The Durandus Institute for Sacred Liturgy & Music

The Durandus Institute for Sacred Liturgy & Music aims to evangelize through beauty: by organizing solemn liturgical celebrations through the year, as well providing workshops and consultations for parishes and other local groups in the Philadelphia metropolitan and surrounding regions. The institute takes its name from Giullaume Durand (c.1230-1296), also known as Durandus: a medieval French bishop and liturgical author. His important liturgical work was the 'Rationale divinorum officiorum', a treatise on the symbolism and spiritual significance of church architecture and ceremonies of the Mass and Divine Office. The 'Rationale' was among the first books reproduced by Gutenberg or his associates after the invention of the printing press.
