Yeah the Fatima movement of Gruner, Ferrara and the SSPX (which supports it). Needs Malachi Martin to continue their story, he also happens to tickle the ears of conspiracy nutters. There is such a thing as fact and conspiracy, sometimes certain people can't make that distinction. There are things that used to be conspiracy that are now fact... There are also conspiracies that have some weighty arguments, but that means that they are probably true they cannot however be presented as truth itself. The same goes with those who hold the Siri thesis, he is an essential element to many theories. Malachi Martin could have even been right of what he said, the problem is when the only testimony you have is a pathological liar who was working for Jewish interest and admitted this several times in public. He understood very well how to manipulate people and told them precisely what they wanted to hear which is why he is so popular. This is why he appeared to be pro-indult, pro-sspx, pro-Novus Ordo, pro-Sedevacante...
This is why so many staunchly defend a pathological liar that he is, and this comes from someone who has read his books... Once you do the research on a lot of claims that he makes, you come to realize the man was a fraud and therefore any good that he does is attributable to the truth that he did say. It is also important that he never recanted any of his evil deeds which were public before, so that the whole argument "he changed" does not hold water. Anyone that has done the amount of damage that he has done needs to let those he has deceived as to what the damage he did was. Never once will you ever hear a peep from his mouth, making retractions as to the secret covert stuff he was doing during the Second Vatican Council. He also should have continued living as a priest and dressing as a priest, instead of wanting to be addressed as Malachi. This is a first sign that something is fishy and something is wrong. Everything about this man from every single aspect gives you the red alert of a classical fraudster.
Read Characters of the Inquisition, by Walsh. He goes over the sect of the Alumbrados, which was a Luciferean sect that had invaded the convents/monasteries all over Spain. These guys would be the precursors to the modern gnostic Masons. Well there was one particular nun, that had done great prodigy miracles Jew's, Muslims and others had converted to the Catholic faith as a result. The Church was completely packed on the inside and the outside, yet she was a servant of Satan. It cannot be said that because there are conversions that had happened through Malachi Martin that it means he was a good guy, I hear this very often with the false modern apparitions of Our Lady. Most of all Medjugorje, too many people say "see the fruits, see the fruits" and I tell them I don't care if they converted a million people they preach heresy. Simple as that, no more questions asked after that point.
Never take anything he says seriously, simply stay away from him.
