Romans 5:5b (alt.)
Caritas Dei diffusa est in cordibus nostris, alleluia:
per inhabitantem Spiritum eius in nobis, alleluia.
(God’s love has been poured into our hearts, alleluia:
Through the Holy Spirit indwelling in us, alleluia.)
Benedic anima mea Domino et omnia a quae intra me sunt, nomini sancto eius.
(Bless the Lord, O my soul, and all that is within me, bless his Holy name.)
Here’s my SSA (with divisi) setting of the traditional Caritas Dei text, suitable for Pentecost.
And the usual PDF sheet music of Caritas_Dei, of course. You can also download this piece from CPDL. It’s under a CC by-SA license.
