The conformity, docility and passivity of laymen within the Church, unfortunately encouraged and promoted by many members of the hierarchy during a transitional time in history, is now haunting their successors eager to adapt the Church to the cultural and intellectual challenges and theological frontiers of a new day. Don Thorman last year spoke for the silent layman in The Emerging Layman (1962 supplement p. 617). Now Daniel Callahan puts the whole case in clear perspective in The Mind of the Catholic Layman which offers readers a concise history of the Catholic layman in the United States from colonial times to the present. It is frank and honest, putting the record straight, for example, on many of the ""great"" Catholic pioneers whose contribution to the Church was not quite what over-exaggerated Catholic histories have led many to believe. Lay trusteeism and the ""Americanism"" heresy are succinctly described and refreshingly evaluated. Mr. Callahan's thorough study is a positive and insistent appeal for the Church to accept a dynamic conception of Catholic life which stresses freedom and maturity, a creative and positive assent to Church authority, rather than blind and fearful obedience. Most important, Mr. Callahan details how it could be done. This is a provocative book -- a catalyst to dissipate the apathy in the millions of laymen who have not yet seen that it is time to emerge again.
