The goal of Vox Sacra is to be a model of musical excellence for the Archdiocese and beyond, as well as to share with others the depth and the beauty of the treasury of sacred music found in the Catholic Church, especially its particular treasury of Gregorian chant and polyphony. While most Catholic parishes have choirs in their own communities, very few have the musical resources or the ability to sing more involved, complicated, or difficult music. Vox Sacra has that ability, and does its best to showcase more challenging literature both so it is not lost and so that it can serve its proper role in beautifying the liturgy and edifying the people. Vox Sacra is able to approach music that has a greater musical demand or thick texture in a way that goes beyond making music and embraces the spirituality of the sacred repertoire.
Vox Sacra has several components to its ministry. The members, first of all, form the core of the Indianapolis Archdiocesan Choir, a volunteer choir comprised of singers from all over the Archdiocese. They serve as leaders of this group and a backbone of musicality and support. Vox Sacra also provides music within the Archdiocese for several liturgical events, including Masses, devotions, and other functions both with and separately from the full Archdiocesan Choir. Vox Sacra will sing outside of a liturgical context in concert, though it will still focus almost exclusively on sacred music. It will also travel both within the country and internationally to bring the talents of Indianapolis and the treasury of Catholic sacred music to the country and to the world at large.
