  In this work we derive the version of the Equivalence Theorem that applies
when the symmetry breaking sector of the Standard Model is described by a
general chiral lagrangian. The demonstration is valid for renormalized fields
for any value of the gauge parameter (in $R_{\xi}$ gauges) and any
parametrization of the coset space. It is based in the absence of gauge
anomalies which makes it possible to build an (anti)-BRS invariant chiral
lagrangian in terms of the renormalized fields and therefore to use the
corresponding Ward identities to obtain the theorem.
