Traditional prayer for a married couple
O Merciful God, we beseech Thee ever to remind us that the married state is holy, and that we must keep it so; Grant us Thy grace, that we may continue in faithfulness and love; Increase in us the spirit of mutual understanding and trust, that no quarrel or strife may come between us; Grant us Thy blessings, that we may stand before our fellows and in Thy sight as an ideal family; And finally, by Thy mercy, account us worthy of everlasting life: For Thou art our sanctification, and to Thee we ascribe glory, to the Father and to the Son and to the Holy Spirit, now and ever and unto ages of ages. Amen.
Prayer by Archimandrite Nicodim (Mandita)
O Lord Jesus Christ our God, our Sweet Savior, Who taught us to pray always for each other, so that by thus fulfilling the holy law we will be made worthy of Thy mercy: look down with compassion on our married life and keep from all perilous falls, from enemies both visible and invisible, my husband/wife whom Thou hast granted me, that we may pass our time together until the end with oneness of mind. Grant him/her health, strength, and fullness of wisdom enlightened from above, so that he/she may be able to fulfill his/her duties all the days of this life according to Thy will and commandments. Protect and keep him/her from temptations, and may he/she be able to bear and conquer those temptations that come upon him/her. Strengthen him/her in right faith, strong hope, and perfect love, so that together we may do good deeds and that we may order all our life according to Thy divine ordinances and commandments.
O Greatly-Merciful Lord, hear us who humbly pray to Thee, and send Thy divine blessing in truth on our married life and on all our good deeds, for it is Thine to hear and have mercy on us, O our God, and to Thee we ascribe glory: to the Father and to the Son and to the Holy Spirit, both now and ever, and unto ages of ages.
