Mark P. Shea (born August 5, 1958) is an American author, blogger, and speaker working in the field of Roman Catholic apologetics.
Born on August 5, 1958, and raised in Everett, Washington, Shea describes himself as a "double-jump convert[,] raised more or less as an agnostic pagan, [who] became a non-denominational Evangelical in 1979, and entered the Catholic Church in 1987".
Shea's one-minute "Words of Encouragement" segments have been broadcast nationally in the United States on Ave Maria Radio.
Shea also appeared on EWTN in the made-for-television film adaptation of Chesterton's play The Surprise,[16] as the captain of the guard.
In 2015, Shea appeared in Convinced, a documentary by Donald J. Johnson on the conversions of over 20 people to the Catholic faith.
