Yikes! RC Exorcist Padre Gets Heave-Ho From DC Archbishop After Linking UFOs To Demons

 

                                      Fictional exorcisms from Hollywood film fare

                                                 D.C. exorcist Stephen Rossetti

A paranoid Catholic priest ,  Mgsr. Stephen Rossetti, has been removed from his role as an exorcist after making remarks linking UFOs to demons. Has he been talking to J.D. Vance? See e.g.:

Brane Space: JD Vance Claims That Aliens Are "Demons" - Is It Tied To A Pentagon Cabal Of Fundamentalist Extremists?

Rossetti, meanwhile, is reported by Newsweek to be "a well-known exorcist in Washington, D.C."  This in itself is somewhat confounding given the Vatican hierarchy decades ago admitted that the Church's ritual of exorcism was founded and promulgated not on the belief that demonic possession was real, but that the afflicted person believed it was real

Thus, the rite of exorcism was initiated as a memetic template to cure the belief in the person's possession, not any objective possession per se. Up to now, indeed, no one - including the padre, far less any pope- has been able to prove beyond any reasonable doubt that any demonic possession has ever occurred. How could it have if there are no such entities as 'demons'? Indeed, I destroyed the whole concept of 'demons' in a blog post from 5 years ago:

Demons Are Real? Yeah - And Ghosts, Elves And Goblins Too - According To Too Many 'Muricans in YouGov Poll

So it was gratifying to learn Rosetti was relieved of his duties by Cardinal Robert McElroy, the Archbishop of Washington, D.C., after saying in a May 29 video that “many, if not most,” UFO sightings "could be explained as demonic activity."

On what basis, padre?  Did you actually SEE a demon in one, or piloting one? If so when?  Do you have the name of said demons involved in this activity? No, didn't think so.

McElroy took action on June 3 and said the comments “gravely undermined” official Catholic teaching on demons and exorcism, which again, that the first are a fantasy and the latter a therapeutic intervention aimed at curing the person's belief in possession.

This prompted the archdiocese to also cut ties with the center that is headed by Rossetti. Also a good move, given serious RC prelates don't want their church going any further down the rabbit hole of nutso -land.

Rossetti later said he was saddened by the decision and apologized, pledging to remain obedient to Church doctrine. If you are then stop the infantile demonic babbling and do more research into actual UFOs, and their physical basis. E.g.

Brane Space: Yes - Scientific Analysis of UFOs Is Certainly Possible!

Rosetti stepped in it when he talked bunkum about UFOs and aliens in a recent Facebook video,  blabbing this poppycock:

There’s a danger here. As an exorcist I wanted to raise that danger. And that is that demons like to hide…They don’t want us to know what they’re doing because they’re more effective when we don’t realize it. They can kind of get into your head, you know, and manipulate things in the world to influence us to do evil."

Adding:

It’s my personal belief that probably many if not most of these UFO sightings are in fact demons.” 

Stated with absolutely no proof, including that a 'supernatural' even exists. Something I referenced in a June, 2018  Physics Today essay:

Readers’ thoughts on science and religion - Physics Today

In a statement posted on the St. Michael Center website, Rossetti said:

“I ask forgiveness for any ways that I have not been faithful to the teachings of the Church’s Magisterium, particularly in the cited video on ‘aliens and the demonic.’

Then do yourself and your church a favor, padre, and cease with the phantasmagorias of trying to tie obvious alien craft - space craft - to 'demons'.

Even for JD Vance, it was a weird moment. Over the weekend, the vice president appeared on the podcast of Benny Johnson, a sycophantic MAGA media figure tied to the conservative advocacy group Turning Point USA. The two discussed the Trump administration’s aggressive immigration crackdown, Medicaid fraud and the SAVE Act, which would undermine Americans’ freedom to vote, and Vance even accused Rep. Ilhan Omar, D-Minn., of immigration fraud. But in a blatant attempt to snag the attention former president Barack Obama received for discussing aliens during a recent podcast appearance, the conversation turned to the extraterrestrial and UFOs, which the Yale-educated Vance argued are actually demons.

