larger image

A Key to the Doctrine of the Eucharist is
one of the few classics in Catholic
theology composed in English.

This book, remarkable for its balance,
depth, and accessibility, should
never be out of print.”
Avery Cardinal Dulles, s.j.

Written to give lay Catholics a better understanding of the Eucharist, this book is recognized as a modern spiritual classic. In remarkably clear and straightforward language, it takes the reader step-by-step into the deepest mysteries of the Eucharist — a religiously exhilarating journey into the heart of the Christian faith.

Praise for A Key to the Doctrine of the Eucharist

“This is a beautiful book — one of the great treasures of the Catholic renewal of the last century.”
—Christoph Cardinal Schönborn, Editor, Catechism of the Catholic Church

“Utterly lucid, penetrating, and humble... a jewel of a book.”
—Peter Kreeft, writing in the Preface

“Profound insights… I recommend this excellent book to all Catholics who desire a better understanding of the Mass.”
—Father Kenneth Baker, S.J.
Editor, Homiletic & Pastoral Review

“A classic example of the best twentieth-century Eucharistic theology.”
—Aidan Nichols, O.P., writing in The Holy Eucharist: from the New Testament to John Paul II

“One could wish most earnestly that every Catholic — and every Protestant for that matter — would read Abbot Vonier’s book. Both the mystery and the richness of the Eucharist are here: but the book is splendidly readable — no small achievement.”
—Thomas Howard

“One could spend a lifetime contemplating the many dimensions of the Eucharist, and it would be a life well spent. Father Vonier’s lucid and compelling account will put into his debt Catholics who would spend their lives well.”
—Richard John Neuhaus

“Stephen Langton, the thirteenth-century Archbishop of Canterbury, famously said, ‘If you wish to learn, five things are necessary: purity of life, simplicity of heart, an attentive mind, a humble disposition, and a gentle spirit.’
     Abbot Vonier’s book on the Eucharist exemplifies the beauty and radiance of all five of these virtues.
     Not since St. Thomas Aquinas’s treatment of this sacrament in his Summa Theologiae has there been a more lucid and serene presentation of the Catholic understanding of the Eucharist than this book.
     It should be required reading in every course in sacramental theology in every Catholic seminary and college in the nation.”
—Edward T. Oakes, S.J., Chester & Margaret Paluch Professor of Theology, University of St. Mary of the Lake/Mundelein Seminary

A Key to the Doctrine of the Eucharist is like a breath of fresh air. Thoroughly imbued with the spirit and thought of St. Thomas, I find myself reading each chapter twice, in some cases just to savor the fresh way the author explains the topic, and in other cases to see what I missed.”
–Fr. Jeffrey Keyes, C.PP.S., The New Gasparian weblog; Pastor of St. Edward Parish, Newark, California

“There are so many wonderful things here... I would like to call people to read this book, especially during the Year of the Eucharist.”
—Fr. Mitch Pacwa

“During Lent, I read Abbot Vonier’s book A Key to the Doctrine of the Eucharist. To say it was eye-opening would be like calling Chartres, ‘a pretty little church.’ It was earth shattering. It was truly like finding a lost treasure chest full of the most beautiful jewels in the whole world.
     Vonier takes St. Thomas’s definition of sacrament (one that I had never seen before) and spends the whole remainder of the book applying it to the Eucharist. The book just gets better and better as Vonier delves deeper and deeper into the mystery of the Eucharist.”
–“Jordan Saxony,” Contemplating the Laundry weblog

“About a year ago I purchased A Key to the Doctrine of the Eucharist by Abbot Vonier.
     My reading time is usually late at night when the kids are sound asleep, but I was forced to stay up even later while reading this book for it was very hard to put down.
     In my original copy there are many many dogeared pages for reference.
     Something happened to me that I didn’t think possible; that being a greater understanding and appreciation for our blessed sacrament. My weekly hour of adoration certainly changed with this book. Thank you so much for putting it back into print. I have ended up buying three or four extra copies to give to family and friends, and will be buying more soon since my last extra copy will be given away next week. Needless to say I am very much looking forward to reading more of Abbot Vonier’s works. Please let me know when they are ready to purchase.”

“I bought A Key to the Doctrine of the Eucharist by Abbot Vonier here in Rome. It is a masterpiece. Thank you for making this treasure available.”

“We’re working our way through the sacraments in RCIA presently. I encourage... catechumens and candidates to get their hands on an exceptional book entitled A Key to the Doctrine of the Eucharist by Abbot Vonier.
     The book is a gem, and the first chapters are perhaps the best, and most concise, treatment of the sacraments that I have read. Not merely educational but inspirational.”
—Fr. John Riccardo, Pastor, St. Anastasia Catholic Church, Troy, Michigan

“If you are looking for a book that explains well just what the Church proclaims concerning the Most Blessed Sacrament, then A Key to the Doctrine of the Eucharist is for you.”
—Msgr. Charles M. Mangan

“The ONE book to read, if you are to read only one, on the centrality and consummate power of the Eucharist.”

“I recently purchased A Key to the Doctrine of the Eucharist at the Franciscan University of Steubenville bookstore and all I can say is ‘WOW!’ I can’t wait to see your future releases.”

“I just purchased A Key to the Doctrine of the Eucharist. Thank you for this really astounding book.”

“...An inspired ability to explain the deepest theological truths with relative simplicity. And could this man write! ...This is definitely recommended reading in the Year of the Eucharist.”
—Fr. Mark Withoos, writing for the Melbourne Catholic Lawyers Association

“I heartily second the recommendation for Abbot Vonier’s Key to the Doctrine of the Eucharist. It’s one of the best books on the subject that I’ve ever read (and I’m in the middle of a two year research project on the history of Eucharistic doctrine).”

“I arrived home yesterday to find waiting for me a delightful surprise. I had just received a copy of a new book from a new Catholic publisher, Zaccheus Press.
     Being the inveterate reader I am, I couldn’t wait to plunge into A Key to the Doctrine of the Eucharist. Also being an editor, I couldn’t resist taking in the overall package. And let me say I am extremely pleased.
     I have been blessed by reading just a little of this book. And glancing through the rest, it is exciting, challenging, interesting, and informative. Sparkling clarity of thought... Wonderful, wonderful food for reflection.
     It isn’t terribly difficult to read, but it goes slowly because each chapter is a stunning revelation...”
—Steven Riddle, Flos Carmeli weblog

“Abbot Vonier explains the Catholic doctrine of the Real Presence with clarity and precision by focusing on the sacramental element in the Eucharist. Chapters 20, 21 and 22 are especially compelling, and could stand alone as independent essays.”
–Oswald Sobrino, Catholic Analysis weblog

“Highly recommended. There is much here to nourish you intellectually, and also to nourish your contemplative prayer life in reflecting on the great gift that God has given us in the Eucharist.”
–Jeff Miller, The Curt Jester weblog

“An excellent book. Abbot Vonier’s writing is profound enough to yield a deeper meaning each time it is pondered.”
–Tom Kreitzberg, Disputations weblog

“I think it is not only the best modern book out on the Eucharist, it is also the best Thomistic book I have read (of those written in the last 200 years)! Abbot Vonier gives a very good account of the Eucharist and also explains St. Thomas’ Sacramental theology in general.
     His discussion of the real presence is superb! It is a must read for all modern Thomists.”
