Now by Liberalism I mean false liberty of thought, or the exercise of thought upon matters, in which, from the constitution of the human mind, thought cannot be brought to any successful issue, and therefore is out of place. Among such matters are first principles of whatever kind; and of these the most sacred and momentous are especially to be reckoned the truths of Revelation. Liberalism then is the mistake of subjecting to human judgment those revealed doctrines which are in their nature beyond and independent of it, and of claiming to determine on intrinsic grounds the truth and value of propositions which rest for their reception simply on the external authority of the Divine Word.
