Not so. Church-style lambda calculus is the one where types matter; Curry-style is the one that ignores types and evaluates as if it were the untyped lambda calculus.
Church encodings are based on the untyped LC rather than Church's simply-typed LC however, which is why they don't typecheck with Hindley--Milner.
