Early Church Fathers Quotes Against Polygamy
If, then, the teaching of the prophets and of Himself moves you, it is better for you to follow God than your imprudent and blind masters, who even till this time permit each man to have four or five wives; and if any one see a beautiful woman and desire to have her, they quote the doings of Jacob [called] Israel, and of the other patriarchs, and maintain that it is not wrong to do such things; for they are miserably ignorant in this matter.
Others, again, following upon Basilides and Carpocrates, have introduced promiscuous intercourse and a plurality of wives, and are indifferent about eating meats sacrificed to idols, maintaining that God does not greatly regard such matters

And thus, from the time of Abraham, the custom of marrying with sisters has ceased; and from the times of the prophets the contracting of marriage with several wives has been done away with; for we read, “Go not after your lusts, but refrain yourself front your appetites;”… Lest, however, we should seem prolix in collecting the testimonies of the prophets, let us again point out how chastity succeeded to marriage with one wife, taking away by degrees the lusts of the flesh, until it removed entirely the inclination for sexual intercourse engendered by habit.
“We do not indeed forbid the union of man and woman, blest by God as the seminary of the human race, and devised for the replenishment of the earth and the furnishing of the world and therefore permitted, yet singly. For Adam was the one husband of Eve, and Eve his one wife, one woman, one rib.
“That the good purpose of marriage, however, is better promoted by one husband with one wife, than by a husband with several wives, is shown plainly enough by the very first union of a married pair, which was made by the Divine Being Himself.”
