Another matter. We hope that you who teach in the various organizations, whether on the campuses or in our chapels, will always teach the orthodox truth. We warn you against the dissemination of doctrines which are not according to the scriptures and which are alleged to have been taught by some of the General Authorities of past generations. Such, for instance, is the Adam-God theory. We denounce that theory and hope that everyone will be cautioned against this and other kinds of false doctrine.
