Usually, even a non-Christian knows something about the earth, the heavens, and the
other elements of this world, about the motion and orbit of the stars and even their size
and relative positions, about the predictable eclipses of the sun and moon, the cycles of
the years and the seasons, about the kinds of animals, shrubs, stones, and so forth, and
this knowledge he holds to as being certain from reason and experience. Now, it is a
disgraceful and dangerous thing for an infidel to hear a Christian, presumably giving the
meaning of Holy Scripture, talking non-sense on these topics; and we should take all
means to prevent such an embarrassing situation, in which people show up vast ignorance
in a Christian and laugh it to scorn. The shame is not so much that an ignorant individual
is derided, but that people outside the household of the faith think our sacred writers held
such opinions, and, to the great loss of those for whose salvation we toil, the writers of
our Scripture are criticized and rejected as unlearned men. If they find a Christian
mistaken in a field which they themselves know well and hear him maintaining his
foolish opinions about our books, how are they going to believe those books in matters
concerning the resurrection of the dead, the hope of eternal life, and the kingdom of
heaven, when they think their pages are full of falsehoods on facts which they themselves
have learnt from experience and the light of reason? Reckless and incompetent
expounders of holy Scripture bring untold trouble and sorrow on their wiser brethren
when they are caught in one of their mischievous false opinions and are taken to task by
those who are not bound by the authority of our sacred books. For then, to defend their
utterly foolish and obviously untrue statements, they will try to call upon Holy Scripture
for proof and even recite from memory many passages which they think support their
position, although “they understand neither what they say nor the things about which they
make assertion.
