[David O. McKay]
Dr. Edward R. McKay called regarding contraceptives and the Church's stand toward their use. I told him that the Church cannot countenance contreceptives--marriage is for the purpose of having children and rearing a family. If a couple make modifications of this, the responsibility is theirs--they do not have the Church's sanction in the use of contraceptives, and the delaying of having children.
