WASHINGTON (AP) — President Donald Trump refused to apologize to Pope Leo XIV on Monday after criticizing the pontiff for his opposition to the war in Iran — and he sought to explain away a now-deleted social media post depicting himself as Jesus by saying he had thought the image was of him as a doctor.

Trump was asked about his comments toward the U.S.-born head of the Catholic Church, as well as the post depicting himself as a saint-like healer, in a hastily called question-and-answer session with reporters at the White House.

“He was very much against what I’m doing with regard to Iran, and you cannot have a nuclear Iran. Pope Leo would not be happy with the end result,” Trump said, adding, “I think he’s very weak on crime and other things, so I’m not” going to apologize.

“He went public,” the Republican president added. “I’m just responding to Pope Leo.”

That response followed Leo pushing back on Trump’s broadside against him the previous evening, telling reporters that the Vatican’s appeals for peace and reconciliation are rooted in the Gospel and that he doesn’t fear the Trump administration.

“To put my message on the same plane as what the president has attempted to do here, I think is not understanding what the message of the Gospel is,” Leo told The Associated Press aboard the papal plane en route to Algeria. “And I’m sorry to hear that, but I will continue on what I believe is the mission of the church in the world today.”

The back-and-forth between the world’s two most influential Americans served to deepen a burgeoning schism as the U.S. war in Iran stretched into its seventh week.
