'McPartlan's book is written in a straightforward, uncomplicated style. This is an important achievement given the nature of the subject and the obfuscation one sometimes encounters in an area of this kind. Sacrament of Salvation is a book written by a teacher (helpful diagrams included), with plenty of footnotes to serve as tutorial in the sources quoted or referenced. The text is especially useful for seminarians and other newcomers to the theological scene, such as those in programs of ministerial formation. The eight chapters of even length keep the book moving and provide a solid, practical text for group reading and discussion. This book makes a fine contribution to the ongoing concern for church unity and ecumenical dialogue.' Gabriel B. O'Donnell OP, Antiphon, A Journal for Liturgical Renewal
