We show how Causal Field Theory (CFT) can be transcribed from the conventional Minkowski formulation to the Light-Coneframework and how nonperturbative vacuum effects can be incorporated. The combination of the divergence free CFT with nonperturbative LC-physics opens a road to a mathematically sound renormalization of nonperturbative theories.
