"Grant, almighty God, that we may celebrate with heartfelt devotion these days of joy, which we keep in honor of the risen Lord, and that what we relive in remembrance we may always hold to in what we do.  Through. . . ."

"Fac nos, omnipotens Deus, hos laetitae dies, quos in honorem Domini resurgentis exsequimur, affectu sedulo celebrare, ut quod recordatione percurrimus semper in opere teneamus.  Per. . . ."

Cause us, Almighty God, these days of joy, which in honor of the rising-again Lord we follow, with sedulous affection to celebrate, that, what with recordation we run through, always in deed we may keep.  Through. . . .

Freeland & Conway, FC 93 (1996), p. 346).  According to Edmond (Eugène) Moeller, writing in Corpus praefationum, Apparatus A-P (1980), pp. 347-348, and following a 1974 article by P. S. Agrelo (while citing much else), both Sermo 78 and the Preface from which this fragment derives should be dated to the year 441 (2 May 441 according to Freeland & Conway).
