The Palm Sunday Communion Song: Pater, si non potest ("Father, if this cup cannot pass away")

The Communion hymn for Palm Sunday, Pater, si non potest, is the last chant of the day, sung during Communion after the Passion gospel has been sung:





The text, taken directly from Matthew 26:42, is a short and sad ending for the Palm Sunday liturgy:

Pater, si non potest hic calix transire, nisi bibam illum: fiat voluntas tua.
Father, if this cup cannot pass away, unless I drink it: your will be done.
