The main differences between Islam and Christianity

Monotheistic religions, such as Islam and Christianity, are founded on the worship of a single God and on divine revelation transmitted through sacred texts and prophets. Here are the main similarities and differences

We have already looked in the past at the main differences between Judaism and Christianity. In this article, however, we look at what divides and unites two other great monotheistic religions: Islam and Christianity. Understanding the differences and similarities between two religions is the starting point for creating a constructive and enriching dialogue even between people who are culturally very distant from one another. Despite their numerous differences, Islam and Christianity share many points of contact that reflect their common Abrahamic origin.

Monotheistic religions have profoundly influenced history, culture and societies throughout the world. Understanding the similarities and differences between Islam and Christianity can promote greater tolerance and mutual respect between Muslims and Christians, contributing to a more constructive and peaceful interfaith dialogue.

The Abrahamic Religions

The main Abrahamic religions are Judaism, Christianity and Islam. These religions are so called because they originate from Abraham, considered the patriarch and the first monotheist. This common starting point helped to create a basis of shared beliefs, but it also led to distinct and sometimes divergent theological developments. For Christians, as for Jews, Abraham’s descendants are identified with Isaac, chosen by God, while Muslims consider Ishmael, Abraham’s firstborn son, born to him with the slave Hagar before Sarah became pregnant, to be more important. In the Qur’an, it is Ishmael whom Abraham is about to sacrifice.

Judaism, Christianity and Islam share common roots and certain fundamental principles, while differing significantly in the concept of God, sacred texts, key figures, religious practices and doctrines of salvation.

All three religions believe in one almighty, all-knowing and merciful God and are based on sacred texts. Judaism has the Torah, Christianity has the Bible (composed of the Old and New Testaments), and Islam has the Qur’an.

The Abrahamic religions recognise the importance of prophets. Many prophets are common to all three faiths, such as Abraham, Moses and David.

All three religions have a series of laws and commandments that guide the moral and spiritual life of believers. For example, the Ten Commandments are a fundamental part of Judaism and Christianity, while Islam has Sharia, which includes laws derived from the Qur’an and the Hadith, accounts related to the prophet Muhammad, concerning what he said and did.

There is also a shared belief in the Day of Judgement, when God will judge humanity. This belief varies in its details but is an important component of all three faiths.

Similarities between Islam and Christianity

To begin with, we can state that Islam and Christianity have the largest number of followers in the world: approximately 1,800 million for the former and 2,300 million for the latter.

Secondly, both followers of Islam and those of Christianity consider their own religion monotheistic. Both faiths believe in one God and emphasise the importance of divine revelation, transmitted through their respective sacred texts: the Qur’an for Muslims and the Bible for Christians. This shared adherence to monotheism is one of the fundamental similarities between Islam and Christianity.

The two faiths also share the same place of origin, the Middle East. This region played a crucial role in the development of monotheistic religions, profoundly influencing the history and culture of the civilisations that flourished there. It was precisely their common roots in the Middle East that led to various similarities and differences between the two faiths, with important historical and theological implications.

The theological differences between Islam and Christianity are profound and often complex. One of the main divergences concerns the concept of God. As we have said, both religions, Islam and Christianity, believe in one God whose Word is conveyed through a written text.

In Christianity, however, God is the Trinity: Father, Son and Holy Spirit, three distinct persons united in a single divine essence, one God. God is seen as the creator, a merciful Father, who revealed Himself to humanity through the coming of Christ and the gift of the Holy Spirit. Jesus is the Redeemer, a symbol of hope and bearer of Salvation.

In contrast, Islam sees God (Allah) as One and Only, and this concept of the unity and oneness of God is at the heart of the Islamic faith. The Trinity is rejected because it breaks the unity of God and is considered a form of polytheism. They consider Jesus a prophet, not divine, while the Holy Spirit is identified with the angel Jibril (Gabriel), entrusted with transmitting Revelation to the prophets, without attributes of divinity. Muhammad is considered the last and greatest of the prophets, bearer of Allah’s final message to humanity.

