"...For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh. So then, they are no longer two but one flesh. Therefore what God has joined together, let not man separate." ~Matthew 19: 5-6
Most Christian denominations view marriage as a permanent and life long commitment between a man and woman. Christianity also views marriage as a holy sacrament and as a reflection of the relationship of Jesus Christ and the Church, in parallel to the Old Testament's teaching of the relationship between God and Israel.