The vice president pretended to pivot from “a longer discussion” of the subject, but then he immediately started pontificating about the culture’s “desire” to classify “celestial beings who fly around” as “aliens.” The Christian interpretation, he argued, should be demons, because “one of the devil’s great tricks is to convince people he never existed.”

JD Vance on UFOs: “I don’t think they’re aliens; I think they’re demons.”

Anaïs Nin: “We don’t see the world as it is, we see it as we are.”

We don’t see the world (or the phenomenon) as it is — we see it as we are. High time the exorcists known as clinical mental health workers were dispatched to Vance’s DC residence.

The Vice President, as do an evangelical cadre of top US Air Force brass, warn, UFOs are piloted by inter-dimensional things that go bump in the night. By the evidence, the primary threat to the security of the US homeland: an acute episode of shared psychosis inflicting men in positions of power.

With Respect For My Revolutionary War Ancestors I Won't Be Celebrating A 250th Under Trump

 

            There is little doubt that my ancestors - Jacob and Conrad Brumbaugh, knowing what the rest of us know of Trump, would regard him as a traitor unworthy of any Independence celebration.

"Cadet Bone Spurs has developed a taste for flaunting our unparalleled military, and there’s no one at the Pentagon to curb this new appetite for global violence — certainly not the aggro Pete Hegseth… When Trump was a celebrity developer, people laughed at his megalomania in plastering his name everywhere. He grabbed buildings by the crotch. But now that he is president, it’s not funny. It’s foul.

Now, in his frenzied quest for ubiquity, he will deface U.S. currency. The Treasury Department announced on Thursday that Trump would become the first sitting president to have his signature on paper money.

He continues his amoral, pseudo-macho posturing — just with a bigger stage and the biggest weapons." - Marueen Dowd, NY Times

Let us acknowledge the past is important to reference for perspective as well as to sustain a grounding in reality for current events. This is why history is so important: not to memorize and regurgitate a bunch of disconnected dates, but to ascertain and grasp how power is won and lost and especially - in our case- how democracies can emerge and then perish. 

Now, nearly one third into his 2nd and undeserved term, we can see what a vile, amoral and demented beast Trump is. Like a mad chimp in a zoo's ape house, Trump has been on an 16-month ego bender hurling his feces at everything in D.C. Tearing down the East Wing of the People's House (not his), fouling every wall, every nook with his gold bling, and now also proclaiming he wants a Nazi-style Arc de Trump, as well as re-doing the WW II Memorial, after already plastering his feral face on the Justice Dept.

In light of the latter, many sentient Americans - those not trapped in the bubble of fake news spewed out by FOX -  know full well our Republic is in dire, manifest peril. This ought not be "rocket science" but it is for a large swath of the public - namely the MAGA cult- daily fed lies by "Trump TV" and its assorted Trump surrogates across the media spectrum.  Surrogates and sycophants who refuse to do their duty and remove this  sociopathic felon under the 25th amendment. A felon who exhibits the most dangerous personality disorder, that of the malignant narcissist.

The Malignant Narcissist in author John Eddy's view (Why We Elect Narcissists and Sociopaths)is the most dangerous type of high conflict personality precisely because the condition is "untreatable".   This is the case for Trump, who is also seriously demented, as he tries to conflate our 250th celebration with himself:

Trump FURIOUS As ‘Freedom 250’ Event COLLAPSES BECAUSE OF HIM!! | The Kyle Kulinski Show

This is in the from of his bogus 'Freedom 250'  event which has merely been exposed as a celebration of himself. But the mega-narcissism has been his undoing as numerous original acts have bailed.  Let's bear in mind this is good given Trump is a malignant narcissist, the worst kind. As John Eddy notes (p. 14):

"The Malignant Narcissist can be particularly powerful, confident and aggressive. They can look charismatic while promoting grandiose plans. They are ruthless, heartless and lack a conscience. They are also paranoid and sadistic, say the experts, and are more driven than most narcissists or sociopaths to destroy their targets of blame."