Furthermore, salvation is understood differently in the two religions.

For Christians, salvation is attained through faith in Jesus Christ and His redemption for the sins of humanity.

Muslims believe that salvation is attained through submission to the will of Allah, observance of the Five Pillars of Islam and the performance of good deeds.

Furthermore, Christianity contains the concept of original sin, inherent in human nature because of Adam and Eve, and which requires Baptism to be eradicated through the grace of Jesus.

For Islam, original sin does not exist and Adam and Eve were forgiven.

Religious practices reflect the theological differences between Christians and Muslims.

Muslims observe the Five Pillars of Islam: the profession of faith (Shahada), prayer (Salah), almsgiving (Zakat), fasting during the month of Ramadan (Sawm) and pilgrimage to Mecca (Hajj). These pillars represent the foundations of the Islamic faith and guide the daily lives of Muslims.

Christians, on the other hand, follow the Sacraments, which vary slightly among the different denominations. The principal Sacraments include Baptism, the Eucharist (Communion), Confession, Confirmation, Marriage, Anointing of the Sick and Holy Orders. These Sacraments are regarded as means of divine grace and are central to Christian religious practice.

Furthermore, in Christianity the veneration of Saints is accepted and encouraged, men and women who lived and died in the Grace of God, often killed for their faith and who became models of Christian life. One can turn to them for intercession before God.

In Islam, nothing and no one can be associated with Allah, therefore no one can be considered worthy of interceding between God and man. Likewise, Islam has always condemned the veneration of relics.

Despite the theological and practical differences, there are nevertheless many similarities between Islam and Christianity. Both religions recognise the importance of prophets and divine revelations. For example, Muslims and Christians venerate figures such as Abraham, as we have seen, but also Moses and Jesus, although with different roles and interpretations.

Both religions also emphasise the importance of prayer, charity and moral life.

The similarities between Islam and Christianity also include an apocalyptic view of the world. Both religions believe in the Day of Judgement, when God will judge humanity for its actions.

Furthermore, both Islam and Christianity promote mercy, justice and love for one’s neighbour as fundamental values.

The Qur’an and the Bible

The Qur’an and the Bible are the sacred texts of Islam and Christianity respectively. Although both are considered divine revelations, they present significant differences in terms of content, structure and interpretation.

The Qur’an, composed of 114 surahs or chapters, is considered by Muslims the literal word of God (kalimat Allāh), created before the origin of humanity and dictated by God to Adam, Abraham, and above all to the prophet Muhammad through the angel Gabriel. For this reason, the text of the Qur’an is always identical to itself, unchanged, nor can it be changed or translated from Arabic. This is because man forgets and distorts the message, so it must be reiterated. The Qur’an is written in Classical Arabic, with poetic and rhythmic language. It is considered a very eloquent text and has influenced Arabic literature. The text of the Qur’an is organised according to the length of the surahs, not in chronological order.

The Bible, on the other hand, is a collection of texts written by various authors over the course of centuries and comprises the Old and New Testaments. The Old Testament contains Jewish sacred texts, while the New Testament focuses on the life and teachings of Jesus Christ. The Bible has been written and translated into various languages (Hebrew, Ancient Greek, Aramaic), with different literary styles among the various books and authors.

One of the main differences between the Qur’an and the Bible concerns the figure of Jesus. In Christianity, Jesus is considered the Son of God and the Saviour of humanity, while in Islam he is recognised as one of the greatest prophets, but not as divine. This fundamental divergence has a profound influence on the doctrines and practices of the two religions.

For the Islamic religion, the Qur’an has supreme authority and its interpretation is regulated by religious scholars (ulema) and traditions of exegesis (tafsir). In Christianity, the Bible is considered divine authority, but its interpretation can vary among the different denominations and theological traditions.
