Priesthood of all believers
The priesthood of all believers is the common priesthood of all Christians (a concept broadly accepted by all churches), while the term can also refer to a specific Protestant understanding that this universal priesthood precludes the ministerial priesthood (i.e., holy orders) found in some other churches, including Catholicism and Eastern Orthodoxy. The inclusionary Catholic version proposes a common priesthood that is different from both holy orders and the priesthood of Christ.
