Priest's Prayer for a Married Couple

Lord our God! Caring for the salvation of people, You visited the Cana of Galilee and thereby showed the purity and holiness of marriage. Even today, the children and servants of Yours (names), whom You have allowed to be united with one another, preserve their marriage in true peace, harmony and unity of mind; make their marriage strong and honorable, keep their bed undefiled, help them to lead a life in Your truth and purity, and grant that they may reach a deep old age and with a clean and sincere heart fulfill Your Will and Commandments.

For You are our God, God of Mercy and Salvation, and to You we lift up glory with Your Everlasting Father, and the Holy One, and the Good, and Your Life‑giving Spirit—now, always, and forevermore, Amen.
