The three major monotheistic religions - Judaism, Christianity, and Islam - originated in Southwest Asia and share some common beliefs but also have key differences. Judaism began with the Israelites and belief in God/Yahweh over 3,700 years ago. Christianity arose from Judaism through the teachings of Jesus Christ and his disciples. Islam was founded in the 7th century by the prophet Muhammad and is the youngest of the three faiths. All three religions believe in one supreme god and have important holy texts, but they differ in their prophets, holy days, and some religious practices and beliefs.
