Apostolic Constitutions, Book VI 27

1Now if any persons keep to the Jewish customs and observances concerning the natural emission and nocturnal pollutions, and the lawful conjugal acts, let them tell us whether in those hours or days, when they undergo any such thing, they observe not to pray, or to touch a Bible, or to partake of the Eucharist? And if they own it to be so, it is plain they are void of the Holy Spirit, which always continues with the faithful. For concerning holy persons Solomon says: That every one may prepare himself, that so when he sleeps it may keep him, and when he arises it may talk with him. For if you think, O woman, when you are seven days in your separation, that you are void of the Holy Spirit, then if you should die suddenly you will depart void of the Spirit, and without assured hope in God; or else you must imagine that the Spirit always is inseparable from you, as not being in a place. But you stand in need of prayer and the Eucharist, and the coming of the Holy Ghost, as having been guilty of no fault in this matter. For neither lawful mixture, nor child-bearing, nor the menstrual purgation, nor nocturnal pollution, can defile the nature of a man, or separate the Holy Spirit from him. Nothing but impiety and unlawful practice can do that. For the Holy Spirit always abides with those that are possessed of it, so long as they are worthy; and those from whom it is departed, it leaves them desolate, and exposed to the wicked spirit. Now every man is filled either with the holy or with the unclean spirit; and it is not possible to avoid the one or the other, unless they can receive opposite spirits. For the Comforter hates every lie, and the devil hates all truth. But every one that is baptized agreeably to the truth is separated from the diabolical spirit, and is under the Holy Spirit; and the Holy Spirit remains with him so long as he is doing good, and fills him with wisdom and understanding, and suffers not the wicked spirit to approach him, but watches over his goings. You therefore, O woman, if, as you say, in the days of your separation you are void of the Holy Spirit, you are then filled with the unclean one; for by neglecting to pray and to read you will invite him to you, though he were unwilling. For this spirit, of all others, loves the ungrateful, the slothful, the careless, and the drowsy, since he himself by ingratitude was distempered with evil mind, and was thereby deprived by God his dignity; having rather chosen to be a devil than an archangel. Wherefore, O woman, eschew such vain words, and be ever mindful of God that created you, and pray to Him. For He is your Lord, and the Lord of the universe; and meditate in His laws without observing any such things, such as the natural purgation, lawful mixture, child-birth, a miscarriage, or a blemish of the body; since such observations are the vain inventions of foolish men, and such inventions as have no sense in them. Neither the burial of a man, nor a dead man's bone, nor a sepulchre, nor any particular sort of food, nor the nocturnal pollution, can defile the soul of man; but only impiety towards God, and transgression, and injustice towards one's neighbour; I mean rapine, violence, or if there be anything contrary to His righteousness, adultery or fornication. Wherefore, beloved, avoid and eschew such observations, for they are heathenish. For we do not abominate a dead man, as do they, seeing we hope that he will live again. Nor do we hate lawful mixture; for it is their practice to act impiously in such instances. For the conjunction of man and wife, if it be with righteousness, is agreeable to the mind of God. For He that made them at the beginning made them male and female; and He blessed them, and said, Increase and multiply, and fill the earth. If, therefore, the difference of sexes was made by the will of God for the generation of multitudes, then must the conjunction of male and female be also acceptable to His mind.
