Chapter II. The Principle and Idea of Orthodoxy Stated and Examined
§ 1 The Principle of Orthodoxy Defined
The principle of Orthodoxy is, that there is one true system of Christian doctrine, and that all others are false; that this system can be, and has been, so stated in words as to distinguish it from all the false systems or heresies; and that this true system of doctrine is the one which is now held, and always has been held, by the majority of Christians; and, finally, that the belief of this system is, as a rule, essential to salvation—so that those who may be saved, while not accepting it, will be saved (if at all) by way of exception, and not according to rule.
