Exploring the beauty and challenge of Catholic marriage, this week’s episode of "Catholic Review Radio" features author and homeschooling mother Caitrin Bennett discussing her award-winning book, "Holier Matrimony: Married Saints, Catholic Vows and Sacramental Grace." A parishioner of St. John Francis Regis Parish in Leonardtown, Bennett shares how her desire to find married saints as companions in her own vocation grew into a richly layered work on saintly couples, Catholic wedding vows and sacramental grace.
