Marriage is a unique relationship between one man and one woman. Within that unique relationship we have the opportunity to serve one individual, living out the relationship we have with Christ. Husband are to love their wives as Christ loved the church and wives are to submit and respect their husbands. That doesn't define roles or hierarchy. Depend upon God and His Holy Spirit to carry out these roles. The husband and wife are to be controlled by the love of God. The result is a wonderful and satisfying relationship.
