“It is to be earnestly recommended that Elders abroad on missions, as indeed Latter-day Saints in general, avoid contentious argument and debate regarding doctrinal subjects. The truth of the Gospel does not depend for its demonstration on heated discussions; the message of truth is most effectively delivered when expressed in words of simplicity and sympathy.

“The history of our missionary work already written proves the futility of public debate and argument between our Elders and their opponents; and this in spite of the fact that in the great majority of such undertakings the forensic victory has been won by our representatives. A testimony of the truth is more than a mere assent of the mind, it is conviction of the heart, a knowledge that fills the whole soul of the recipient.”

— Joseph F. Smith, “Counsel to Missionaries,” 1903
