Christianity used to burn heretics. It used to execute apostates. It used to torture people into confession of faith. It no longer does any of these things — not because Christian theology changed but because the political power of Christian institutions was systematically checked by the Enlightenment, by the separation of church and state, by the development of liberal political theory, and by the erosion of institutional religious authority in Western societies.
The objection to Islam is often stated this way: Islam has not had that reckoning. It has not been tamed. Its political and legal institutions still claim divine sanction for punishments that the Western world has moved beyond. And if the Enlightenment could not change the theology of Christianity — if what changed was power, not doctrine — then waiting for Islamic theology to reform itself is waiting for the wrong thing.
This is a serious and historically informed objection.
What actually happened to Christianity
The objection is correct that Western Christianity was reformed by political and social forces rather than theological ones. But it misses an important detail: the internal resources for reform were already present in Christian theology. The Sermon on the Mount did not endorse the Inquisition. The New Testament’s emphasis on conscience, grace, and inner transformation was always in tension with coercive institutional religion. What the Enlightenment did was shift the power balance so that those internal theological resources could operate against the institutions that had suppressed them.
The same internal resources exist in Islam. The Quran’s repeated insistence on the importance of reason, on the distinction between genuine and coerced faith, on the universality of God’s mercy, on the personal nature of the relationship between a soul and its Creator — these have always been in tension with the political Islam that produced apostasy laws and coercive enforcement. What has been missing is not the theological resources. It is the social and political conditions that would allow those resources to operate.
The Enlightenment that is already happening
The objection that Islam has not had its Enlightenment is empirically questionable. What is happening in Muslim-majority societies — the Arab Barometer data, the Iranian surveys, the scale of quiet departure from religious practice — looks very much like a secularisation process driven by exactly the forces that drove it in the West: urbanisation, education, access to alternative information, and the experience of political Islam’s failures in governance.
This process is not publicised, because making it visible is dangerous. But it is happening. The person who has quietly left Islam in Tehran or Cairo or Kuala Lumpur is part of it. The scale of hidden non-belief documented in surveys of Muslim-majority countries represents a transformation in religious practice that is, on any historical comparison, extremely rapid.
What this means for the tradition
The objection to Islam from the Enlightenment comparison is partly a prediction that has not yet been borne out — and partly an observation about a process that is in progress. The question is not whether Islam will change. Traditions change. The question is whether what remains after the political and coercive elements are stripped away contains something genuine — something that is not merely institutional power dressed in theological language, but a real account of God, humanity, and the relationship between them.
That question is not settled by the history of political Islam. It is settled by examining the foundational claims on their own terms — which is what this entire inquiry is engaged in.
