Summary:Geometric interpretation of the continuum regularization program is found in a Schwinger-Dyson formulation of coordinate-invariant regularization. Introductory application of the general formulation is given for the regularized non-linear sigma model and regularized euclidean gravity. A Schwinger-Dyson bonus, conceptually independent of the regularization, is noted in the case of euclidean gravity: Due to the differential character of the formulation, difficulties usually associated with unbounded action are bypassed, at least in weak coupling.
