All the organizations named are strictly within the place of the Priesthood: but in addition there are auxiliary organizations, such as Relief Societies, Sabbath Schools, Young Men's and Young Ladies' Mutual Improvement Associations, Primary Associations, and Religion Classes. The Relief Societies, which form a vast net-work over all the stakes, wards, and most of the missions, are women's organizations, for the care and comfort of the sick and the needy. The Deseret Sunday School Union has a membership of over 150,000. The Mutual Improvement Associations are what their name implies: the sexes meet separately, except in monthly conjoint sessions, and study systematically religion, history, philosophy, and the arts and sciences. The Primaries are for the training of children too young for membership in the Mutuals; and the Religion Classes are for special instruction to the youth of both sexes. Church schools exist in many of the stakes, the most notable being the Brigham Young University of Provo, the Brigham Young College of Logan, and the Latter-day Saints University of Salt Lake City. Old folks' committees, for the entertainment of the aged, regardless of sect or creed, are another institution of the Church, and are found in most of the stakes and wards throughout Zion.

The Gospel Dispensations CHAPTER I. Introductory One Plan of Salvation.--As there is but one Savior, so is there but one plan of salvation. There never was, and there never can be, another "I marvel," wrote Paul to the back-sliding Galatians, "that ye are so soon removed from him that called you into the grace of Christ, unto another gospel; which is not another; but there be some that trouble you, and would pervert the gospel of Christ. But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed."--(Galatians 1:6-8.)
