Jesus does, however, say that marriage is sacred and that remarriage after divorce is adultury. Many churches which profess a belief in the Bible as the inerrant Word of God are in disobedience to this direct commandment of Jesus.
For a divorced and remarried person, this can be one of the most difficult biblical principles to understand - that Jesus identifies remarriage as adultery. Particularly so when not learned along with the principles of repentance and forgiveness.
