Many inquiries are made as to the precise signification of these letters that follow the names of many Scientists. They indicate, respectively, the degrees of Bachelor and Doctor of Christian Science, conferred by the Faculty of the Massachusetts Metaphysical College. The first is given to graduates from the Primary Class; the second is conferred on those who, after receiving the degree of "C. S. B.," continue as practitioners of Christian Science during three years, in good and regular standing, and also attend, in the intervening time, some other class or classes of the College. The taking of any or all the other courses, after the Primary, does not entitle a student to the degree of "C. S. D." until the three years of probation and practice shall have passed.
None hath part in God, who cannot demonstrate in part the Divine Principle of the teachings and practice of our Master. If living in disobedience to Him, we ought to feel no security, although God is good and man repentant.—Science and Health.
