No [one can] know when [a husband] and wife have sex except those two, for marriage in this world is a mystery for those married. If defiled marriage is hidden, how much more is undefiled marriage a true mystery! It is not fleshly but pure. It belongs not to desire but to will. It belongs not to darkness or night but to the day and the light. If marriage is exposed, it has become prostitution, and the bride plays the harlot not only if she is impregnated by another man but even if she slips out of her bedchamber and is seen. Let her show herself only to her father and her mother, the friend of the bridegroom, and the attendants of the bridegroom. They are allowed to enter the bridal chamber every day. But let the others yearn just to hear her voice and enjoy the fragrance of her ointment, and let them feed on the crumbs that fall from the table, like dogs. Bridegrooms and brides belong to the bridal chamber. No one can see a bridegroom or a bride except by becoming one.

(56) Therefore, O Man, look to it! [have a care] how you use the bestial Lust; it is (in itself) an Abomination before God, whether it be in the State of Wedlock, or out of it. But the right Love and Fidelity (in the Fear of God) covers it before the Countenance of God; and (through the Sun of the Virgin) it is regenerated to be a pure undefiled Creature again, in the Faith, if thy Confidence be in God.

(55) Therefore God established the State of Wedlock with Adam and Eve, and bound it fast with a strong Chain, in that he said; A Man shall leave Father and Mother, and cleave to his Wife, and they two shall be one Flesh. And God tolerates their as one Body and its Members, and must aim (in the Fear of God) at the Getting of Children; or else the Wantonness [or Lust] in itself (without that true Love of the State of Wedlock) is continually a bestial Lust, [Infection,] and Sin. And if you (in the State of Wedlock) seek nothing but the Lust and Lechery, then in such a Condition, thou art not a Jot better than a Beast, And do but consider it rightly, that without this, thou standest [already] in a bestial Birth [or Generation,] contrary to the first Creation, like all Beasts. For the holy Man in Adam was not predetermined to have propagated so, but in great modest Love out of himself.
