God has ordained the family as the foundational institution of human society. It is composed of persons related to one another by marriage, blood or adoption.
Marriage is the uniting of one man and one woman in covenant commitment for a lifetime. ... The husband and wife are of equal worth before God, since both are created in God's image. A husband is to love his wife as Christ loved the church. He has the God-given responsibility to provide for, to protect, and to lead his family. A wife is to submit herself graciously to the servant leadership of her husband even as the church willingly submits to the headship of Christ. She, being in the image of God as is her husband and thus equal to him, has the God-given responsibility to respect her husband and to serve as his helper in managing the household and nurturing the next generation... Children, from the moment of conception, are a blessing and heritage from the Lord. Parents are to demonstrate to their children God's pattern for marriage.
