In some cultures, marriage is recommended or considered to be compulsory before pursuing any sexual activity.
When defined broadly, marriage is considered a cultural universal. Individuals may marry for several reasons, including legal, social, libidinal, emotional, financial, spiritual, and religious purposes.
Religious marriage recognizes and creates the rights and obligations intrinsic to matrimony before that religion.
Religious marriage is known variously as sacramental marriage in Catholicism, nikah in Islam, nissuin in Judaism, and various other names in other faith traditions, each with their own constraints as to what constitutes, and who can enter into, a valid religious marriage.
Some countries do not recognize locally performed religious marriage on its own, and require a separate civil marriage for official purposes.
Conversely, civil marriage does not exist in some countries governed by a religious legal system, such as Saudi Arabia, where marriages contracted abroad might not be recognized if they were contracted contrary to Saudi interpretations of Islamic religious law.
The definition of marriage varies around the world not only between cultures and between religions, but also throughout the history of any given culture and religion, evolving to both expand and constrict in who and what is encompassed, but typically it is principally an institution in which interpersonal relationships, usually sexual, are acknowledged or sanctioned.Civil marriage recognizes and creates the rights and obligations intrinsic to matrimony before the state.When a marriage is performed with religious content under the auspices of a religious institution it is a religious marriage.This forced Gough to disregard sexual access as a key element of marriage and to define it in terms of legitimacy of offspring alone: marriage is "a relationship established between a woman and one or more other persons, which provides a child born to the woman under circumstances not prohibited by the rules of relationship, is accorded full birth-status rights common to normal members of his society or social stratum." Economic anthropologist Duran Bell has criticized the legitimacy-based definition on the basis that some societies do not require marriage for legitimacy.He argued that a legitimacy-based definition of marriage is circular in societies where illegitimacy has no other legal or social implications for a child other than the mother being unmarried.
