Most Holy Trinity, Father, Son, and Holy Spirit, You instituted marriage in the earthly Paradise and in the New Law You elevated it to the dignity of a sacrament, attaching to it many graces. Grant to my husband and me the grace to live holily in so sacred a state and, by the practice of Christian virtues, to act always as is becoming a Christian couple. As Your minister joined our hands at the holy altar, so may we journey through life with one heart and soul, tasting its pleasures with moderation, enduring its sorrows with resignation and, at all times, mutually assisting and consoling each other.
May Your true and holy fear strengthen us to serve You uprightly with pure heart and eyes and lips, in mutual esteem and for bearance! Grant that the children born of our union may be pure of heart and well-disposed in mind, and that they may gladly walk in the way of Your Commandments. Teach us to be faithful images of the Holy Family of Nazareth, of the blessed foster-father Joseph, of the most devout Mother Mary, the most blessed Mother of the Child Jesus, that we may be made worthy to live under their protection, to die in their favor, to be forever blessed in their company.
