"At this time, it is important to remind Catholics around the world that obedience to the pope is not a primary virtue. The hierarchy of virtues begins with the three theological virtues of Faith, Hope and Charity, followed by the four cardinal virtues of Justice, Temperance, Prudence and Fortitude. Obedience is a derivative of the cardinal virtue of Justice. Therefore, it is far from being ranked first in the hierarchy of virtues. Some bishops do not want to give the slightest impression of disobeying the Holy Father. I understand how they feel. It is clearly very unpleasant, if not very painful."
