In brief, trust not in any who exalt you, but in those who humiliate you. For this is the judgment of God: “He hath cast down the mighty from their seat, and hath exalted the humble.” See how unlike Christ was to His successors, though all will have it that they are His vicars. I fear that in truth very many of them have been in too serious a sense His vicars, for a vicar represents a prince who is absent. Now if a pontiff rules while Christ is absent and does not dwell in his heart, what else is he but a vicar of Christ? And then what is that Church but a multitude without Christ? What indeed is such a vicar but antichrist and an idol? How much more rightly did the Apostles speak, who call themselves servants of a present Christ, not the vicars of an absent one!
