[David O. McKay]
Henry D. Moyle'called him and discussed the matter of missionaries now in the home, 137 of whom the draft boards have refused to clear. Among these are thirteen who have been set apart and stated that it is my opinion they are in a different status than the others who have not been set apart' that they now have the authority of the Priesthood. ... I then said that probably in order to lay the proper foundation for an appeal we should let the thirteen boys get own attorneys and ask them to accompany them to their draft boards, and present their minister's certificate and ask to be classified in 4-D in order that they might fulfill their missions. Brother Moyle said he thought the Church should not be known in it; that it would be better to come through the individuals and their own attorneys. Said if the missionaries do not have attorneys that he could probably suggest some of them.