He then (p. 15) goes on to cite Erich Fromm's diagnosis of Hitler and his warning: "This narcissism is malignant because it is not restrained in its growth like a malignant cancer."

This is exactly like Trump, given each new power display or grab - whether extortion of money from universities and legal firms, national guard occupations of blue cities, etc. is followed by more displays, e.g. extra-judicial slayings of boatloads of civilians off the coast of Venezuela, unprovoked attack on Iran etc.-  given he's never satisfied. His lust for power and retribution is insatiable and includes destroying our very democracy, i.e.

Trump Didn’t Merely Borrow Strongman Tactics: He Imported an Entire Doctrine Built to Kill Democracies.

The U.S. is just now realizing the extent of the 2024 election misfire, after Trump recklessly launched his war on Iran with little forethought, merely to appease his gargantuan ego. Worse, he doesn't even care about the pain inflicted on Americans by his folly, telling us to simply suck it up. 

The extent of Trump's egomaniacal assaults was perhaps best encapsulated in a January NY Times article (Trump Takes America’s ‘Imperial Presidency’ to a New Level )  which noted:

"Mr. Trump takes it upon himself to reinterpret a constitutional amendment and to eviscerate agencies and departments created by Congress. He dictates to private institutions how to run their affairs. He sends troops into American streets and wages an unauthorized war against nonmilitary boats in the Caribbean. He openly uses law enforcement for what his own chief of staff calls “score settling” against his enemies, he dispenses pardons to favored allies and he equates criticism to sedition punishable by death."

This is a flat-out, psychotic traitor whose fanciful planned 4th celebrations of his own Id (errr...identity)  are so inextricably tied into the 250th Independence holiday, that for me any kind of July 4th celebration is a non-starter. Given the magnitude of civil destruction in tandem with the distortion and deletion of U.S. history, I do not intend to participate in a bastardized, MAGA-fied 250th anniversary celebration conflating Dotard and America.

Posing as a dingbat contrarian on Real Time Friday night  - Bill Maher complained to his Dem Panel that "polls show only 18% of Dems are proud to be celebrating the nation's 250th." And so asking former Obama National Security aide Susan Rice and Sen. Chris Murphy:

 "Don't you think Dems would do better to just suck it up and forget Trump for July 4th? Because now you look like you don't really love the country and think Trump is more important"?

No, Bill, we think the nation is too important to devolve into a MAGA love fest for a traitor, featuring a cage match and drag race.  And to enlist any fraction of our attention. Also, bear in mind that prepping for his 80th birthday, Trump had already funneled millions meant for a bipartisan celebration of America to a partisan celebration of his wretched, senile self and personality cult. So he's already grifted away the financial basis and meaning of any authentic celebration of our national history. 

So pardon me if I am not proud of what this fiend and his minions have done, and won't be until they are all gone. For me ANY celebration under Trump would be showing total disrespect to Jacob and Conrad - who gave their blood in the Revolution for what we've now just given away. Simple enough?  

As Timothy Snyder (Professor at Munk School of Global Policy, Univ. of Toronto) put it Saturday on Velshi:

"Trump with his planned cage fights to celebrate the 4th, and putting his image everywhere, is trying to create the impression that he is unstoppable.  And this is what the celebration of the 250th anniversary of the nation means: glorification of him as the leader. That this is the best you can expect for this national holiday which he's identified with himself.  It's up to us to be like our predecessors, the first rebels, in 1776, to show this is not what the 250th anniversary means."

In line with that thinking I don't intend to watch a single firework in the sky or on TV.  I plan to have my nose buried in a book, most likely Bandy X. Lee's 'The Dangerous Case of Donald Trump'.  Oh, and maybe be listening to some (still relevant) folk music from the 60s - think of Joan Baez, Bob Dylan.  With the horrific re-election of Donald Trump by misled, gullible dimwits, this nation has much to commiserate - not celebrate. We had the chance to put this infernal criminal away and celebrate the first woman President in line with a genuinely meaningful 250th - but blew it. Now we reap the deformed, defiled results of a misbegotten choice. So be it.

