Canon 5: “It seemed good that whosoever
should say that the grace of
justification was given to us only
that we might be able more readily by
grace to perform what we were ordered
to do through our free will; as if
though grace was not given, although
not easily, yet nevertheless we
could
even without grace fulfill the divine commandments, let him be
anathema.
For the Lord spoke concerning the
fruits of the commandments when he
said: “Without me you can do nothing'
(John 15.5), and not 'Without me you
could do it but with difficulty.’”
