these latter days for your sake made also Son of Man, born of the Virgin Mary ineffably and stainlessly (for nothing can be stained where God is, and by which salvation comes), in His own Person at once entire Man and perfect God, for the sake of the entire sufferer, that He may bestow salvation on your whole being, having destroyed the whole condemnation of your sins: impassible in His Godhead, passible in that which He assumed; as much Man for your sake as you are made God for His. Believe that for us sinners He was led to death; was crucified and buried, so far as to taste of death; and that He rose again the third day, and ascended into heaven, that He might take you with Him who were lying low; and that He will come again with His glorious Presence to judge the quick and the dead; no longer flesh, nor yet without a body, according to the laws which He alone knows of a more godlike body, that He may be seen by those who pierced Him, and on the other hand may remain as God without carnality. Receive besides this the Resurrection, the Judgment and the Reward according to the righteous scales of God; and believe that this will be Light to those whose mind is purified (that is, God— seen and known) proportionate to their degree of purity, which we call the Kingdom of heaven; but to those who suffer from blindness of their ruling faculty, darkness, that is estrangement from God, proportionate to their blindness here. Then, in the tenth place, work that which is good upon this foundation of dogma; for faith without works is dead, even as are works apart from faith. This is all that may be divulged of the Sacrament, and that is not forbidden to the ear of the many. The rest you shall learn within the Church by the grace of the Holy Trinity; and those matters you shall conceal within yourself, sealed and secure.
XLVI. But one thing more I preach unto you. The Station in which you shall presently stand after your Baptism before the Great Sanctuary is a foretype of the future glory. The Psalmody with which you will be received is a prelude to the Psalmody of Heaven; the lamps which you will kindle are a Sacrament of the illumination there with which we shall meet the Bridegroom, shining and virgin souls, with the lamps of our faith shining, not sleeping through our carelessness, that we may not miss Him that we look for if He come unexpectedly; nor yet unfed, and without oil, and destitute of good works, that we be not cast out of the Bridechamber. For I see how pitiable is such a case. He will come when the cry demands the meeting, and they who are prudent shall meet Him, with their light shining and its food abundant, but the others seeking for oil too late from those who possess it. And He will come with speed, and the former shall go in with Him, but the latter shall be shut out, having wasted in preparations the time of entrance; and they shall weep sore when all too late they learn the penalty of their slothfulness, when the Bride-chamber can no longer be entered by them for all their entreaties, for they have shut it against themselves by their sin, following in another fashion the example of those who missed the Wedding feast with which the good Father feasts the good Bridegroom; one on account of a newly wedded wife; another of a newly purchased field; another of a yoke of oxen; which he and they acquired to their misfortune, since for the sake of the little they lose the great. For none are there of the disdainful, nor of the slothful, nor of those who are clothed in filthy rags and not in the Wedding garment even though here they may have thought themselves worthy of wearing the bright robe there, and secretly intruded themselves, deceiving themselves with vain hopes. And then, What? When we have entered, then the Bridegroom knows what He will teach us, and how He will converse with the souls that have come in with Him. He will converse with them, I think in teaching things more perfect and more pure. Of which may we all, both Teachers and Taught, have share, in the Same Christ our Lord, to Whom be the Glory and the Empire, for ever and ever. Amen.
