It is, therefore, necessary to be suspicious of those who seek to convince us with means other than reason, and of charismatic leaders: we must be cautious about delegating to others our judgement and our will. Since it is difficult to distinguish true prophets from false, it is as well to regard all prophets with suspicion. It is better to renounce revealed truths, even if they exalt us by their splendor of if we find them convenient because we can acquire them gratis. It is better to content oneself with other more modest and less exiting truths, those one acquires painfully, little by little and without shortcuts, with study, discussion, and reasoning, those that can we verified and demonstrated.

In short, I may affirm that one cannot refer to a single quoted prophecy that is not false; or if you would have me speak more mildly, I will only say that they are all ambiguous and doubtful, and are not to be accepted from writers who trifle with things and words.

Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves.

While predicting the future is a rare gift, testifying for the truth is a duty for every woman and man of conscience. …A prophet, Romero added, is one who has an “undisturbed conscience.” This is an interesting statement.
Only those who are firmly rooted in conscience as their moral compass may calmly tell the truth about injustice and corruption, no matter the risks.
And risks there are since prophets easily make enemies.

The striking surprise is that prophets of Israel were tolerated at all by their people. To the patriots, they seemed pernicious; to the pious multitude, blasphemous; to the men in authority, seditious.

Only the prophets see the obvious.

The chief wrong which false prophets do to their following is not financial... But the real harm is on the mental and spiritual plane. There are those who hunger and thirst after higher values which they feel wanting in their humdrum lives. They live in mental confusion or moral anarchy, and seek vaguely for truth and beauty and moral support. When they are deluded and then disillusioned, cynicism and confusion follow. The wrong of these things, as I see it, is not in the money the victims part with half so much as in the mental and spiritual poison they get. But that is precisely the thing the Constitution put beyond the reach of the prosecutor, for the price of freedom of religion or of speech or of the press is that we must put up with, and even pay for, a good deal of rubbish.

Fear prophets, Adso, and those prepared to die for the truth, for as a rule they make many others die with them, often before them, at times instead of them.

Sometimes, in pentecostal gatherings, we treat prophecy too lightly. We don't seem to realize the agony of a prophet. Truly, there is no prophet who hasn't experienced agony.

We are all, at times, unconscious prophets.

Whenever a tradition of the Holy Prophet is related to you, scrutinize it, do not be satisfied with mere verbatim repetition of the same because there are many people who repeat the words containing knowledge but only few ponder over them and try to fully grasp the meaning they convey.

There is no question on whether the prophets existed. We are talking about whether the religions they invented were true. Can you show me the truth of that? Of course, they can’t. None of them can. They don’t want to. They don’t need to. I have seen people make that admission too.

I will raise up prophets to make conflicting pronouncements that inevitably will be garbled in transcription, resulting in mutually exclusive definitions of orthodoxy from which the open-minded will flee in dismay.

… Anyone who doesn't puppet their views is seen as an apostate, a heretic or a traitor, and moderates in the middle are annihilated. Fiction writers are particularly suspect because they write about human beings, and people are morally ambiguous.
