Book excerpt: Presiding over the liturgy takes more than following instructions. Good presiding is artful presiding. It is knowledgeable and inspirational. It faithfully grasps the church’s heritage and gives it personal expression. In Ars Celebrandi, Father Paul Turner offers a guide for priests in preparing for and celebrating the Mass. Building on a liturgy which adheres to the liturgical books, Turner examines styles of presiding and reflects on principles that will help the presider to foster active participation of the faithful.
