John Chrysostom, on Heb 13:4

“Marriage honourable in all, and the bed undefiled. For fornicators and adulterers God will judge.”

“But let us see in what sense "Marriage is honorable in all and the bed undefiled." Because (he means) it preserves the believer in chastity. Here he also alludes to the Jews, because they accounted the woman after childbirth polluted: and "whosoever comes from the bed," it is said, "is not clean." Those things are not polluted which arise from nature O ungrateful and senseless Jew, but those which arise from choice. For if "marriage is honorable" and pure, why forsooth dost thou think that one is even polluted by it?”
