  The classically perfect action of QCD requires no tuning to get the pion
massless in the broken phase: the critical bare mass $m_q^c$ is zero. Neither
the vector nor the flavour non-singlet axial vector currents need
renormalization. Further, there is no mixing between four-fermion operators in
different chiral representations. The order parameter of chiral symmetry
requires, however, a subtraction which is given here explicitly. These results
are based on the fact that the fixed point action satisfies the Ginsparg-Wilson
remnant chiral symmetry condition. On chiral symmetry related questions any
other local solution of this condition will produce similar results.
