D&C 82
The covenant that is required of Edward Partridge, Newel K. Whitney (both bishops), A. Sidney Gilbert, Sidney Rigdon, Joseph Smith, John Whitmer, Oliver Cowdery, W. W. Phelps, and Martin Harris is a covenant of consecration. With such an unbreakable covenant they would trust each other to work in all diligence to advance the work they had mutually covenanted to do. This is the kind of covenant that secrete combinations are patterned after. The difference is that such a combination of light cannot be stopped even when it is known publicly where the combinations of darkness lose all effect when brought to public knowledge unless the public is accepting them.
