The Mystery of the Church: Models and Images is the outcome of the love of the Church that Naiju Kalambukattu cherishes. This volume took shape in his fertile thought backed by the ingenious scholarship that is characteristic of him, and the dogged tenacity that is part of the way in which he works when he gets down to a literary project. The entries are well thought-out and the presentations are so topical and relevant to the Church in the modern times that the work could be considered a source book for modern ecclesiology. The vast number of readers who have enjoyed the previous volumes from Naiju Kalambukattu will find this volume a little more serious in its subject matter but no less enjoyable.
