The Rosary at Mass

"Fr. Joseph Jungmann's Christian Prayer Through the Centuries [gave] particulars especially from modern centuries about the encroachment of private devotions on the faithful's attendance of the Mass. Yet, all those devotions, such as the recitation of the Rosary during the Mass, were genuine devotions, often vibrant with the best spiritual intentions. They all served the purpose of prompting a full commitment to doing God's will, which actually is the very thing enacted in a supreme measure when the priest renders Christ present on the altar. While those customs can rankle the liturgical purist, he cannot say that they were not full of the sense of the supernatural. — Stanley L. Jaki, What is the Mass?, 2009, p. 4.
