Simply the best book on explaining the Catholic Faith I have read. Absolutely everyone, whatever their beliefs may be, should read it.
As an active Youth Minister for the Catholic Church I find Fr. Lukefahr's writing style easy to read and understand. I have used "The Priviledge of Being Catholic" extensively for preparing for R.C.I.A. classes and others that I teach. Also Oscar's book is easy to lend out to parents who have youth who ask tough questions that the parent's do not feel comfortable answering.
Oscar's use of the Sacramental Principle to explain alot of the Catholic teachings that Non-Catholics often attack, helps the non- theologian to practice good Apologetics. A workbook is also available that helps a teacher to use Ocsar's teachings in a classroom setting. I highly recommend "The Priviledge of Being Catholic" to any professional lay or religious minister in the Catholic Church and those who question the biblical basis of Catholic teaching and practices.
