From the Sacrament of Holy Matrimony
O God, our God, Who was present in Cana of Galilee and blessed the marriage there, do You also bless these Your servants, who, by Your providence, are joined in the community of marriage. Bless their comings-in and their goings-out. Replenish their life with all good things. Accept their crowns in Your Kingdom unsoiled and undefiled, and preserve them without offense to the ages of ages.
Another Prayer from the Sacrament of Holy Matrimony
O Lord our God, who in Your saving dispensation declared marriage honorable by Your presence in Cana of Galilee, keep in peace and concord your servants, whom you have joined together as one. Make their marriage honorable. Preserve their union undefiled; grant that they may live together blamelessly; and make them worthy to attain to a ripe old age, fulfilling Your commandments with a pure heart.
For You are our God, the God of mercy and salvation, and to You we send up glory, together with Your Father Who is without beginning, and Your all-holy, good, and life-creating Spirit, always, now and forever, and to the ages of ages. Amen.