Donald Trump looked at America’s 250th birthday and neurotically concluded that he’s the main attraction.

A celebration intended to honor the founding of the United States is rapidly being repackaged as a celebration of Trump himself: his movement, his grievances, his white supremacy, his misogyny, and his power.

Every new announcement, from the MAGA rallies to the vanity projects to the carefully choreographed spectacles on the National Mall and White House lawn, reinforces the same message: this is no longer about America turning 250. It’s about Trump making sure America spends its 250th birthday talking about Trump and the power of white men.

And if that sounds familiar, it should. Washington has seen this kind of political pageantry before.

Friends,

Trump often confuses himself with America, and America with himself.

Not surprisingly, his plan for celebrating the nation’s 250th anniversary is looking more and more like a celebration of Trump.

Trump’s face will be engraved on a $250 bill. It will be etched onto both sides of a celebratory gold coin. It’s already on passports issued this year. His signature is on dollar bills. He’s emblazoning his name on every edifice possible. If you still fail to get the point, his visage will soon be draped over federal buildings.

There’s also a 250th anniversary summer concert series on the National Mall. It was to have started June 25 with country music star Martina McBride. But McBride announced Thursday she wouldn’t perform, because, as she explained, although she had been “assured this was a nonpartisan event,” that assurance “turned out to be misleading.”

German chancellor's America warning: "Don't send your kids there"

Excerpt:

The warning came from Chancellor Friedrich Merz — a man who has spent decades believing in the American idea. A man who understands the indispensable role America played in preserving freedom in Europe. A man who knows what American power once represented to the world: stability, confidence, aspiration, seriousness, decency and order.

Now, he looks across the Atlantic Ocean, and sees something else entirely.

He sees rot.

He sees a country unraveling under the weight of corruption, vulgarity, fanaticism and madness. He sees a republic consumed by spectacle and poisoned by lies.

Bjorn Lomborg In WSJ Regards More Elderly Deaths As Biggest Factor In 'Hyping' Global Warming Heat Deaths

 

                                            Bjorn Lomborg - Climate provocateur


Bjorn Lomborg - he of the now discredited "Copenhagen Consensus" -  has escaped a lot of media scrutiny.  This is perhaps because he knows how to shovel the B.S.  Namely offering "adaptation" as the "less costly" alternative to things like lowering fossil fuel consumption, say by higher gasoline taxes.

In his latest WSJ propaganda column (‘Global Warming or Just Getting Old?’) June 3, p. A15) Lomborg goes one step further – postulating that yes, heat deaths are rising in Europe (82% since 1990 from Lancet study) but mortality rises sharply with age. In other words, given more elderly perish in heat waves, the significance of global warming heat deaths is hyped. So if the oldies just got ample air conditioning and stayed indoors they’d be ok – and global warming skeptics like Lomborg could ease up on their criticisms.

But the argument trotted out sounds disarmingly like the one from the Great Barrington Declaration during the Covid pandemic. That is, given the virus singled out oldies in particular (much less so the young)  given weaker immune systems. Hence, the Great Barington proponents like Scott Atlas,

                                                         Scott Atlas - 'herd immunity'

pushed for attaining herd immunity, rather than shutting schools, workplaces etc. down. Though this might necessitate more elderly be socially isolated in their homes to avoid infection.  But then the rest of the (younger, healthier) U.S. could enjoy the freedoms they were entitled to.  Of course, this was poppycock and we since learned the young were almost as likely to pay the price for contracting the disease, especially 'long Covid'.

Back to the climate issue: UAF climate scientist Gunther Weller (in 1980s) proposed a CO2 concentration of 600 ppm as the threshold value for the runaway greenhouse effect. More recent updates of Earth atmospheric system models show, however, that crossing a threshold of 600 ppm will not trigger a literal runaway greenhouse - but it will result in a radically altered, much warmer planet with devastating tipping points, e.g.

