New Testament stance regarding adultery

Although the New Testament takes an even harsher stance regarding adultery than the Old Testament, the Christian Medieval literary tradition of courtly love (as evidenced in the poetic works of Marie de France) curiously seems to ennoble adultery. Keeping in mind that Marie de France is Christian, the paper should argue whether she is condemning or ennobling adultery in the assigned stories by quoting, analyzing, and citing the text. The thesis should be tested by devoting half of the paper to a serious consideration of the opposing position. The conclusion of the paper should attempt to revise the thesis in light of the arguments raised by the opposing position.
