_Conscience not always a safe Guide._--I have admitted that conscience is not infallible. Is it, then, a safe guide? Are we, in all cases to follow its decisions? Since liable to err, it cannot be, in itself, I reply, in all cases, a safe guide. We cannot conclude, with certainty, that a given course is right, simply because conscience approves it. This does not, of necessity, follow. The decision that a given act is right, or not, is simply a matter of judgment; and the judgment may, or may not, be correct. That depends on circumstances, on education partly, on the light we have, be it more or less. Conscientious men are not always in the right. We may do wrong conscientiously. Saul of Tarsus was a conscientious persecutor, and verily thought he was doing God service. No doubt, many of the most intolerant and relentless bigots have been equally conscientious, and equally mistaken. Such men are all the more dangerous, because doing what they believe to be right. _It is, nevertheless, to be followed._--What, then, are we to do? Shall we follow a guide thus liable to err? Yes, I reply, follow conscience; but see that it be a right and well-informed conscience, forming its judgments, not from impulse, passion, prejudice, the bias of habit, or of unreflecting custom, but from the clearest light of reason, and especially of the divine word. We are responsible for the judgments we form in morals, as much as for any class of our judgments; responsible, in other words, for the sort of conscience we have. Saul's mistake lay, not in acting according to his conscientious convictions of duty, but in not having a more enlightened conscience. He should have formed a more careful judgment; have inquired more diligently after the right way. To say, however, that a man ought not to do what conscience approves, is to say that he ought not to do what he sincerely believes to be right. This would be a very strange rule in morals.
