Mark Shea, popular Catholic author and speaker, will present a series of talks Oct. 19 and 20 in Corbett Hall at St. Brigid Church.

Shea will give a series of talks at St. Brigid beginning on Friday evening and continuing on Saturday morning. The talks will include: “By What Authority,” an explanation of Catholic sacred tradition—part examination of faith and part mystery story; “Making Sense of the Scriptures,”a “fly-over” of the Biblical story from Genesis to Revelation; and “This Is My Body,” the real presence in the Eucharist.

Shea, a nationally and internationally known author and speaker, is a “double-jump” convert to Catholicism. After being raised more or less as an agnostic pagan, he became a non-denominational evangelical in 1979 and entered the Catholic Church in 1987.

Shea’s Christian and non-Christian background has enabled him to be an effective writer on the issues of the Catholic faith. He is the author of several books and is an award-winning columnist, having contributed many articles to “This Rock,” as well as other Catholic magazines. He is also the senior content editor for CatholicExchange.com and co-authors “Catholic Scripture Study,” an online Catholic Bible study, with Scott Hahn and Jeff Cavins.

Shea’s unique sense of humor makes him a popular speaker both on TV and radio. He is a frequent guest on many radio talk shows and hosts the one-minute “Words of Encouragement” for Catholic Exchange. In his spare time, Shea spends time with his wife of 24 years and their four sons.

Doors open at 7 p.m. on Friday, Oct. 19, and at 9:30 a.m. on Saturday, Oct. 20. Registration forms and information are available on the St. Brigid Web site at www.saintbrigid.org. Pre-registration is requested and can be sent to RE@saintbrigid.org. There is no cost for the seminar, but a free-will offering will be taken up to help support quality programs at the parish.
