Mark 10:2-12
2Some Pharisees came and tested him by asking, "Is it lawful for a man to divorce his wife?" 3"What did Moses command you?" he replied. 4They said, "Moses permitted a man to write a certificate of divorce and send her away."
5"It was because your hearts were hard that Moses wrote you this law," Jesus replied. 6"But at the beginning of creation God 'made them male and female. 7'For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh. 8So they are no longer two, but one. 9Therefore what God has joined together, let man not separate." 10When they were in the house again, the disciples asked Jesus about this. 11He answered, "Anyone who divorces his wife and marries another woman commits adultery against her. 12And if she divorces her husband and marries another man, she commits adultery."
Ephesians 5:21-33
21Submit to one another out of reverence for Christ. 22Wives, submit to your husbands as to the Lord. 23For the husband is the head of the wife as Christ is the head of the church, his body, of which he is the Saviour. 24Now as the church submits to Christ, so also wives should submit to their husbands in everything. 25Husbands, love your wives, just as Christ loved the church and gave himself up for her 26to make her holy, cleansing her by the washing with water through the word, 27and to present her to himself as a radiant church, without stain or wrinkle or any other blemish, but holy and blameless. 28In this same way, husbands ought to love their wives as their own bodies. He who loves his wife loves himself. 29After all, no one ever hated his own body, but he feeds and cares for it, just as Christ does the church- 30for we are members of his body. 31"For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh." 32This is a profound mystery-but I am talking about Christ and the church. 33However, each one of you also must love his wife as he loves himself, and the wife must respect her husband.
1 Corinthians 7:1-16
1Now for the matters you wrote about: It is good for a man not to marry. 2But since there is so much immorality, each man should have his own wife, and each woman her own husband. 3The husband should fulfill his marital duty to his wife, and likewise the wife to her husband. 4The wife's body does not belong to her alone but also to her husband. In the same way, the husband's body does not belong to him alone but also to his wife. 5Do not deprive each other except by mutual consent and for a time, so that you may devote yourselves to prayer. Then come together again so that Satan will not tempt you because of your lack of self-control. 6I say this as a concession, not as a command. 7I wish that all men were as I am. But each man has his own gift from God; one has this gift, another has that. 8Now to the unmarried and the widows I say: It is good for them to stay unmarried, as I am. 9But if they cannot control themselves, they should marry, for it is better to marry than to burn with passion. 10To the married I give this command (not I, but the Lord): A wife must not separate from her husband. 11But if she does, she must remain unmarried or else be reconciled to her husband. And a husband must not divorce his wife. 12To the rest I say this (I, not the Lord): If any brother has a wife who is not a believer and she is willing to live with him, he must not divorce her. 13And if a woman has a husband who is not a believer and he is willing to live with her, she must not divorce him. 14For the unbelieving husband has been sanctified through his wife, and the unbelieving wife has been sanctified through her believing husband. Otherwise your children would be unclean, but as it is, they are holy. 15But if the unbeliever leaves, let him do so. A believing man or woman is not bound in such circumstances; God has called us to live in peace. 16How do you know, wife, whether you will save your husband? Or, how do you know, husband, whether you will save your wife?
Matthew 19:4-6
4"Haven't you read," he replied, "that at the beginning the Creator 'made them male and female, 5and said, 'For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh'? 6So they are no longer two, but one. Therefore what God has joined together, let man not separate."
Hebrews 13:4
4Marriage should be honoured by all, and the marriage bed kept pure, for God will judge the adulterer and all the sexually immoral.
Ephesians 5:22-33
22Wives, submit to your husbands as to the Lord. 23For the husband is the head of the wife as Christ is the head of the church, his body, of which he is the Saviour. 24Now as the church submits to Christ, so also wives should submit to their husbands in everything. 25Husbands, love your wives, just as Christ loved the church and gave himself up for her 26to make her holy, cleansing her by the washing with water through the word, 27and to present her to himself as a radiant church, without stain or wrinkle or any other blemish, but holy and blameless. 28In this same way, husbands ought to love their wives as their own bodies. He who loves his wife loves himself. 29After all, no one ever hated his own body, but he feeds and cares for it, just as Christ does the church- 30for we are members of his body. 31"For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh." 32This is a profound mystery-but I am talking about Christ and the church. 33However, each one of you also must love his wife as he loves himself, and the wife must respect her husband.
