Many Catholic musicians have either not heard of Musicam Sacram or have not taken the time to read the document. It is such a resource for Catholic musicians, and yet many have not utilized these instructions written by the Second Vatican Ecumenical Council. Before you schedule a rehearsal, take a few moments to read through this document! A music ministry will not grow if it does not have a solid foundation.
