WebChurch's Theorem states: For suitable L, there exists no effective method of deciding which propositions of L are provable. The statement is proved by Church (I, last paragraph) with the special assumption of w-consistency, and by Rosser (IV, Thm. III) with the special assumption of simple consistency. These proofs will be referred to as CC and WebChurch's Theorem states: For suitable L, there exists no effective method of deciding which propositions of L are provable.

WebStrict Formalism. Church's Thesis is nowadays generally accepted, but it can be argued that it does not even "make sense", on the grounds that mathematics cannot be allowed to deal with informal concepts of any kind.. That is, mathematics is the study of formal systems. This is the view of strict formalism..

This was done by Alonzo Church in 1935 with the concept of "effective calculability" based on his λ-calculus, and by Alan Turing the next year with his concept of Turing machines. Turing immediately recognized that these are equivalent models of computation. The negative answer to the Entscheidungsproblem was then given by Alonzo Church in 1935–3… fixer upper outdoor shower
