^" are not to be compared to the holy women then, even when they married. Marriage itself indeed in all nations is for the same cause of begetting sons, and of what character soever these may be afterward, yet was marriage for this purpose instituted, that they may be born in due and honest order. But men, who contain not, as it were ascend unto marriage by a step of honesty: but they, who without doubt would contain, if the purpose of that time had allowed this, in a certain measure descended unto marriage by a step of piety. And, on this account, although the marriages of both, so far as they are marriages, in that they are for the sake of begetting, are equally good, yet these men when married are not to be compared with those men as married. For these have, what is allowed them by the way of leave, on account of the honesty of marriage, although it pertain not to marriage; that is, the advance which goes beyond the necessity of begetting, which they had not. But neither can these, if haply there be now any found, who neither seek, nor desire, in marriage any thing, save that wherefore marriage was instituted, be made equal to those men. For in these the very desire of sons is carnal, but in those it was spiritual, in that it was suited to the sacrament of that time. Forsooth now no one who is made perfect in piety seeks to have sons, save after a spiritual sense; but then it was the work of piety itself to beget sons even after a carnal sense: in that the begetting of that people was fraught with tidings of things to come, and pertained unto the prophetic dispensation.
 1 Cor. vii.9 c20. And on this account, not, so as it was allowed one man to have even several wives, was it allowed one female to have several husbands, not even for the sake of a family, in case it should happen that the woman could bear, the man could not beget. For by a secret law of nature things that stand chief love to be singular; but what are subject are set under, not only one under one, but, if the system of nature or society allow, even several under one, not without becoming beauty. For neither hath one slave so several masters, in the way that several slaves have one master. Thus we read not that any of the holy women served two or more living husbands: but we read that many females served one husband, when the social state  of that nation allowed it, and the purpose of the time persuaded to it: for neither is it contrary to the nature of marriage. For several females can conceive from one man: but one female cannot from several, (such is the power of things principal:) as many souls are rightly made subject unto one God. And on this account there is no True God of souls, save One: but one soul by means of many false gods may commit fornication, but not be made fruitful.
 Societas c21. But since out of many souls there shall be hereafter one City of such as have one soul and one heart  towards God; which perfection of our unity shall be hereafter, after this sojourn in a strange land, wherein the thoughts of all shall neither be hidden one from another, nor shall be in any matter opposed one to another; on this account the Sacrament of marriage of our time hath been so reduced to one man and one wife, as that it is not lawful to ordain any as a steward of the Church, save the husband of one wife.  And this they have understood more acutely who have been of opinion, that neither is he to be ordained,  who as a catechumen or as a heathen  had a second wife. For it is a matter of sacrament, not of sin. For in baptism all sins are put away. But he who said, "If thou shall have taken a wife, thou hast not sinned; and if a virgin shall have been married, she sinneth not:"  and, "Let her do what she will, she sinneth not, if she be married," hath made it plain enough that marriage is no sin. But on account of the sanctity of the Sacrament, as a female, although it be as a catechumen that she hath suffered violence, cannot after Baptism be consecrated among the virgins of God: so there was no absurdity in supposing of him who had exceeded the number of one wife, not that he had committed any sin, but that he had lost a certain prescript rule  of a sacrament necessary not unto desert of good life, but unto the seal of ecclesiastic ordination; and thus, as the many wives of the old Fathers signified our future Churches out of all nations made subject unto one husband, Christ: so our chief-priest,  the husband of one wife, signifies unity out of all nations, made subject unto one husband, Christ: which shall then be perfected, when He shall have unveiled the hidden things of darkness,  and shall have made manifest the thoughts of the heart, that then each may have praise from God. But now there are manifest, there are hidden, dissensions, even where charity is safe between those, who shall be hereafter one, and in one; which shall then certainly have no existence. As therefore the Sacrament of marriage with several of that time signified the multitude that should be hereafter made subject unto God in all nations of the earth, so the Sacrament of marriage with one of our times signifies the unity of us all made subject to God, which shall be hereafter in one Heavenly City. Therefore as to serve two or more, so to pass over from a living husband into marriage with another, was neither lawful then, nor is it lawful now, nor will it ever be lawful. Forsooth to apostatise from the One God, and to go into adulterous superstition of another, is ever an evil. Therefore not even for the sake of a more numerous family did our Saints do, what the Roman Cato is said to have done,  to give up his wife, during his own life, to fill even another's house with sons. Forsooth in the marriage of one woman the sanctity of the Sacrament is of more avail than the fruitfulness of the womb.
