We present an exploratory study of a gauge-invariant non-perturbative renormalization technique. The renormalization conditions are imposed on correlation functions of composite operators in coordinate spare on the lattice. Numerical results for bilinears obtained with overlap and 0(a)-improved Wilson fermions are presented. The measurement of the quark condensate is also discussed.
