The Christian Trinitarian formula has been expressed in many other ways throughout history, including in secular disciplines. Here are some possible correlations.
The "Holy Ghost" is perhaps one of the most mysterious figures in Mormon theology (and perhaps more generally in Christianity). Many Mormons likely know this being of the Godhead as a "personage of spirit," which "has not a body of flesh and bones," "were it not so, the Holy Ghost could not dwell within us" (D&C 130:22). This already begins to sound quite supernatural, a ghostly person that may come and dwell within me? How are we to make sense of this?
How should we regard the Godhead, or the Trinity as many Christians call it, taking into consideration biological evolution, particularly human evolution, and other modern science?
