Charles Tournemire
Acceptabis sacrificium

The text for the Communion proper for the Tenth Sunday after Trinity is a paraphrase of verses from Psalm 51.

Acceptabis sacrificium iustitiae,
Thou shalt accept the sacrifice of justice,
oblationes et holocausta,
oblations and whole burnt offerings,
super altare tuum, Domine.
placed upon your altar, O Lord.

Here is the traditional Gregorian chant of this Communion proper:

Composer and organist Charles Tournemire (1870–1939) is best known for his improvisations on Gregorian melodies. Between 1927 and 1931, he compiled a collection published as L’Orgue mystique, a group of 51 sets of five pieces each. The pieces in each set correspond to one of the days (mostly Sundays) in the Church calendar, and based the Gregorian chant

Here is his setting of the Communion proper for the Tenth Sunday after Trinity, in which the chant melody presented in the embedded recording above comes through clearly. The organist is Eric Koevoets.

Ad te levavi animam meam, Deus meus, in te confido:
non erubescam neque irrideant me inimici mei.
Etenim universi qui te expectant non confundentur.

Unto thee, O Lord, will I lift up my soul; my God, I have put my trust in thee:
O let me not be confounded, neither let mine enemies triumph over me.
For all they that hope in thee shall not be ashamed.

Below is a performance of a setting of this text by Palestrina, sung by The Sixteen, conducted by Harry Christophers.
