Abstract
This article critically assesses an account of religious liberty often associated with several legal and political philosophers: Ronald Dworkin, John Rawls, and Christopher Eisgruber and Lawrence Sager. Calling it the Religion as Comprehensive Doctrine approach, the author contrasts it with an account often attributed to John Locke and the American Founders Thomas Jefferson and James Madison, the Two Sovereigns approach. He argues that the latter provides an important corrective to RCD’s chief weakness: RCD eliminates from our vision those aspects of religious belief and practice that most conventional religious believers would consider essential to their faith.