Five Major Climate Tipping Point Manifestations & What They Mean 

Further, these tipping points will lead to extreme climate conditions that will affect all humans on the planet not just the elderly. See e.g.,

How climate change is making some places too hot and humid to survive

In particular while exact “runaway” conditions (boiling seas) may not be reached extreme heat deaths will – such as occurred in Lyton, Oregon several years ago, e.g.

                                Hundreds lie on floor of Portland cooling center

Hence, Holman Jenkins recent chirping (‘Donald Trump, Climate Scientist’, May 30, p. A15) about Trump “being right all along” after the RCP 8.5 scenario was retired by the IPCC still doesn’t mean Trump is some kind of climate genius. No, oceans won’t boil away, and temperatures won't reach those of Venus, but dead bodies will surely pile up - both young and old. The point? Conditions don't have to reach the literal extreme for humans to pay a heavy toll in quality of life and life itself.

Excerpt:

At least 118 people died in the record heat wave that engulfed the Pacific Northwest in late June, when Portland and Seattle hit record highs of 116 degrees and 108, respectively. Lytton, a village in British Columbia, reached 121 degrees. A wildfire destroyed most of its homes, and at least two people died.

Local governments opened cooling centers and asked apartment managers to check on residents who might be at risk. Still, the heat strained the healthcare system in a part of the country unaccustomed to extreme temperatures.

It’s easy for us land dwellers to forget that we live on a water planet, more than 70% of it covered by a vast ocean. But we are entering an age—or more accurately, have created an age—when that fact will be impossible to ignore. With global climate change, the seas are rising, yes, but they are also warming, slowly but steadily, and that warmth is now reaching levels that can drive profound changes here on land. Many of those changes have begun, many are on display this year, and some will have seismic consequences going forward.

Almost as shocking as the scale of these changes are the Trump administration’s efforts to dismantle the very scientific instruments that enable us to understand them. We’ll get there. But first, a little immersion into our water planet to better understand what it means to overheat it and force the ocean to compensate.

The Extremists Behind The Phony 'Religious Freedom' Bill

 


"Many people in this country consider America to be a "Christian" nation. If only it were. A truly Christian nation would put the words of Jesus into their policies and actions. I see very little of that from this administration and, if one were honest, the history of the U.S. is filled with policies anathema to Christianity. Slavery, ethnic cleansing of the Indian nations, lynchings after Reconstruction, Jim Crowe, to name just a few."- NY Times comment


Unmentioned thus far in the mainstream media is the chilling aspect of Trump's Project 2025 to take over our secular government and transform it into a theocracy.  The vehicle to achieve this nefarious, anti-constitutional end is none other than Trump's 'Religious Liberty Commission' (RLC)  launched last spring.

The aim of the extremists behind it - some of whom are shown above- is basically to redefine religious freedom as unchecked privilege for one narrow Christian cult based on Christian Nationalism. An even more dangerous ambition is to attempt to equate Christian Nationalism with patriotism.

 The RLC members shown in the graphic above are a who's who of career zealots kept afloat Shadow Network occupying its 18-member board. Each has a long record of expanding, advancing and implementing the Xtian Nationalist agenda including imposing their brand of Christianity on public schools and government institutions and rolling back women's rights.  

Among the worst offenders and reprobates are:

- Texas Lt. Governor Dan Patrick, a vocal supporter of coercive religion in public schools and faith-based legislation

- Paula White-Cain, head of the White House Faith office who once compared Trump to Jesus and is a long time Xtian Nationalist power broker.

-Ben Carson, former HUD Secretary, who believes Islam is "incompatible with the Constitution"  

Apart from a single Rabbi, the RLC's core leadership has no representation from any other religious groups- including Christians and Jews who don't support the Xtian Nationalist agenda.

Indeed, if these extremists could read as well as they bellow about their origin fables, they'd see that Declaration itself repudiates the claim of a nation founded on Judeo-Christian values.  To be specific, the Declaration of Independence cites 4 references that supposedly support the Judeo-Christian myth. However, not a single one mentions: Jesus Christ, Yahweh, or a specific Christian version of God. At most they reflect the Founders who wrote it as adherents of Deism.  This is the belief that a supernatural being or entity created the universe but then departed and plays no role in future events. Somewhat like a 'watchmaker' who makes is universal watch, sets it in motion then walks away.

