Let the people praise you, O God; let all the people praise you
What is available
Here is a small collection of Responsorial Psalms and Gospel Acclamations for Weddings and Nuptial Masses, following the suggestions in the Lectionary.
We also have settings for the US and Philippines.
If we don't have the psalm you are looking for, I am very happy to set one – just send me an e-mail!
