Focolare, Community of Sant'Egidio, Neocatechumenal Way, Legionaries of Christ, Communion and Liberation, Opus Dei. These are but a few of the most recognizable names in the broader context of the so-called ecclesial movements. Their history goes back to the period following the First Vatican Council, crosses Vatican II, and develops throughout the twentieth century. It is a history that prepares the movements' rise in the last three decades, from John Paul II to Francis. These movements are a complex phenomenon that shapes the Church now more than before, and they play a key role for the future of Catholicism as a global community, in transition from a Europe-centered tradition to a world Church.

From 1991 to 2012, Nathan D. Mitchell was the author of the "Amen Corner" that appeared at the end of each issue of Worship. Readers of Worship grew accustomed to Nathan's columns as invitations to rethink the practice of Christian worship through a liturgical theology that was interdisciplinary, aesthetic, and attentive to history. With the soul of a poet, Nathan was always on the lookout for the turn of phrase, the image, stanza, or metaphor from other classic wordsmiths that could capture the liturgical insight he wanted to explore.
For the first time, this volume assembles some of the most important of these columns around the themes of body, Word, Spirit, beauty, justice, and unity. In addition, Nathan's former students offer substantive commentary through essays that invite the reader to consider how the themes raised by Nathan might develop in the coming years.
This collection is a must-read both for those who admired Nathan's contribution to liturgical studies and for a newer generation of scholars seeking to discern the frontiers of liturgical theology.
