8 And now, when more than a few European nations have been lost to the Church because of the changes in these calamitous times, We see your people and their Spanish brothers opening paths and laboring for the Church in the spacious lands of Africa, Asia, and America. There they recruit numerous adherents of the Church to replace those who have miserably left her embrace. Then dioceses, parishes, sacred seminaries, monasteries, hospitals, and public orphanages arise almost everywhere in these places to prove the vital force and perennial virtue of the Catholic Church.
