A controversial former Roman Catholic archbishop who was excommunicated earlier this year has told American Catholics there is “no question” they have to vote for former President Donald Trump — because Vice President Kamala Harris is “an infernal monster who obeys Satan.”

Carlo Maria Vigano, who served as the Vatican’s ambassador to the US from 2011 until 2016, penned a fiery open letter to American Catholics in which he said this November they must “choose between two radically opposed ways of conceiving the government of your Nation.”

“The choice is between a conservative President, who is paying with his very life for his fight against the deep state, and an infernal monster who obeys Satan,” Vigano wrote.

“For a Catholic, there can be no question: voting for Kamala Harris is morally inadmissible and constitutes a very grave sin. Nor is it morally possible to abstain, because in this war declaring oneself neutral means allying oneself with the enemy,” he said.

He continued that voting for Trump “means firmly distancing ourselves from an anti-Catholic, anti-Christian and anti-human vision of society. It means stopping those who want to create a hellish dystopia that is even worse than the one announced by George Orwell.”

Vigano was excommunicated from the Catholic Church in July for his outspoken criticism of Pope Francis and modern church reforms made at the Second Vatican Council in the 1960s.

His letter contains numerous references to numerous conspiracy theories, including references to the “deep state,” calling the 2020 presidential election “the fraud of 2020” and suggesting that the world governments engineered climate change to “to make the global warming fraud credible.”

The former Archbishop of Ulpiana also touched on hot cultural issues in the United States like “woke” ideology and sexually explicit material being taught in public schools, which he called “dens of indoctrination and corruption from kindergarten onwards.”

Vigano blasted Harris “a puppet” controlled by former President Barack Obama, former Secretary of State Hillary Clinton and liberal billionaire George Soros.

He called Trump “the only possible choice to counter the globalist coup that the woke Left is about to implement definitively, irreparably, and with incalculable damage for future generations.” 

“We want Christ to reign, and we proclaim it with pride: Christ is King! They want the Antichrist to reign, whose tyranny is made of chaos, war, disease, famine, and death,” Vigano added.

A survey from the Pew Research Center published last month revealed that 52% of Catholics plan to vote for Trump, while 47% back Harris.
