A very careful definition worthy of a lot of reflection:
Non-Christian religions are sovereignly directed, variegated and dynamic human idolatrous distortions of divine revelation behind which evidence demonic deception.
Being antithetically against yet practically dependent upon the truth of the Christian worldview, non-Christian religions are ’subversively fulfilled’ in the gospel of Jesus Christ.
