36 Honor, then, to those who shrink not from entering the arena as often as need calls, believing and being convinced that the violence of injustice will be brought to an end and finally give way to the sanctity of right and religion! They truly seem invested with the dignity of time honored virtue, since they are struggling to defend religion, and chiefly against the faction banded together to attack Christianity with extreme daring and without tiring, and to pursue with incessant hostility the sovereign Pontiff, fallen into their power. But men of this high character maintain without wavering the love of obedience, nor are they wont to undertake anything upon their own authority. Now, since a like resolve to obey, combined with constancy and sturdy courage, is needful, so that whatever trials the pressure of events may bring about, they may be "deficient in nothing,"(33)We greatly desire to fix deep in the minds of each one that which Paul calls the "wisdom of the spirit,(34) for in controlling human actions this wisdom follows the excellent rule of moderation, with the happy result that no one either timidly despairs through lack of courage or presumes overmuch from want to prudence. There is, however, a difference between the political prudence that relates to the general good and that which concerns the goodof individuals. This latter is shown forth in the case of private persons whoobey the prompting of right reason in the direction of their own conduct; whilethe former is the characteristic of those who are set over others, and chieflyof rulers of the State, whose duty it is to exercise the power of command, sothat the political prudence of private individuals would seem to consist whollyin carrying out faithfully the orders issued by lawful authority.(35)
