Paulist Press has come out with two books by Dominican friars of the [Eastern USA] Province of St. Joseph:
101 Questions & Answers on The Da Vinci Code and the Catholic Tradition, by Nancy de Flon and Fr. John Vidmar, OP. "De Flon and Vidmar not only show where Brown went wrong, but they also unlock the doors (that Brown ignored) to the treasure rooms of the Catholic tradition and they display for the reader the wealth of people, customs, and events that comprise Catholic identity. Far more than a mere Da Vinci Code 'debunker,' 101 Question and Answers on The Da Vinci Code and the Catholic Tradition serves as celebration of Catholic culture that uses The Da Vinci Code as its springboard."
101 Questions & Answers on the Eucharist, by Fr. Giles Dimock, OP. "He starts off with questions on the Jewish background of Eucharist and then examines the Last Supper and its theology in the light of the Paschal Mystery. Some of the other questions deal with transubstantiation, sacrifice, Real Presence, communion, and intercommunion. Fr. Dimock's answers are both practical and ecumenical."
