During the Mass and Office we also have the chance to hear the wonderful collect composed by St. Thomas Aquinas, which is also, of course, chanted at Benediction of the Blessed Sacrament:

passionis tuae memoriam reliquisti,
ita nos Corporis et Sanguinis tui sacra mysteria venerari,
ut redemptionis tuae fructum in nobis iugiter sentiamus.
