Music for the 15th Sunday in Ordinary Time

I'm on my musical vacation at least through the end of this month, so the pastor's been "calling the tunes" for Mass. Here's what we had yesterday:

Entrance: "Baptized in Water"

(no Offertory or Communion music)

Postcommunion: Two short pieces here. First, the chorus of "O Sacrament Most Holy," repeated three times to the tune NON DIGNUS:

O Sacrament most holy,
O Sacrament divine,
All praise and all thanksgiving
Be every moment Thine.

This was followed by a Byzantine Communion chant (being biritual, our pastor has some affinity with Eastern Rites and holds them up as a model for congregational singing), again, repeated three times:

Receive the Body of Christ,
Taste the goodness of immortality,
Alleluia, alleluia.

Recessional: "Holy God, We Praise Thy Name"
