The Catholic Church also
understands the need to interpret
correctly the truth of all of
the Bible. The Bible warns us that
there will be incorrect
interpretation without authority. All
interpretations of a
scripture cannot be equally true (it is contrary
to the nature of truth); some
interpretations of the same scripture
are mutually incompatible
(e.g., Mt 16:16; Jn 6). Hence there
must be an authority to whom
truth and error can be appealed.
2 Peter 3:16
In them (Paul's letters) there are some things hard to
understand that the ignorant and unstable distort to
their own destruction, just as they do the other
scriptures.
