5 Such are the words of praise Our Predecessor wrote after Charles' death. Now, three centuries after his canonization, "we can rightly rejoice on this day when We solemnly confer, in the name of the Lord, the sacred honors on Charles, Cardinal Priest, thereby crowning his own Spouse with a diadem of every precious stone." We agree with Our Predecessor that the contemplation of the glory (and even more, the example and teaching of the saints) will humiliate the enemy and throw into confusion all those who "glory in their specious errors." Saint Charles is a model for both clergy and people in these days. He was the unwearied advocate and defender of the true Catholic reformation, opposing those innovators whose purpose was not the restoration, but the effacement and destruction of faith and morals. This celebration of the third centenary of his canonization should prove to be not only a consolation and lesson for every Catholic but also a noble incentive for everyone to cooperate wholeheartedly in that work so dear to Our heart of restoring all things in Christ.
