A new, comprehensive relativistic many-body approach utilizing the Cou
lomb gauge QCD Hamiltonian is advanced for hadron physics. The formali
sm properly incoporates renormalization for regularizing divergences a
nd also manifests the Nambu-Goldstone realization of chiral symmetry.
Using standard many-body techniques, calculations for the constitutuen
t quark, gluon condensates and masses and gluon spectrum are found to
be in good agreement with QCD sum-rules and quenched lattice gauge res
ults.
