[I]t is important to state that dialogs are contrary to the doctrines of the Catholic faith. Dialogs presuppose the coming together of two equal and opposing sides; therefore, in no way could (dialog) have anything to do with the Catholic faith. We believe and accept our faith as the only true faith in the world. All this confusion ends up in compromises, which destroy the church's doctrines, for the misfortune of mankind and the church alike.  ~Archbishop Marcel Lefebvre, suppressed interview of 1978.
