Christianity and Islam are the world`s two largest religions, together accounting for over half the global population. They share deep Abrahamic roots — a common ancestor in Abraham, a commitment to ethical monotheism, a belief in revelation, prophecy, and final judgement. Yet they also hold fundamental theological differences, particularly regarding the nature of God, the status of Jesus, and the authority of their respective scriptures. This lesson examines the Abrahamic connections, the portrayal of Jesus in Islam, the history of dialogue and conflict, the significance of Nostra Aetate, and the key theological differences that make this one of the most important and complex interfaith relationships in the contemporary world.
Christianity and Islam are both Abrahamic religions — they trace their spiritual ancestry to Abraham (Ibrahim in Arabic), the patriarch who, according to both traditions, responded to the call of the one true God and established the pattern of faithful monotheism.
| Belief | Christianity | Islam |
|---|---|---|
| Monotheism | One God (Trinity) | One God (Tawhid — absolute oneness) |
| Creation | God created the world ex nihilo | God (Allah) created the world by divine command |
| Revelation | God reveals through Scripture and ultimately through Christ | God (Allah) reveals through the Qur`an, the final revelation |
| Prophecy | Old Testament prophets; Christ as fulfilment | A succession of prophets from Adam to Muhammad (the "Seal of the Prophets") |
| Final judgement | Christ will return to judge the living and the dead | Yawm al-Qiyamah (Day of Judgement); all will be judged |
| Afterlife | Heaven and hell | Jannah (paradise) and Jahannam (hell) |
| Ethics | Love of God and neighbour; the Decalogue | Submission to Gods will; the Five Pillars; Shariah |
In the Bible, Abraham is the father of Isaac (ancestor of the Israelites) and Ishmael (ancestor of the Arabs). The Quran honours Ibrahim as a *hanif* — a pure monotheist who submitted entirely to God before the time of Judaism, Christianity, or Islam. The Quran presents Ibrahim as the model of islam (submission to God) and identifies the Kaba in Mecca as the house of worship built by Ibrahim and Ismail.
One of the most fascinating aspects of the Christian-Islamic relationship is the high status that Islam accords to Jesus (`Isa ibn Maryam — Jesus son of Mary).
The Quran mentions Jesus by name twenty-five times and devotes more attention to him than to any other prophet except Muhammad. Key Quranic affirmations about Jesus:
| Qur`anic Teaching | Reference |
|---|---|
| Jesus was born of the Virgin Mary (Maryam) | Surah 3:47; 19:16–35 |
| Jesus is a prophet and messenger of God | Surah 4:171; 5:75 |
| Jesus performed miracles by God`s permission | Surah 3:49; 5:110 |
| Jesus is called "the Messiah" (al-Masih) | Surah 3:45; 4:171 |
| Jesus is "a Word from God" (Kalimatullah) | Surah 3:45; 4:171 |
| Jesus is "a Spirit from God" (Ruhullah) | Surah 4:171 |
| Jesus was not crucified — it was made to appear so | Surah 4:157–158 |
| Jesus was not divine — God has no son | Surah 4:171; 5:72; 19:35 |
| Jesus will return before the Day of Judgement | Hadith traditions (not explicitly in Qur`an) |
The deepest theological divide between Christianity and Islam concerns the identity of Jesus:
| Christianity | Islam |
|---|---|
| Jesus is the Son of God, the second person of the Trinity, truly God and truly human | Jesus is a human prophet — one of the greatest, but entirely human |
| Jesus is God incarnate — the eternal Word made flesh (John 1:14) | God does not become incarnate; the Incarnation is rejected as shirk (associating partners with God) |
| Jesus died on the cross and was raised from the dead | Jesus was not crucified; God saved him and raised him to heaven |
| The Trinity — Father, Son, and Holy Spirit | Tawhid — God is absolutely one; the Trinity is rejected as a form of polytheism |
Key Definition: Tawhid — The Islamic doctrine of the absolute oneness and unity of God. Tawhid is the most fundamental principle of Islamic theology and is directly opposed to the Christian doctrine of the Trinity, which Muslims regard as compromising the unity of God.
The Christian-Islamic relationship has been marked by both creative dialogue and devastating conflict.
The earliest encounters were shaped by military expansion. The Islamic conquests of the seventh and eighth centuries brought vast territories — including the Christian heartlands of the Middle East, North Africa, and eventually Spain — under Muslim rule. Christians living under Muslim rule (dhimmis) were generally granted a degree of religious freedom in exchange for paying a special tax (jizya), but they were second-class citizens.
The Crusades represent the most violent chapter in Christian-Islamic relations. Launched by Pope Urban II in 1095, the Crusades were military campaigns to recapture the Holy Land from Muslim control. The sack of Jerusalem in 1099, during which Crusaders slaughtered Muslim and Jewish inhabitants, remains a powerful symbol of religious violence. The Crusades left a legacy of mutual suspicion that continues to affect the relationship today.
