Religious aspects of weddings

In virtually all religions, marriage is a life-long union between two or more people and is established with ceremonies and rituals. The people are most commonly one man and one woman[citation needed], though some religions have permitted polygamous marriages and some faiths and denominations recognize same-sex marriages.
In marriage, Christians see a picture of the relationship between Jesus Christ and His Church. In Judaism, marriage is so important that remaining unmarried is deemed unnatural. Islam also recommends marriage highly; among other things, it helps in the pursuit of spiritual perfection. The Bahá'í Faith sees marriage as a foundation of the structure of society, and considers it both a physical and spiritual bond that endures into the afterlife.[29] Hinduism sees marriage as a sacred duty that entails both religious and social obligations. By contrast, Buddhism does not encourage or discourage marriage, although it does teach how one might live a happily married life and emphasizes that married vows are not to be taken lightly (see separate article for details).
Different religions have different beliefs as regards the breakup of marriage (see divorce). For example, the Roman Catholic Church believes that marriage is a sacrament and a valid marriage between two baptized persons cannot be broken up by any other means than death. This means that civil divorcés cannot remarry in a Catholic church marriage as long as their spouse is alive.
In the area of nullity, religions and the state often apply different rules, meaning that a couple, for example, could have their marriage annulled by the Catholic Church but still be married in the eyes of the law because the state disagrees with the church over whether an annulment can be granted in a given case. This produces the phenomenon of Catholics getting church annulments simultaneously with civil divorces, so that they may remarry both legally and sacramentally. The Catholic Church will not, in fact, grant an annulment petition unless the marriage has also been dissolved or annulled under civil law. Though sometimes styled "Catholic divorce", an annulment means not a dissolution of a marriage, but the recognition that a marriage has not taken place at all. This applies to sacramental marriages; marriages between an unbaptized and a baptized person can be dissolved according to Canon law.
