The Bahá'í Faith is monotheistic, believing in one, all-powerful creator God. They share this belief in God's nature with Christians, Jews, and Muslims, although what each of these religions believes about the one and only God can be quite different. Bahá'ís emphasize that God is ultimately unknowable in his essence, but human knowledge of God can be had through God's Messengers or Manifestations.
Bahá'í doctrine emphasizes the unity of mankind, despite differences such as race and class or economic status, the unity of the world's religions, and the progressive revelation of God to humanity.
Bahá'ís believe that the founders of great religions (such as Abraham-Judaism, Jesus-Christianity, the Buddha-Buddhism, and Muhammad-Islam) were sent by the one and only God to reveal his attributes and will, in the terms that were appropriate for the time. Although the Bahai faith imports people and ideas from other world religions, it is important to know that adherents to those faiths don't traditionally share those same beliefs. For example, Judaism hasn't traditionally taught about Abraham what Bahai's believe about him and Christianity hasn't traditionaaly taught about Jesus what Bahai's believe about him.
