Gordon B. Hinckley said this quote
“ I have now been an officer in this Church for a very long time. I am an old man who cannot deny the calendar. I have lived long enough and served in enough different capacities to have removed from my mind, if such were necessary, any doubt of the divinity of this, the work of God. We respect those of other churches. We desire their friendship and hope to render meaningful service with them. We know they all do good, but we unabashedly state—and this frequently brings criticism upon us—that this is the true and living Church of our Father in Heaven and His Son, the Lord Jesus Christ. ”
