Translated from the Spanish by Roberto Hope

          I traveled around the planet 
          preaching to the entire World
          the doctrine of man-made "god",
          not the teachings of our Lord.

          Not that of our Holy Mother
          Church, the bride of the Son of God;
          nor that of the Holy Fathers
          nor the Tradition, of course.

          Did not preach the Holy Gospel,
          the Ten Commandments much less,
          nor even the Seven Sacraments
          'cause in these, I believe less.

          Oh, what a spectacle, gentlemen!
          't was swallowed by half the World.
          Not in vain I've been an actor
          and a comedian so thorough
          in the Great Stage of the World,
          of the greatest of the fakers,
          of deceivers' the overlord.
