So if you have declared that the apparition is valid (as they have done), then there can be no "problem" with its visionary. There cannot be a problem with one and not the other. If you insist on holding this position, it is sophistry.
The false argument is not on my part, neither am I deceiving myself or intending to deceive others.
The Church has yet to declare the Medjugorje apparitions are valid.
The Commission, according to Pope Francis, has its doubts about the claims of ongoing apparitions.
Of course there can be a “problem” with one visionary or more, even if the first set (7?) of apparitions are approved. You are basing your argument on the premise that all the visionaries are truthful in their claims. One may not be; even five. But that would not deny the truth that Our Lady appeared in apparition to one or more.
Ask yourself why only three of the seven Kiebho visionaries were approved – and why Henry Hoser was sent to Medjugorje for pastoral reasons, a priest who also served on the medical commission evaluating the Kibeho apparitions.
Consider this statement given by Mons Hoser at his press conference in Medjugorje on April 5, 2017.
I would like to mention the apparitions in Kibeho. I lived in Rwanda for 21 years and I participated in the work of Commission of doctors for the apparitions that happened a year after Medjugorje. The Blessed Virgin Mary had already showed the spectrum of the genocide that took place 12 years afterwards. That was one warning. The message is similar to the message here in Medjugorje, it is invitation to conversion, to peace, and those apparitions were recognised by the Church. Those places are like sister towns, I would say, according to the historical context and nearness of the period when they took place. There were many doubts whether the visionaries were genuine or not, whether they were saying fairy tales or not, and so on. Some of them were, actually, rejected. Therefore, I would like to invite you to have patience, because as the issue is more complex, it takes more time to come to valid conclusions.
Let me repeat Mons Hoser: “It takes more time to come to VALID conclusions.”
Notice also that his concluding statement came after the words: “There were many doubts whether the visionaries were genuine or not, whether they were saying fairy tales or not, and so on. Some of them were, actually, rejected.”
