The object of this book is to provide the clergy and laity with a practical guide to the building and remodelling of Catholic churches, and to give a summary of the laws governing their planning and furnishing. Before an architect can design a church he must understand the functional nature of the different parts of the building. It matters very little in the long run whether he has "good taste"! For as the late Eric Gill loved to remind us: "unless a workman knows what he is making he cannot make anything. Whether it be a church or only a toothpick, he must know what it is; he must have it in his mind before he begins, before he can even choose his material or lay his hand on a tool." The trouble with so many churches erected during the past century is that architects have been far more concerned with the superficial "beauty" than with the nature of the building. Their object, so it seems, was to create a building that looked what most people believed a church ought to look like rather than a building that fulfiled the practical functions of a place of worship. They often managed to erect a building that superficially reproduced the plan and details found in houses of God in past ages, but which were an anachronism in modern times. Such architects did not know what they were making. Very often they took no trouble to learn. They wanted to create a "work of art" and ignored the fact that nothing can be a work of art if it does not properly fulfil its end. Peter Anson has asked me to Americanize his book, and to add such notes as will make it provocative for the reading public in this country. He insistently told me not to pull any punches, and to be my own self as he knows me from articles and letters. Peter and I are old friends from the days when he drifted into our rectory at Bremerhaven to our last meeting in Ascot and my visit to his temporary home near Gravesend, where he had time to indulge his passion -looking at ships. His marine background and love for the sea should not deceive us. As a former Anglican and then Catholic monk of Caldey, and as a Tertiary of St. Francis and addict of quiet little monasteries in small Umbrian towns and on Tuscan hillsides, his architectural training and ecclesiastical background are more than sufficient to equip him to write this book, and to write it well enough to make it not only interesting, but also safe and instructive reading for priests, architects, seminarians, and sacristans. It competes with any ordinary book on matters rubrical and liturgical by its use of common sense and historical knowledge, instead of piling up mountains of authors, authorities, and mere legal decisions. The outstanding feature is the fact that Peter Anson represents the liturgical wing of art, architecture, and rubrics. He is thoroughly and refreshingly British, but not to a degree which might make him appear as foreign on our shores. He is imbued with what is good in tradition, and modem with an ingredient of AngloSaxon humor. I had little to add, and less to change, and when I did so, the initials H. A. R. warn the reader of it. In a few places, as Anson's excursion on rood-screens, I registered mild disagreement. In a few places I felt called upon to reinforce the color of the author's statement, which seemed too pale to me, in view of the fact that he had touched on a subject more burning here than in Britain. This is a practical book. It will help any man who feels that he agrees with the tenets of the liturgical movement, but cannot find a down-to-earth application of its lofty principles. Especially the parish priest and the architect who cannot go to the expensive places that "make the right things well" will welcome this book as a good friend for those who have to make small means do.
