Catholic Answers speaker and apologist Matt Fradd answers a caller who asks how to respond to a friend who says pornography use is no big deal.

Matt Fradd is Australian by birth and Catholic by choice. After experiencing a profound conversion at World Youth Day in Rome in 2000, Matt committed himself to inviting others to know Jesus Christ and the Church He founded. As a missionary in Canada and Ireland, Matt proclaimed the Gospel to over ten thousand teens and young adults. Matt has also served the Church through full-time lay ministry in Australia, Ireland, Canada, and Texas.

Matt has been seen or heard on the BBC, EWTN, The Irish Morning Show, and Catholic Answers Live, where he has shared his personal story of sin, redemption, and healing to people all over the world.

Recently, Matt, his fearless Texan wife, and their three beautiful children (Liam, Avila, and baby on the way) moved to sunny San Diego where Matt now works as an Apologist and Speaker with Catholic Answers. Matt best demonstrates his infectious passion for the faith when he speaks about the many wounds that pornography inflicts, the healing that Christ offers in the Sacraments, and the freedom that the Church proposes in Her teachings on the virtue of chastity.
