The word "Prudence" has been twisted by cowards into the lie that one should never act, but rather think and think and think ad infinitum until either they have talked themselves out of any action (which is always very easy to do) OR until someone else comes along and takes up the slack, thus making the question of their own action moot. In other words, STALLING.Emphasis added by me. I may have more comments when I've read through again, but I'm not sure what else might need saying at this point.
Prudence is being able to discern the right, see the big picture and then DO WHAT NEEDS TO BE DONE. Many people think that they can "legally" dodge this by simply doing nothing. Ah, but they forget that to NOT act is to act, to NOT speak is to speak, to quote Bonhoeffer. It is impossible to avoid action, because inaction is itself an action. When prudence truly dictates that something MUST be said or done, inaction then becomes a sin, no matter how one might try to justify that inaction as prudence. That sin is called COWARDICE.
UPDATE: Nothing I haven't said before --Ms. Barnhardt quotes the same passage in the larger context. You cannot see it too many times.
