Since 1530, being given permission by Pope Clement VII, the Franciscans have been permitted to celebrate this feast with a proper Office. The Proper Offices of Franciscan Saints and Blessed in the Liturgy of the Hours (English translation prepared by the Friars of Franciscan Liturgical Projects 1977) contains a fully proper office for this memorial, but for the sake of brevity I shall reproduce here only the Antiphons and Prayer, if you wish to use them in private devotion.
Invitatory Ant. Come, let us worship the glorious Name of Jesus; it is above every other name.
CANTICLE OF ZECHARIAH Ant. He Gave himself up to free his people and to acquire for himself a name forever.
Prayer
O God,
you appointed your only-begotten Son redeemer of the human race
and commanded that his name be called Jesus.
May we who venerate his name on earth
also enjoy his presence in heaven,
who lives and reigns with you and the Holy Spirit,
one God, forever and ever.
CANTICLE OF MARY Ant. He who is mighty has done great things and holy is his name.
