Jesus tells the parable of the rich man and Lazarus:
“There was a rich man who was dressed in purple and fine linen and who feasted sumptuously every day. And at his gate lay a poor man named Lazarus, covered with sores, who longed to satisfy his hunger with what fell from the rich man’s table; even the dogs would come and lick his sores. The poor man died and was carried away by the angels to be with Abraham. The rich man also died and was buried. In Hades, where he was being tormented, he looked up and saw Abraham far away with Lazarus by his side. He called out, ‘Father Abraham, have mercy on me, and send Lazarus to dip the tip of his finger in water and cool my tongue; for I am in agony in these flames.’ But Abraham said, ‘Child, remember that during your lifetime you received your good things, and Lazarus in like manner evil things; but now he is comforted here, and you are in agony. Besides all this, between you and us a great chasm has been fixed, so that those who might want to pass from here to you cannot do so, and no one can cross from there to us.’ He said, ‘Then, father, I beg you to send him to my father’s house—for I have five brothers—that he may warn them, so that they will not also come into this place of torment.’ Abraham replied, ‘They have Moses and the prophets; they should listen to them.’ He said, ‘No, father Abraham; but if someone goes to them from the dead, they will repent.’ He said to him, ‘If they do not listen to Moses and the prophets, neither will they be convinced even if someone rises from the dead.’”
It is ordinarily understood that Abraham is blaming the men for refusing to believe Moses and the prophets, and indeed, for refusing no matter how strong the reasons given for believing them.
While one should refrain from judging people subjectively, it seems reasonable to think that such an absolute refusal is morally blameworthy. In this sense, Hume’s refusal to accept the fact of a miracle on any testimony whatsoever is morally blameworthy. But this is not limited to people’s rejection of religious beliefs or testimony in favor of them. In a similar way, without remarking on his subjective situation, Kurt Wise’s refusal to accept the fact of evolution, no matter how much it is supported by evidence, may be morally blameworthy.
But Abraham’s statement in the parable may be true in a more general way, one which is not relevant to praise or blame. It can be understood as a general statement about the relationship between testimony and external support such as miracles. If someone is a credible witness, a miracle may support his testimony. But if someone is not a credible witness, he will not suddenly become credible because a miracle happens.
In May 1990, Bishop Pavao Zanic published a statement, “The Truth about Medjugorje” (text here, pp. 45-63). This text contains the following:
16. The “seer” Ivan Dragicevic. Regarding the “great sign”, Vicka mentions this 13 times in the diaries, it is mentioned 14 times in the Parish chronicle, 52 times on the cassettes, and on numerous occasions in talks with the bishop. In the spring of 1982, I asked the “seers” to write everything they knew about the sign without making the “secret” public. The way I suggested they do it was to write down information on paper in duplicate. Then this would be sealed in an envelope and one copy would remain with them, and one with the bishop. Then, when the “sign” occurs, we would open the envelopes and see whether or not the “sign” was predicted. Father Tomislav Vlasic, pastor of Medjugorje at the time, told the “seers” to say that Our Lady had told them not to write anything down for anybody, and so they did not. Ivan Dragicevic was in the Franciscan minor seminary at Visoko, Bosnia at that time and he wasn’t informed of this on time. Two members of the first commission, Dr. M. Zovkic and Dr. Z. Puljic (now bishop of Dubrovnik), went to visit Ivan in Visoko. They gave him a sheet of paper which was somewhat greenish in colour with questions typed out on it. Ivan wrote down the content of the “sign”, dated the document and signed it in their presence without a word or any sign of fear. A few years later, Father Laurentin wrote that Ivan told him personally that he wrote absolutely nothing down on that sheet of paper and that he tricked the two members of the commission. On 7 March 1985, three members of the commission went to ask Ivan if what Laurentin writes is true. Ivan said it was true, and that they could freely go ahead and open the envelope in the chancery office because in it they will only find a white sheet of paper. They came back to Mostar where the commission was having a meeting and before all the members, they opened the envelope. In the envelope on a greenish sheet of paper they found written the content of the sign:
Our Lady said that she would leave a sign. The content of this sign I reveal to your trust. The sign is that there will be a great shrine in Medjugorje in honour of my apparitions, a shrine to my image. When will this occur? The sign will occur in June. Dated: 9 May 1982. Seer: Ivan Dragicevic.
“There will be a great shrine” is intended to mean that one will be miraculously created, without being built by human beings. And although in principle it is possible to take “the sign will occur in June” ambiguously, namely that it will occur in June of an unknown year, it is plain enough that Ivan was writing about June 1982.
Needless to say, this did not happen. And the consequence is that Ivan Dragicevic is not a trustworthy witness to the truth. He is not trustworthy because of the false claim that there would be such a sign, and he is not trustworthy because of the false claim that he wrote nothing on the paper.
And the fact that he is not trustworthy will not be changed simply by external support. His testimony is not credible. And it remains that way even if rosaries turn to gold, and would remain that way even if someone were to rise from the dead.
