The Oneness of God: There is only one God, though He may be called by many names. If God created us, then by definition He must be beyond our understanding.
The Oneness of Religion: God has sent His Messengers at different times and places in human history. They are the founders of the major faiths - Moses, Buddha, Krishna, Christ, Muhammad, Zoroaster. Bahá'ís believe there is only actually one religion, the religion of God, and each of these apparently separate faiths takes us a step further forward. Their spiritual teachings are the same in essence, but they build on the previous Message to take us ever higher.
