CWB II says the source of the text of this sung prayer for the married couple is unknown, and I certainly can’t find the source either.
They set it to HYMN TO JOY following the excellent practice of familiar tunes for less common liturgies. Flipping yesterday’s recommendation from CWB II, I think this may be better with HYFRYDOL.
1 May God’s light of joyous blessing shine upon these two, we pray;
Brighten now this glad occasion as we gather here today.
Let them hear the voice of music, know the scent of fragrant flow’r,
Feel the touch of solemn beauty in the the quiet of this hour.
2 When they hold their hands with promise of kind trust and loving care,
Strengthen, guide, sustain, unite them in the life they now will share.
May God’s gift of joyous blessing rest upon these two, we pray.
Always follow them and keep them, favour them along the way.
With assembling for Mass cancelled in many places the traffic on this site has declined remarkably. Which is lovely, because it means that in normal times the site really is used to assist people putting together the music for liturgies.
