Eminently sensible and practical, this book contains a veritable treasure-house of sources and resources. With unaffected simplicity and wisdom, McDermot allows us to hear the voices of many of the great saints and theologians within the Catholic tradition. A most thoughtful and illuminating introduction! -- Fr. Paul Murray OP, Professor of Spiritual Theology at the Angelicum in Rome. Fr. McDermott, O.P. has until now stood out in scholarly circles by presenting Catherine of Siena not only as a saintly mystic but a brilliant theologian as well. Here in his latest work, he draws from his expertise of medieval spirituality (and beyond) to illustrate how true Christian discipleship is not simply a matter of right belief or right action, but to become "filled" with God's very life and thereby become other Christs for the world. McDermott's writing is accurate and alluring, inviting all into this great Catholic transformation. -- Fr. David Meconi, S.J., Assistant Professor of Theological Studies, Saint Louis University Here is a delightfully fresh, clearly expressed vision of Catholicism. It is just what the Church needs today: an invitation to intimacy with God that elicits desire for Him and leaves us in wonder over how blessed we are to be Catholic! This book is perfect for adult faith formation, deacon formation and personal spiritual reading. -- Deacon James Keating, Ph.D, Director of Theological Formation, Institute for Priestly Formation
