[J. Reuben Clark]
Richard G. Grant, son of Walter A. Grant who works in the PBO, called about a subject that is worrying him a great deal: woman's position in the home, in life, towards authority and toward polygamy; he cannot understand the inequality toward woman; that she cannot hold the Priesthood; whereas man can have more than one wife sealed to him, a woman can only have one husband. ...
Bro. Grant said he had worried about it until it is affecting his sanity, that he had talked it over with his bishop and others and they had not been able to satisfy them, and he just did not think it was just. Pres. Clark asked him if that was the only injustice in the world.
To the specific question of "why", Pres. Clark said: "I do not know. I do not think anybody else knows. The Lord did not set it up that way. Why he did not, you can theorize about it, but you won't get anywhere on it ... I do not worry about things that I can't understand or explain and I do not worry about things I can't change."
Bro. Grant said, "I guess that is the answer."
In the evening, Pres. Clark said that Bro. Grant had called on Luacine, that he was a friend of hers, that his problem seemed to be that he wanted to get married but the girl won't marry him, because she is afraid he will have another wife in the Hereafter besides her.
