There is a conservative approach to marriage that puts a great deal of stress on traditional gender roles. It says that the basic problem in marriage is that both husband and wife need to submit to their God-given functions, which are that husbands need to be the head of the family, and wives need to submit to their husbands. There is a lot of emphasis on the differences between men and women. The problem is that an overemphasis could encourage selfishness, especially on the part of the husband.
