In Hac Tanta §14

¹⁴ We can hardly recount "the gratitude of this apostle for these signs of affection nor express the comfort which the pope's esteem brought him. Inspired by the power of divine mercy'' the saintly man received the strength and the heart to undertake the greatest and most difficult things: to build new churches, hospitals, monasteries, and strongholds; to travel to new countries preaching the gospel; to establish new dioceses and to reform old ones, removing the vices, the schisms, and the errors; to sow everywhere true dogma and virtues, the seeds of Christian faith and life; and even to civilize barbaric peoples made savage by inhumanity. This he achieved by using pious disciples and many persons summoned from England.
