A formula describing finite renormalizations is derived in the Epstein‐Glaser formalism and an explicit calculation of finite counterterms in Φ 4 ‐theory is performed. The Zimmermann identities and the action principle for changes of parameters in the interaction are presented independent of the adiabatic limit.
