“De Maria numquam satis” – about Mary we can never say enough.
“Allow me to praise you, O Most Holy Virgin. Give me strength against your enemies.” – St. Maximilian M. Kolbe

About the book

With careful and thorough documentation and reasoning, Jonathan Fleischmann aptly shows that it is indeed true that “we can never say enough” of the Blessed Virgin Mary and that, in staying close to her, we are also protected from error and heresy. Jonathan Fleischmann uses both a priori and a posteriori arguments, in accord with the thought of Blessed John Duns Scotus, to show that it is no mere poetic expression but a sober truth that we can never praise highly enough the Blessed Virgin Mary. In the course of the book, he provides a rich selection from the writings of canonized saints from every period of the life of the Church to illustrate their witness to the truth that one cannot praise highly enough the Immaculate Virgin.

It is my hope and prayer that, through the study of Marian Maximalism, the Blessed Virgin Mary will draw you ever closer to her Heart, totally one with the Heart of Jesus, and, therefore, ever closer to the Heart of her Divine Son, Jesus Christ. May Marian Maximalism inspire its readers to an ever greater Marian devotion, and through devoted love of Mary, to an ever deeper knowledge of her Divine Son, to worship of Him alone “in spirit and in truth” (Jn 4:23–4), and to serving Him with an undivided heart.

Dr. Fleischmann’s study of the old axiom: De Maria numquam satis, is a wonderful testimony not only to the fact of Marian maximalism, but to the need of it in striving to be “perfect as our heavenly Father is perfect” (Mt 5:48). Saints from every place and age have made this extraordinarily clear. And all of them have clearly distinguished be- tween a maximalism which is phony and one which is genuine, one which brings together the love of the Father of the Word Incarnate with that of His Mother in the mystery of the Incarnation.
