Billionaire Peter Thiel will lead a private, four-part lecture series in San Francisco exploring the Antichrist through theology, history, literature, and politics, drawing on thinkers like René Girard, Francis Bacon, and Jonathan Swift.

Hosted by the nonprofit Acts 17 Collective, the talks—scheduled from Sept. 15 to Oct. 6 at The Commonwealth Club—will be off-the-record and require full-series attendance.

The event includes moderated and audience Q&A sessions, reflecting Thiel’s interest in the intersection of Christian faith, technology, and society, the Christian Post has reported.
