But, for most people, marriage has meaning beyond the legal sense. Marriage is also an agreement between the man and woman. Husband and wife take certain vows, to love one another, to cherish one another, and to stay together through sickness and health, for better and for worse. In most cases, this agreement includes sexual faithfulness, and a promise that each person will do what they can to make the other one happy. For some people, this agreement between man and woman takes the form of a covenant between not only the couple, but God as well. Thus, many marriages are performed within the rites of various churches and religious institutions.
