Good enough to repeat...

...the Church has not found it possible to follow along the lines of the present general tendency in the matter of property rights, taxes, the curtailment of rights and liberties of the people, nor in general the economic policies of what is termed the "New Deal"....unless the people of America forsake the sins and the errors, political and otherwise, of which they are now guilty and return to the practice of the great fundamental principles of Christianity, and of Constitutional government, there will be no exaltation for them spiritually, and politically we shall lose our liberty and free institutions....We believe that our real threat comes from within and not from without, and it comes from the underlying spirit common to Naziism, Fascism, and Communism, namely the spirit which would array class against class, which would set up a socialistic state of some sort, which would rob the people of the liberties which we possess under the Constitution, and would set up such a reign of terror as exists now in many parts of Europe....We confess to you that it has not been possible for us to unify our own people even upon the necessity of such a turning about, and therefore we cannot unfortunately, and we say it regretfully, make any practical suggestion to you as to how the nation can be turned about. (Heber J. Grant, also J. Reuben Clark, Jr. and David O. McKay signed as the First Presidency, written during World War II Letter to the U.S. Treasury, September 30, 1941.)
