But what if it is not due to a simple retention of old customs now turned stale by the changing times? What if the denial of the LDS priesthood to Negroes is a matter of revealed doctrine? In that case, the situation is no longer simple. The prestige, reputation, and vitality of the LDS church itself would be perhaps irretrievably involved on the wrong end of a moral issue. (In order to maintain a claim to divine inspiration, a religion should not, or rather cannot, have its revelations found to be in error.) Unfortunately, any change in a revealed practice carries with it the inescapable suspicion that the practice was wrong to begin with, and therefore, was possibly not too inspired . . .

McKay, who is president of the Mormon Church, has made the following statement: "I know of no scriptural basis for denying the priesthood to Negroes other than one verse in the Book of Abraham (1:26)."
