The Batalin-Vilkovisky formalism for field theories with gauge symmetries is revisited. It is shown that the step from the classical theory to the quantum theory, which is usually discussed via the path integral, can be performed by the renormalized time ordering operator which is obtained by a generalization of Epstein-Glaser renormalization.
