New Testament Teaching about Marriage.

The New Testament does not contradict the teachings about marriage in the Old Testament. Most marriage teaching in the New Testament comes from Jesus and the apostle Paul.
Jesus' first miracle occurred in Cana in Galilee when He and His disciples were attending a wedding (John 2:1-11). Our Lord gave His blessing and sanction to the institution of marriage.
On another occasion, when Jesus was asked about marriage and divorce, He quoted two passages from Genesis. "Have you not read that He who made them at the beginning 'made them male and female,' and said, '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" (Gen 1:27; 2:24; 5:2; Matt 19:4-6). He taught that marriage was the joining together of two people so they become "one flesh." Not only did God acknowledge the marriage; He also joined the couple.
The church at Corinth struggled over a number of issues, including the proper view of marriage. In response to their questions, Paul gave an answer about marriage. From His answer, it seems that three faulty ideas about marriage were prominent among some believers in the church. The first was that marriage was absolutely necessary in order to be a Christian; another was that celibacy was superior to marriage; the third was that when a person became a Christian, all existing relationships such as marriage were dissolved. When chapter 7 of 1 Corinthians is read with that as background, the following teaching emerges.
First, Paul stated that celibacy is an acceptable lifestyle for a Christian, not all people need to marry. In fact, Paul declared that he himself preferred not to marry. However, the single life can be lived for God's glory only if God has given the gift of single hood. If one does not have that gift, he should marry. And Paul expected most people to marry.
Next, Paul spoke to the problem faced by a Christian believer whose spouse does not believe. He reasoned that if the unbelieving partner is willing to live with the Christian, then the Christian should not dissolve the marriage. Remaining with the unbelieving partner could result in his or her salvation (1 Cor 7:14).
In his letter to the Ephesians, Paul showed how a marriage relationship can best function. First, he said, "Wives, submit to your husbands, as to the Lord" (Eph 5:22). The model for the wife's submission is the church, which is subject to Christ (Eph 5:24). Second, husbands are to love their wives. The role that the husband plays is outlined by Jesus Christ, who loved His bride, the church, so much that He died for her (Eph 5:25).
