But the most remarkable account came from Richard Jackson, an architect who served in the Church Building Department from 1968 through the time of McKay's death in 1970: I remember one day that President McKay came into the office. We could see that he was very much distressed. He said, ‘I’ve had it! I’m not going to do it again!’ Somebody said, ‘What?’ He said, ‘Well, I’m badgered constantly about giving the priesthood to the Negro. I’ve inquired of the Lord repeatedly. The last time I did it was late last night. I was told, with no discussion, not to bring the subject up with the Lord again; that the time will come, but it will not be my time, and to leave the subject alone. We were all, of course, a little bit dumbstruck. I don’t think that it has ever been written that that happened. . . . I’ve never told anybody about that. I can still see him coming in with a bit of a distraught appearance, which was unusual for President McKay. He always appeared as if he had everything under control."
