45 May God Who is One in Three, whose nature is goodness, whose will is power, receive these burning desires, through the intercession of the Blessed Virgin Mary, Mother of God, the Holy Apostles Peter and Paul, and Euphemia the Virgin Martyr, who triumphed at Chalcedon. Do you, venerable brethren, add your prayers to ours for this cause, and see that what we have written to you is made known as widely as possible. Giving you now our thanks for this, to you and to all priests and to all Christ's faithful, whose spiritual advancement lies in your care, lovingly we bestow the apostolic blessing. May it enable you to take with greater readiness Christ's yoke upon you, a yoke that is neither heavy nor harsh, and may you become more and more like to him in humility, of whose glory you hope to be sharers.
