" Paul does not seem to share the conviction expressed in the Damascus Document and in Luke 16:18 that all remarriage is adulterous. As we have seen, he is startlingly unconcerned about traditional conceptions of purity and defilement (conceptions that provide the underlying Levitical warrants for the prohibition of remarriage). For him, what matters most is freedom to serve the Lord with “unhindered devotion” (v. 35) and to experience the eschatological peace of the people of God (v. 15). "
