The Pope. Before he defines that a given soul is indeed a Saint, the advocates of the cause must prove that the person in question exercised all Christian virtues in a heroic degree—supreme faith, hope, and charity; perfect prudence, justice, fortitude, and temperance. Also God’s own testimony by proven miracles wrought through the person’s intercession is required. The infallibility of the Church in such decisions is, as I have said, but an application of ordinary infallibility in matters of faith and morals, in so far as the Church could not err in proposing a given life as an exemplification of perfect Christian virtue.
