Metanoia: A Catholic Book Series, Book Number Three: Vocation: Common Priest by Baptism (Sixth Edition) is the author’s third publication in a series of Catholic books. In Vocation: Common Priest by Baptism, the author sets forth his personal experience in discerning whether Jesus Christ is calling him to share or participate in The Eternal Priesthood of Christ as a common priest by Baptism or as a ministerial priest by Holy Orders. He is publishing this book in hopes that other Catholic men, who are formally in discernment, may find it instructive. Finally, this book is part of the author’s lay apostolate of Roman Catholic witness to the reality, power, and transforming/saving love of God, as well as the author’s response to and promotion of the Church’s “universal call to holiness” (Lumen Gentium) and the “new evangelization” (Novo Millenio Ineunte), in the electronically and globally connected virtual world of the Internet.
