Well, my main concern was just that I didn't want anyone to get the impression that Christ's redemption discriminates.

So far as the broader issue of exorcists exorcising non-Catholics, Bishop McKenna was a rather world-renowned exorcist and a great many of his exorcisms were of non-Catholics, including this one:

I think that when you are an exorcist, you have a rather narrow focus when you encounter someone who is possessed: get the devil out.  
.

Ok, I could agree with that in general and in particular with Bishop McKenna, but not Malachi. If you read the other snippets from those interviews, the man was probably a candidate for being "perfectly possessed" himself. He certainly didn't hold that being a member of the Catholic Church is necessary for salvation.

I think Martin was at best an opportunist looking to cash in on the sensationalism pregnant in Catholic traditionalism.  At worst he continued as a proper operative of the enemy, very deliberately controlling the opposition (at best he only 'inadvertently' controlled it).  
.
What do you think about the end of his life?  I always found it curious that he associated with Coomarswamy and 'threw in' with obscure Thuc consecrations.  It makes me wonder if, toward the end of his life, he truly converted.  Simply because those activities are not lucrative in the slightest, and he didn't appear to have made any attempt to leverage the associations of his dying years.  It's easy to see how his books, his association with Art Bell, etc. were creative cash grabs.  I don't see that in his final years' activity.

I think one has to be a little more than "creative" or "greedy" in order to put forth the kind of satanic sham he was accustomed to on a regular basis. Take his close friendship with yahoo psychiatrist Scott Peck for example: Malachi repeatedly encouraged this layman to conduct his own exorcisms on his patients. Malachi never repented of this.

At this archaeological stage of his life-in-review, we are continually digging up massive evils hidden just below the surface or even lazily scattered in plain sight. There is no commensurate repentance, no signs of deep sorrow or regret for dedicating his life to the Lie and therefore no reason to expect he converted at all. For an ordinary Catholic to act like this, would there even be a question? For a priest, you're looking at a distinct kinship with Judas.  Also note how he shares his tomb with that of his rumored mistress.

He showered the conservative Catholic crowd with silver-tongued validations so effectively that it's hard for most people even to comprehend how someone so evil could say things so pleasing to our TLM sensibilities. Our enemy seems to know us better than we do ourselves! And what an enemy! There is no entity who mixes truth with fiction more effectively than the antichrist spirit himself. If we truly believe that the "spirit of VII" is this same spirit, and Malachi had a crucial role in helping it to succeed and later to propagate itself while at the same time pretending to be a staunch opponent of it, there is only one natural conclusion.

Don't waste any prayers on that man.

No prayer is wasted but merely reallocated.

It depends on how deluded we happen to be. If we make Malachi's salvation a major driver for our spiritual life, our prayers are not wasted so much as they are thinly disguised conditions placed on God which in turn only serve as occasions to lose our own faith. I hope these replies aren't passive aggressive attempts to try to get a parting shot in. Don't say you're grasping for straws when you're really looking for arrows! The Art Bell interviews took place within the last three years of his life; he died in July 1999 and the last of his 7(!) Art Bell appearances took place almost exactly a year before that in July 1998.

You could pray for Savile or Epstein too, but I don't think Heaven would mind it if you aimed for more worthy subjects either among the living or the Holy Souls in Purgatory. It certainly wouldn't be a matter to insist that others agree with you. If you think either one of those men were greater deceivers than Malachi was in proportion to their comparative state in life, that's a discussion I'm not interested in having. Though I will add that the deplorable circuмstances in which certain men exit this life should not be lightly waved off to hope for purgatory. There is a good reason why most people don't come out with a deathbed conversion fit for an episode of Law & Order after a whole lifetime dedicated towards evil. The only thing that set Malachi apart was his ability to masquerade as an angel of light.

If Malachi did somehow manage to make it into Purgatory, I don't see why part of his penance couldn't be having all the prayers intended for him redirected to those he deceived and to those who nearly went to Hell because of his best efforts. But what am I saying? I'm sure you include those souls already!

Right?
