I recently finished a great book that I heartily recommend to my Evangelical and apologetic Catholic readers.
Born Fundamentalist, Born Again Catholic by David B. Currie
I’ve started reading another good one.
On Being Catholic by Thomas Howard
Whereas the first speaks more directly and personally to fundamentalists/Evangelicals, the second is more "intellectual" in nature. I find Howard’s sophisticated style of argument more appealing and accessible than Currie’s casual style and I’m anxious to find more time to continue reading. Those Evangelicals interested in exploring Catholicism and Catholics interested in attracting Evangelical friends or family members to the Church would be served well by both books.
