Fr. Sebastian Walshe is the author of Understanding Marriage and Family, in which he defends the traditional Catholic view of marriage, using natural law
and the philosophy of St. Thomas Aquinas. Walshe developed this book by teaching moral theology to high school boys, answering their most pressing
questions. He shows that marriage is natural, not man-made, and explains how the traditional teaching on marriage is connected to the essential mysteries
of the Christian faith, including the Incarnation and the Trinity.
Walshe is a Norbertine Canon of the Abbey of St. Michael in the Diocese of Orange, California, and a regular guest on Catholic Answers Live.
