Marriage (also, matrimony) is one of the seven holy mysteries or sacraments in the Orthodox Church, as well as many other Christian traditions. It serves to unite a woman and a man in eternal union before God, with the purpose of following Christ and His Gospel and raising up a faithful, holy family through their holy union. It is referred to extensively in both the Old and New Testaments. Christ declared the essential indissolvibility of marriage in the Gospel.
A wedding is the holy ceremony which joins the spouses-to-be.
