"Stephen Langton, the 13th-century Archbishop of Canterbury, famouslysaid, 'If you wish to learn, five things are necessary: purity of life, simplicityof heart, an attentive mind, a humble disposition, and a gentle spirit.' AbbotVonier's book on the Eucharist exemplifies the beauty and radiance of all fiveof these virtues. Not since St. Thomas Aquinas's treatment of this sacramentin the Tertia Pars of his Summa Theologiae has there been a more lucid andserene presentation of the Catholic understanding of the Eucharist than thisbook. It should be required reading in every course in sacramental theologyin every Catholic seminary and college in the nation."- Edward T. Oakes, S.J.
"A Key to the Doctrine of the Eucharist is one of the few classics inCatholic theology composed in English... This book, remarkable for its balance,depth, and accessibility, should never be out of print."- Avery Cardinal Dulles
