Courts and scholars across jurisdictions increasingly identify personal autonomy as the primary rationale for the right to religious freedom. But there are tensions between autonomy on one hand, and religious belief, practice and proselytism on the other. This paper will focus on two tensions which have unappreciated implications for religious freedom jurisprudence, particularly that of the ECHR. The first tension stems from the resistance of some religious beliefs to revision. The second stems from the manipulative nature of some modes of religious proselytism. This paper argues that, given these tensions, the protection currently offered to religious beliefs, practices and proselytism by the right to religious freedom cannot be justified by reference to the value of autonomy. This finding has significant implications for the justification of the right to religious freedom.
