Secondly, All propositions whereof the mind, by the use of its natural
faculties, can come to determine and judge, from naturally acquired
ideas, are matter of reason; with this difference still, that, in those
concerning which it has but an uncertain evidence, and so is persuaded
of their truth only upon probable grounds, which still admit a
possibility of the contrary to be true, without doing violence to the
certain evidence of its own knowledge, and overturning the principles of
all reason; in such probable propositions, I say, an evident revelation
ought to determine our assent, even against probability. For where the
principles of reason have not evidenced a proposition to be certainly
true or false, there clear revelation, as another principle of truth and
ground of assent, may determine; and so it may be matter of faith, and
be also above reason. Because reason, in that particular matter, being
able to reach no higher than probability, faith gave the determination
where reason came short; and revelation discovered on which side the
truth lay.
10. In Matters where Reason can afford certain Knowledge, that is to be
hearkened to.
Thus far the dominion of faith reaches, and that without any violence or
hindrance to reason; which is not injured or disturbed, but assisted and
improved by new discoveries of truth, coming from the eternal fountain
of all knowledge. Whatever God hath revealed is certainly true: no doubt
can be made of it. This is the proper object of faith: but whether it be
a DIVINE revelation or no, reason must judge; which can never permit the
mind to reject a greater evidence to embrace what is less evident,
nor allow it to entertain probability in opposition to knowledge and
certainty. There can be no evidence that any traditional revelation is
of divine original, in the words we receive it, and in the sense we
understand it, so clear and so certain as that of the principles of
reason: and therefore NOTHING THAT IS CONTRARY TO, AND INCONSISTENT
WITH, THE CLEAR AND SELF-EVIDENT DICTATES OF REASON, HAS A RIGHT TO BE
URGED OR ASSENTED TO AS A MATTER OF FAITH, WHEREIN REASON HATH NOTHING
TO DO. Whatsoever is divine revelation, ought to overrule all our
opinions, prejudices, and interest, and hath a right to be received with
full assent. Such a submission as this, of our reason to faith, takes
not away the landmarks of knowledge: this shakes not the foundations
of reason, but leaves us that use of our faculties for which they were
given us.
11. If the Boundaries be not set between Faith and Reason, no Enthusiasm
or Extravagancy in Religion can be contradicted.
