Msgr. Joseph DeGrocco, pastor of Our Lady of Perpetual Help, Lindenhurst, has written a new book, “The Church at Worship: Theology, Spirituality and Practice of Parish Liturgy,” published by Liturgy Training Publications.

The book is a collection of columns written by Msgr. DeGrocco for The Long Island Catholic Newspaper discussing the principles and fundamentals of Catholic worship. It’s a pastoral approach to celebrating the liturgy and to understanding how participation in the rites is internal and external at the same time, and how such participation changes us to be at service to the world in building the Kingdom of God.
