On a Mission to Preserve Our Worship of the DivineSacred Music and Liturgy After Vatican II recounts the important role that Monsignor Schuler played in the post-Vatican II Church. It was his heroic commitment, through countless writings in Sacred Music magazine, and through the authentic implementation of the Council's Constitution on the Sacred Liturgy at the Church of Saint Agnes in Saint Paul, Minnesota, that has helped keep the patrimony of Catholic sacred music and liturgy alive against all odds in the United States.With the dawning of the 17th century came a "flowering of religion...a spreading of Catholicism in Europe and in the newly discovered western hemisphere. The cause of all this was the Council of Trent and those who put it into effect. When it was finally put into practice, a great age dawned. So also will it come about in these times when the Second Vatican Council is finally given a chance and is put into practice." -Monsignor Richard J. Schuler
