Few men are better qualified to write a book in this field than Dr. Wyckoff, who was one of the artificers of the Presbyterian Christian Faith and Life series, and has also worked within that denomination in the development of materials for Indians and Spanish-speaking peoples. The National Council of Churches has enlisted him not only in its youth program, but in its interdenominational effort to achieve some coordination and sense of mutuality in the efforts the major Christian denominations have made to achieve types of curriculum material more suited to the conditions under which the educational process must this day be undertaken. Dr. Wyckoff does live in a rarefied atmosphere, however, for only a few people are really engaged in planning a Christian Education curriculum. The average person would not know what to do with all this information if he did manage to read it. For the specialists in Christian education this is a very comprehensive book. To any one else it may prove tedious reading. Indeed, Dr. Wyckoff's fondness for long outlines and unanswered questions might leave the average Sunday School superintendent or well intentioned Minister of Education merely confused.
