A husband and wife come together in order to lead their lives in common and to produce children, and that they should consider all their property to be common, and nothing private, not even their bodies … In marriage there must be complete companionship and concern for each other on the part of both husband and wife, in health and in sickness and at all times, because they entered upon the marriage for this reason as well as to produce offspring. When such caring for one another is perfect, and the married couple provide it for one another, and each strives to outdo the other, then this is marriage as it ought to be and deserving of emulation, since it is a noble union.
