1 God, to whom the secrets of the heart of man are open, knows that it is because of my love for Christian peace that I am so deeply moved by the profane deeds of those who basely and impiously persevere in dissenting from it. He knows also that this feeling of mine is one tending towards peace, and that my desire is, not that any one should against his will be coerced into the Catholic communion, but that to all who are in error the truth may be openly declared, and being by God's help clearly exhibited through my ministry, may so commend itself as to make them embrace and follow it.
