The setting for tonight's Mass will be Kevin Allen's Missa Cunctipotens Genitor Deus.
From The Liturgical Year:
Peaceful conqueror of souls! Pontiff beloved of God and man! we venerate thee as the perfect imitator of the sweetness and gentleness of Jesus. Having learnt of him to be meek and humble of heart, thou didst, according to His promise, possess the land. Nothing could resist thee. Heretics, however obstinate; sinners, however hardened; tepid souls, however sluggish; all yielded to the powerful charm of thy word and example...
Pray for us to Our Lord, that our charity may be ardent like thine; that the desire of perfection may be ever active within us; that we may gain that introduction to a devout Life which thou hast so admirably taught; that we may have that love of our neighbour, without which we cannot hope to love God; that we may be zealous for the salvation of souls; that we may be patient and forgive injuries, in order that we may love one another, not only in word and in tongue, but as thy great model says, in deed and in truth.
