“I confess that I cannot forbid a person to marry several wives, for it does not contradict the Scripture. If a man wishes to marry more than one wife he should be asked whether he is satisfied in his conscience that he may do so in accordance with the Word of God. In such a case the civil authority has nothing to do in the matter.”
Letter to Chancellor Gregory Bruck, January 13, 1524

“And, the case being thus, enough and more than enough answer has been made to the heretics, whether they be Manichees, or whosoever other that bring false charges against the Fathers of the Old Testament, on the subject of their having several wives, thinking this a proof whereby to convict them of incontinence: provided, that is, that they perceive, that that is no sin, which is committed neither against nature, in that they used those women not for wantonness, but for the begetting of children: nor against custom, forasmuch as such things were usually done at those times: nor against command, forasmuch as they were forbidden by no Law.” – St. Augustine, On the Good of Marriage (translated by Rev. C. L. Cornish M.A., of Exeter College, Oxford.), chp. 33.
