A week after Joseph Ratzinger became Pope Benedict XVI, liturgical scholar Dom Alcuin Reid predicts what he will do about the liturgy. A monk of the Monastere Saint-Benoit in Frejus-Toulon, France, his book The Organic Development of the Liturgy carried a preface by then-cardinal Ratzinger.His 2007 article Summorum Pontificum a restoration after a gross impoverishment appeared here last week. This article, titled "A feast for the famished," appeared in the 29 April 2005 issue.   Our Holy Father, as is well known, is a distinguished theologian. What may not be widely appreciated, however, is the centrality of the Sacred Liturgy to his life and work. Nor may it be understood why the Sacred Liturgy shall, in all likelihood, be an area of particular concern to him. The young Joseph Ratzinger grew up in a Germany enjoying the first fruits of the twentieth century Liturgical Movement — an attempt to rediscover the spiritual value of the rich liturgical tradition of the Church. And that, the young man did. His memoir, Milestones, records the gift of a bi-lingual missal that enabled him to discover this treasure. As for so many, the Liturgical Movement introduced him to the prayer book of the Church, the missal, and taught him the theological importance of the Sacred Liturgy: the manner in which the Church prays determines what she believes.
