One of the most cherished possessions of every good Episcopalian is the Prayer Book. This monograph dealing with the origin and development of the American Prayer Book and giving an interpretation of its significance will be welcomed by the clergy and laity of that church and by many of other Protestant denominations who regard the Prayer Book as a treasure house of material for private and public devotions. The authors here share the results of their extensive study and research. After a preliminary chapter outlining the church situation in America during colonial and revolutionary times, they give a brief history of the Book of Common Prayer starting with the books prepared in England in 1549 and 1662, and dealing particularly with the American editions of 1789, 1892 and 1928. The closing chapter in ""The Prayer Book Today"" is a beautiful interpretation. The bibliography will be of great value to students of Christian literature and church history...This book has a chance for special publicity in view of the celebration of the 400th anniversary of the English Book of Common Prayer, which is being observed in all parts of the English- speaking world today.
