The first quote is from Justin who is accusing the Jews of his time of being polygamists. He was, of course, against, as has most Christian theologians, well…. until Luther who allowed it and a few other things which would just blow the mind of the modern fundamentalist who quotes Luther.
“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 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. For, as I before said, certain dispensations of weighty mysteries were accomplished in each act of this sort. For in the marriages of Jacob I shall mention what dispensation and prophecy were accomplished, in order that you may thereby know that your teachers never looked at the divine motive which prompted each act, but only at the grovelling and corrupting passions. Attend therefore to what I say. The marriages of Jacob were types of that which Christ was about to accomplish. For it was not lawful for Jacob to marry two sisters at once. And he serves Laban for the daughters; and being deceived in the younger, he again served seven years. Now Leah is your people and synagogue; but Rachel is our Church. And for these, and for the servants in both, Christ even now serves. For while Noah gave to the two sons the seed of the third as servants, now on the other hand Christ has come to restore both the free sons and the servants amongst them, conferring the same honour on all of them who keep His commandments; even as the children of the free women and the children of the bond women born to Jacob were all sons, and equal in dignity. And it was foretold what each should be according to rank and according to fore-knowledge. Jacob served Laban for speckled and many-spotted sheep; and Christ served, even to the slavery of the cross, for the various and many-formed races of mankind, acquiring them by the blood and mystery of the cross. Leah was weak-eyed; for the eyes of your souls are excessively weak. Rachel stole the gods of Laban, and has hid them to this day; and we have lost our paternal and material gods. Jacob was hated for all time by his brother; and we now, and our Lord Himself, are hated by you and by all men, though we are brothers by nature. Jacob was called Israel; and Israel has been demonstrated to be the Christ, who is, and is called, Jesus.
THE THIRD CANONICAL EPISTLE OF OUR HOLY FATHER BASIL, ARCHBISHOP OF CAESAREA IN CAPPADOCIA TO AMPHILOCHIUS, BISHOP OF ICONIUM
CANON LXXX. The Fathers say nothing of polygamy as being beastly, and a thing unagreeable to human nature. To us it appears a greater sin than fornication: Let therefore such be liable to the canons, viz.: after they have been mourners one year–let them be prostrators three years–and then be received,
