Famous quotes containing the word direct:
“Long as I have lived, and many blasphemers as I have heard and seen, I have never yet heard or witnessed any direct and conscious blasphemy or irreverence; but of indirect and habitual, enough. Where is the man who is guilty of direct and personal insolence to Him that made him?”
