"If, therefore, the Greeks or others say that they are not committed to Peter and to his successors, they necessarily say that they are not of the sheep of Christ, since the Lord says that there is only one fold and one shepherd (Jn.10:16). Whoever, therefore, resists this authority, resists the command of God Himself."

It is conceivable that God might have ordained to preach the Gospel directly to man through dreams, visions and revelations. But as a matter of fact, He has not done this; but rather has committed the preaching to man, telling them to go and disciple all nations. The responsibility lies squarely on our shoulders.
