MARRIAGE in the Orthodox Church is forever. It is not reduced to an exchange of vows or the establishment of a legal contract between the bride and groom. On the contrary, it is God joining a man and a woman into "one flesh" in a sense similar to the Church being joined to Christ (Ephesians 5:31, 32). The success of marriage cannot depend on mutual human promises, but on the promises and blessing of God. In the Orthodox marriage ceremony, the bride and groom offer their lives to Christ and to each other—literally as crowned martyrs.
According to a statement by the Standing Conference of the Canonical Orthodox Bishops in the Americas (SCOBA) in 2003, "The Orthodox Christian teaching on marriage and sexuality, firmly grounded in Holy Scripture, 2000 years of church tradition, and canon law, holds that marriage consists in the conjugal union of a man and a woman, and that authentic marriage is blessed by God as a sacrament of the Church. Neither Scripture nor Holy Tradition blesses or sanctions such a union between persons of the same sex. . . . The Orthodox Church cannot and will not bless same-sex unions. . . . This being said, however, we must stress that persons with a homosexual orientation are to be cared for with the same mercy and love that is bestowed by our Lord Jesus Christ upon all of humanity. All persons are called by God to grow spiritually and morally toward holiness."
