10 “O worship the Lord in His holy court”: in the Catholic Church; this is His holy court. Let no man say, “Lo, here is Christ, or there. For there shall arise false prophets.” Say this unto them, “There shall not be left here one stone upon another, that shall not be thrown down.” You are calling me to the whited wall; I adore my God in His holy court. “Let the whole earth be moved before His face.”
