Not to Caesar but to Peter

We invite you to join author William Haun for the launch of his book, Not to Caesar but to Peter: Remembering why the Catholic Church is a perfect society, on Wednesday, October 14 at 6:00 PM EDT. This program will be offered both in-person at the CIC and virtually through a YouTube livestream.

About the Not to Caesar but to Peter:

Drawing on the Catholic Church’s self-understanding as a complete, self-sufficient (in the Aristotelian sense, “perfect”) society, William Haun’s new book explains how the Catholic Church’s claimed legal authority provides a stable basis for religious liberty in civil law. If the Church were to remember this traditional claim of her legal authority, she could improve U.S. law’s commitment to protecting religious liberty for religious institutions and communities. In so doing, the Church can both grow in American life and, by being who she truly is, respond to common misunderstandings about the proper relationship between the Catholic Church and the state that threaten her presence in public life—ranging from those who see the Church as just another social club in civil society, to those who treat the Church as an instrument of power that should be “integrated” with the state “from within.”

Not to Caesar but the Peter will be on sale at the CIC bookstore in October.
