When Was Islam Founded vs Christianity vs Judaism: Origins Compared

Judaism is the oldest of the three Abrahamic faiths, with its origins traditionally dated to the covenant God made with Abraham around 2000 BCE and the giving of the Torah to Moses around 1300 BCE. Rabbinic Judaism — the form practiced today — took shape after the destruction of the Second Temple in 70 CE, shifting focus from Temple sacrifice to Torah study and prayer.

Jewish tradition doesn't frame its founding as a single moment but as an ongoing covenantal relationship between God and the Jewish people. The faith sees itself as the root from which both Christianity and Islam grew, though it doesn't recognize either as a continuation of its covenant Quran 6:159.

Historically, Judaism predates both Christianity and Islam by centuries, making it the foundational tradition in the Abrahamic family. Its scriptures — the Torah, Nevi'im, and Ketuvim — form the Hebrew Bible, which Christians call the Old Testament and Muslims reference as earlier revelation Quran 7:11.

Christianity emerged in the 1st century CE in Roman-occupied Judea. Most historians date its founding to the ministry of Jesus of Nazareth, roughly 27–30 CE, with John's baptismal movement serving as an immediate precursor Mark 11:30. After Jesus's crucifixion and the disciples' proclamation of his resurrection, the faith spread rapidly across the Roman Empire.

The earliest Christian communities formed around 30–33 CE, and the faith was formally distinct from Judaism by the late 1st century. The New Testament canon was largely settled by the 4th century CE, and Christianity became the official religion of the Roman Empire under Emperor Theodosius in 380 CE.

Christians believe Jesus fulfilled Jewish prophecy and inaugurated a new covenant, making Christianity both continuous with and distinct from Judaism. The healing miracles attributed to Jesus — unprecedented in scope — were seen as signs of divine authority John 9:32.

Islam was founded in 610 CE when the Prophet Muhammad received his first Quranic revelation in a cave near Mecca. The faith grew rapidly, and by Muhammad's death in 632 CE it had unified much of the Arabian Peninsula. The Quran opens with the Basmala — 'In the name of God, the Most Gracious, the Most Merciful' — establishing the tone of the entire revelation Quran 1:1.

Islam teaches that it isn't a new religion but the restoration of the original monotheism of Abraham, Adam, and all the prophets. The Quran explicitly states that God's knowledge underlies every revelation: 'Know that it has been sent down with the knowledge of Allah, and that there is no deity except Him' Quran 11:14.

Muslims view divisions within religion critically, and the Quran warns against those who fragment their faith into sects Quran 6:159. Islam sees itself as the final, complete, and uncorrupted form of God's message — a claim that puts it in direct theological tension with both Judaism and Christianity on the question of which revelation supersedes the others.
