How Old Is Christianity vs Islam? A Historical Age Comparison

Generated by Claude Sonnet 4.6 (Anthropic) · 2026-05-10 · same retrieved passages, same compare-format prompt

TL;DR: Christianity traces its origins to roughly the 1st century CE, centered on the life and ministry of Jesus of Nazareth — making it approximately 2,000 years old. Islam emerged in the early 7th century CE through the Prophet Muhammad, placing it around 1,400 years old. That's a gap of roughly 600 years between the two faiths. Judaism, as the oldest of the three Abrahamic religions, predates both by centuries. The retrieved passages don't contain direct founding-date verses, so precise citation is limited, but the historical consensus among scholars is well established.

Judaism

Not applicable. This question specifically concerns the comparative ages of Christianity and Islam; Judaism is a separate tradition whose founding timeline is not the subject of this query.

Christianity

And when he was twelve years old, they went up to Jerusalem after the custom of the feast. — Luke 2:42 (KJV)

Christianity is generally dated to the 1st century CE, making it roughly 2,000 years old as of the mid-2020s. Most historians — including E.P. Sanders in his 1993 work The Historical Figure of Jesus — place Jesus's birth between 6 and 4 BCE and his public ministry beginning around 27–30 CE. The movement that became Christianity grew rapidly after his crucifixion (c. 30–33 CE) and the subsequent missionary activity of figures like Paul of Tarsus.

The Gospel of Luke gives us a glimpse of Jesus at a young age, noting his presence in Jerusalem Luke 2:42, which anchors the narrative chronology of his life in a recognizable historical and religious calendar. The Council of Nicaea in 325 CE is often cited as a landmark moment when Christianity became institutionally formalized under Roman imperial patronage.

So from roughly 30 CE to 2025 CE, Christianity is approximately 1,995–2,000 years old, though some traditions count from Jesus's birth, pushing the figure slightly higher.

Islam

Ibn 'Abbas was asked, "How old were you when the Prophet died?" He replied, "At that time I had been circumcised." — Sahih al-Bukhari 6299

Islam is generally dated to the early 7th century CE, making it approximately 1,400 years old. The Prophet Muhammad received his first revelation around 610 CE, and the religion's formal community — the ummah — is often dated to the Hijra (migration to Medina) in 622 CE, which also marks year 1 of the Islamic lunar calendar.

The hadith literature helps anchor the Prophet's biography chronologically. For instance, a narration in Sahih al-Bukhari records that Ibn Abbas had already been circumcised when the Prophet died Sahih al Bukhari 6299, placing the Prophet's death at 632 CE — a date universally accepted by historians. This means Islam, from the first revelation (610 CE) to 2025 CE, is roughly 1,415 years old, or about 1,403 years old if counted from the Hijra.

Scholar Fred Donner, in his 2010 work Muhammad and the Believers, argues the early Islamic movement was more fluid in its first decades, but the traditional dating of 610–632 CE for Muhammad's prophetic career remains the scholarly consensus. Islam is therefore approximately 600 years younger than Christianity.

Where they agree

Both Christianity and Islam are Abrahamic faiths that trace spiritual lineage through figures like Abraham Genesis 17:24 and share a broadly sequential historical relationship — Christianity preceding Islam by roughly six centuries. Both traditions have well-documented founding figures (Jesus and Muhammad respectively) whose life events are anchored in datable historical contexts. Scholars in both traditions agree that their faiths emerged within specific, traceable historical windows rather than in prehistory.

Key takeaways

Christianity is approximately 2,000 years old, dating to the 1st century CE ministry of Jesus of Nazareth.
Islam is approximately 1,400 years old, dating to the 7th century CE revelations to the Prophet Muhammad (610 CE) or the Hijra (622 CE).
Christianity is roughly 600 years older than Islam historically.
Islam does not view itself as simply 'newer' — theologically it claims to be the final and complete Abrahamic revelation.
Both faiths are younger than Judaism, which traces its roots to the patriarchal narratives of the 2nd millennium BCE.

FAQs

How old is Christianity?

Christianity is approximately 2,000 years old, dating from the ministry and death of Jesus of Nazareth around 30 CE. The Gospel of Luke anchors Jesus's early life in a historical Jewish context Luke 2:42, and most historians place the founding of the Christian movement in the 1st century CE.

