First Presidency: Many Do Not Recognize Either Him (Satan) or His Methods

“Satan is making war against all the wisdom that has come to men through their ages of experience. He is seeking to overturn and destroy the very foundations upon which society, government, and religion rest. He aims to have men adopt theories and practices which he induced their forefathers, over the ages, to adopt and try, only to be discarded by them when found unsound, impractical, and ruinous. He plans to destroy liberty and freedom–economic, political, and religious, and to set up in place thereof the greatest, most widespread, and most complete tyranny that has ever oppressed man. He is working under such perfect disguise that many do not recognize either him or his methods... Without their knowing it, the people are being urged down paths that lead only to destruction. Satan never before had so firm a grip on this generation as he has now.”
