Excellent article on Orthodox practice. But perhaps it should be pointed out that marriage is also considered to be one of the Seven Sacraments in the Roman Catholic Church. But it differs from most of the other sacraments because the Priest officiates or presides, but does not actually administer the Sacrament. The bride and groom do that, as they speak the words, “With this ring I thee wed, in the name of the Father, and of the Son, and of the Holy Ghost.”

Who did also bless Your servant Abraham, and opened the womb of Sara, and made him the father of many nations; Who bestowed Isaac upon Rebecca, and blessed her offspring; Who joined Jacob and Rachel, and from them made manifest the twelve patriarchs; Who yoked Joseph and Asenath together, and as the fruit of generation did bestow upon them Ephrem and Manasse; Who accepted Zacharias and Elizabeth, and declared their offspring the Forerunner;
Who out of the root of Jesse, according to the flesh, produced the Ever‑Virgin Mary, and from her were Incarnate-born for the salvation of the human race; Who through Your unspeakable Grace and plentiful goodness were present in Cana of Galilee, and blessed the marriage there, that You might show a lawful union, and a generation there from, is according to Your Will; do You Yourself, O Most Holy Master, accept the prayer of us, Your servants; and as You were present there, be present also here with Your invisible protection.
Bless (+) this marriage and grant unto these Your servants (Name) and (Name) a peaceful life, length of days, chastity, love for one another in a bond of peace, offspring long‑lived, fair fame by reason of their children, and a crown of glory that does not fade away.
Account them worthy to see their children's children. Keep their wedlock safe against every hostile scheme; give them of the dew from the Heavens above, and of the fatness of the earth. Fill their houses with bountiful food, and with every good thing, that they may have to give to them that are in need, bestowing also on them that are here assembled with us all their supplications that are unto salvation.
For a God of mercy and of compassion, and of manbefriending love are You, and to You do we send up Glory: as to Your eternal Father and Your All‑Holy, Good, and Life‑creating Spirit, both now and ever, and to the ages of ages.
