A functional formulation of quantum field theory is presented consisting in a unification and generalization of the three- and four-dimensional functional methods. The basis for the formulation are the generating functionals for the mass shell S-matrix elements and their out of the mass shell generalizations restricted by the conditions of unitarity and causality. The notions of Hilbert space (of state vectors) and field operators in this space do not occur (at least not as primary notions) and, therefore, also the corresponding assumptions (as e.g. the asymptotic condition or the assumption about completeness) are avoided.
