How wonderful! We sang Veni Sancte Spiritus, albeit heavily simplified, singing only that line over and over, at the Pentecost Mass today, during the communion. It was sung with reverence and gusto! I must be getting really old, sentimental as I already am by nature, because I wanted to cry when that was being sung. It didn't matter that we didn't sing the entirety of the song in Latin, Latin rite though we are. Liturgy will always develop, but it's important that we never forget our Latin roots. More importantly, we must worship with all our heart!
Come, o Holy Spirit, fill the hearts of Your faithful, and kindle in them the fire of your love! Send forth Your Spirit, and You shall renew the face of the earth! Veni Sancte Spiritus!
