Would Islam exist without Christianity?

Reflection

Asking whether Islam would exist without Christianity raises an interesting historical and theological question, since Islam emerged in a seventh century context where Christian and Jewish communities, texts, and ideas were already well established across Arabia and the wider Middle East. Islamic scripture and tradition explicitly engage with figures such as Jesus, Mary, and Abraham, though interpreting them differently from Christian teaching. Historically speaking, it seems unlikely that Islam would have taken the same shape without the prior presence of Christian and Jewish thought in the region. Theologically, Christians hold that ultimate truth is found in Christ alone, while still engaging honestly with the historical reality that religions do not develop in isolation from one another. This kind of question calls for careful historical thinking alongside clear theological conviction, rather than either dismissing the question or overstating the connections.

Questions to sit with

• What surprises you about the historical relationship between early Christianity and the origins of Islam?
• How do you hold historical curiosity and theological conviction together on questions like this?
• Why does it matter to engage such questions honestly rather than defensively?