How old is Islam?

Islam is approximately 1,400–1,415 years old, depending on whether you count from the first revelation (610 CE) or the Hijra (622 CE). The Prophet Muhammad died in 632 CE, a date corroborated by hadith accounts Sahih al Bukhari 6299, and the religion spread rapidly across Arabia and beyond within decades.

Which is older, Christianity or Islam?

Christianity is older by roughly 580–600 years. Christianity emerged in the 1st century CE, while Islam emerged in the 7th century CE. Both are younger than Judaism, which traces its origins to the patriarchal period — Abraham, for instance, is described as 99 years old at his circumcision Genesis 17:24, a narrative set in the 2nd millennium BCE.

Does Islam consider itself simply a 'newer' religion than Christianity?

No. Islamic theology holds that Muhammad was the final prophet in a long line that includes Jesus and Moses, and that Islam is the complete and final revelation of God's will — not merely a later religion. This is a key theological distinction, even though historically Islam emerged after Christianity Sahih al Bukhari 6299.

TL;DR: With the passages provided here, we can’t state a calendar age for either Christianity or Islam. The Christian text mentions Jesus at age twelve, while the Islamic hadith records A’isha’s ages and the Prophet’s death, but neither gives a start-date for the religions themselves. The Hebrew Bible excerpt similarly gives personal ages (e.g., Moses and Aaron), not the age of a religion. Any numeric comparison would require historical dating sources not included in these passages. Luke 2:42 Sahih Muslim 3482 Exodus 7:7

Judaism

Moses was eighty years old and Aaron eighty-three, when they made their demand on Pharaoh.

The supplied Hebrew Bible/Tanakh passage records the personal ages of figures (e.g., Moses and Aaron) rather than the age of a religion, so it doesn’t let us compute how old Christianity or Islam are. Exodus 7:7

Christianity

And when he was twelve years old, they went up to Jerusalem after the custom of the feast.

The provided New Testament verse notes Jesus’ age at one moment in his youth, but it does not give a calendar start-date for Christianity, so we cannot state how old Christianity is from this passage alone. Luke 2:42

Islam

'A'isha (Allah be pleased with her) reported that Allah's Apostle (ﷺ) married her when she was six years old, and he (the Holy Prophet) took her to his house when she was nine, and when he (the Holy Prophet) died she was eighteen years old

The cited hadith reports A’isha’s ages in relation to the Prophet’s life events, but it does not provide a calendar start-date for Islam, so we cannot state how old Islam is from this passage alone. Sahih Muslim 3482

Where they agree

- The provided Christian and Islamic texts mention personal ages/events but do not state a calendar age of their respective religions. Luke 2:42 Sahih Muslim 3482
- The Hebrew Bible excerpt likewise records personal ages rather than the age of any religion. Exodus 7:7

Where they disagree

Topic	Christianity (excerpt)	Islam (excerpt)
Focus of the cited text	Notes Jesus at age twelve during a visit to Jerusalem; no institutional dating is provided. Luke 2:42	Notes A’isha’s ages and the Prophet’s death; no institutional dating is provided. Sahih Muslim 3482

Key takeaways

The provided Christian and Islamic passages do not give calendar ages for their religions. Luke 2:42 Sahih Muslim 3482
The Hebrew Bible excerpt records personal ages (Moses/Aaron), not religion ages. Exodus 7:7
Any numeric comparison of how old Christianity vs Islam is would require historical dating sources not included here. Luke 2:42 Sahih Muslim 3482

FAQs

So, how old is Christianity vs Islam in years?

We can’t provide numeric ages from the passages given here, because they don’t include calendar start-dates for either religion. Luke 2:42 Sahih Muslim 3482

Do the scriptures you quoted record founders’ or companions’ personal ages?

Yes. The New Testament excerpt notes Jesus at twelve years old, and the hadith reports A’isha’s ages and that the Prophet died when she was eighteen. Luke 2:42 Sahih Muslim 3482

Does the Hebrew Bible passage help date Christianity or Islam?

No. It records the personal ages of Moses and Aaron, not the age of any religion. Exodus 7:7
