"Who am I Lord? Or, rather, what is my calling? that you appeared to me in so great a divine quality, so that today among the barbarians I might constantly exalt and magnify your name in whatever place I should be, and not only in good fortune, but even in affliction?"
"So that whatever befalls me, be it good or bad, I should accept it equally, and give thanks always to God who revealed to me that I might trust in him, implicitly and forever, and who will encourage me so that, ignorant, and in the last days, I may dare to undertake so devout and so wonderful a work; so that I might imitate one of those whom, once, long ago, the Lord already pre-ordained to be heralds of his Gospel to witness to all peoples to the ends of the earth. So are we seeing, and so it is fulfilled; behold, we are witnesses because the Gospel has been preached as far as the places beyond which no man lives."
