   Note: In some churches, as the Dutch Reformed in America, a
         consistory is composed of the minister and elders of an
         individual church, corresponding to a Presbyterian
         church session, and in others, as the Reformed church
         in France, it is composed of ministers and elders,
         corresponding to a presbytery. In some Lutheran
         countries it is a body of clerical and lay officers
         appointed by the sovereign to superintend
         ecclesiastical affairs.
