"The Social Principles of Jesus" takes seventh place in a series of text-books known as College Voluntary Study Courses. The general outline for this curriculum has been prepared by the Committee on Voluntary Study of the Council of North American Student Movements, representing the Student Young Men's and Young Women's Christian Associations and the Student Volunteer Movement, and the Sub-Committee on College Courses of the Sunday School Council of Evangelical Denominations, representing twenty-nine communions. Therefore the text-books are planned for the use of student classes in the Sunday School, as well as for the supplementary groups on the campus. The present text-book has been written under the direction of these Committees.
