For months, Peter Thiel, the right-wing tech billionaire, has warned of what he sees as an imminent threat from the Antichrist, an entity portrayed in some Christian traditions as one of Jesus’ ultimate enemies.

Mr. Thiel, an investor in artificial intelligence, says he is drawing on biblical prophesies to warn of an Antichrist who will promise safety from existential risks like nuclear war, climate change and artificial intelligence only to bring about something worse: one-world, totalitarian government.

Now, Mr. Thiel is encountering resistance from Christian thinkers in the Roman Catholic Church, just as he tries to build support for his ideas in the church’s backyard in Rome.

This week, Mr. Thiel arrived in Rome to deliver four lectures on the Antichrist. The series, which began on Sunday, is exploring how “occult forces are ceaselessly at work, intent on destroying what remains of the West,” according to the conservative Christian group hosting him.

Mr. Thiel held similar lectures in San Francisco last year and in Paris in January, prompting relatively little reaction from Christian thinkers. But proximity to the Vatican appears to have prompted some Roman Catholic commentators to issue a more sustained response. In the “American heresy” essay, the Rev. Paolo Benanti, an adviser to the Vatican on A.I., described Mr. Thiel’s vision as “disturbing.”
