It may be tradition, but the cliche “I now pronounce you Husband and Wife” said by the officiating authority during a wedding rite is important. It kind of seals the marriage, making the relationship official and soon .to start a family.
What are the responsibilities of the husband and the wife in the family?
1 Corinthians 11:3 says “But I want you to understand that the head of every man is Christ, the head of a wife is her husband, and the head of Christ is God.” It explains that the husband is to assume leadership in the home. A role that should not be dictatorial, patronizing or superior attitude towards the wife. “Husbands, love your wives, just as Christ loved the church and give yourself up to her to make her holy, cleansing her by the washing with water through the Word.”
Wives, on the other hand, must submit to their husbands. Ephesians 5:22-24 – Wives, submit to your husbands as to the lord; for the husband is the head of the wife as Christ is the head of the church, his body, of which He is the Savior.
It is clear from the above verses that love and respect emanate from each responsibility. If these are present in every home, there will be no reason to break the marriage.
