Theological noncognitivism

Theological noncognitivism is the position that religious language – specifically, words such as "God" – and "Allah" – are not coherently defined. It is sometimes considered synonymous with ignosticism and igtheism.
One argument holds to the claim that definitions of "God" and "Allah" are irreducible, self-instituting relational, circular. For example, a sentence stating that "God is He who created everything, apart from Himself", is seen as circular rather than an irreducible truth.