Finally, the ratification of the Treaty of Tripoli, e.g. 

Treaty of Tripoli - Wikipedia

  Put the final stamp of secularism on the national entity which was the United States.  As noted above in the Wikipedia entry, the key words of the Treaty are:

"As the Government of the United States of America is not, in any sense, founded on the Christian religion; as it has in itself no character of enmity against the laws, religion, or tranquility, of Mussulmen; and, as the said States never entered into any war, or act of hostility against any Mahometan nation, it is declared by the parties, that no pretext arising from religious opinions, shall ever produce an interruption of the harmony existing between the two countries"  

While Jefferson, Madison, Franklin et al could have well chosen to root their appeals, entitlements, endowments etc. in Jesus Christ, or Yahweh or a similar recognizable Judeo-Christian being, they did not. They were Deists, so no wonder. This ought to telegraph emphatic differences to the Trump religious extremists, but they are so fixed on seeing what they want they miss the 'forest for the trees'.

Why A Change To The Standard Lorentz Transformation Is More Advantageous for Theoretical Physics

 In previous posts (on special relativity) we saw the format of the basic Lorentz transformation, e.g.:

x' = (x - vt)/ Ö[1 - v2/c2

t' = (t - vx/c2 )/ Ö[1 - v2/c2

For x' and t' to be real numbers we required:  v <  c   

Further, we expect all the laws of physics to be invariant under these transformations. Recall  in plane Euclidean geometry rotations of a coordinate system are represented by matrices, i.e. in two dimensions x, t: 

A = A  (Θ) =

(a11.......a12)
(a21......a22)  

where Θ is the angle by which the system rotates.  A matrix defined by the special Lorentz transformation *  can then be written:

(1/Ö [1 - v2/c2]                 - v / Ö[1 - v2/c2])

- v / cÖ] [1 - v2/c2]        1/ Ö[1 - v2/c2])  

But consider if instead of the initial 2D coordinates (x and t and x' and t'),  we take: x and ict, and x' and ict' - where we have introduced the imaginary number: i = Ö- 1

The earlier transformations then assume the form:

x' = 1/ Ö[1 - v2/c2]   (x +   iv/c  ict)

ict'  =  1/ Ö[1 - v2/c2]   (- ivx/c  +  ict)

Yielding the new matrix:

(1/Ö [1 - v2/c2]                (iv/c)   1 / Ö[1 - v2/c2])

( - iv / c)   1 /Ö] [1 - v2/c2]          1/ Ö[1 - v2/c2])


The above can then be transformed into simpler matrices in terms of:

cos iΘ  =   cosh Θ   =   1/ Ö[1 - v2/c2

sin iΘ  =   -i sin h Θ   =   ( iv / c)  (1/ Ö[1 - v2/c) 

Leading to the more compressed trig matrix:
.  
(cos iΘ..... sin iΘ)
(-sin iΘ)...cos iΘ)

Which can be thought of as rotation through an imaginary angle of the (x, ict) coordinate system. This is often a  more helpful form in formulating physical laws. 

Specifically, this is incredibly useful in theoretical physics for two main reasons: turning oscillating integrals into convergent ones and unifying quantum mechanics with statistical mechanics.

Digging deeper: In real i.e. (Lorentzian) time, the action factor (exp  iS/h) generates rapidly oscillating waves that are notoriously difficult to integrate, making rigorous calculations almost impossible.

By substituting time (t) with imaginary time (ict)), the Lorentz metric:

ds2 =  -  dt2  +    dx 

becomes a purely Euclidean metric :

ds2 =  -  d2  +    dx2

Thereby the oscillating factor (exp  iS/h) transforms into the exponentially decaying factor (exp  -iS/h)

 Which makes the mathematical functions well-behaved and convergent, allowing physicists to rigorously solve associated path integrals.
