In this revised edition of her groundbreaking original volume, Zeni Fox emphasizes the crucial relationship between lay ecclesial ministers and the Church's response to them in light of the many developments in recent years. Written in a clear, crisp style, the book is divided into three parts: Part one describes the present reality, both sociological research about who these new lay professionals are and a review of the ways in which theologians are reflecting upon this new phenomenon. The second part explores the new reality from the standpoint of tradition, including Scripture, the documents of Vatican II and the work of U.S. bishops. The final part assesses this reality in light of the tradition, and outlines steps needed to more fully integrate lay leaders into the fabric of the Church.
