Quotes from Bahá'í Scriptures on the Oneness of God

There is one God; mankind is one; the foundations of religion are one. Let us worship Him, and give praise for all His great Prophets and Messengers who have manifested His brightness and glory.

- Bahá'í Scriptures

God witnesseth that there is no God but Him, the Gracious, the Best-Beloved. All grace and bounty are His. To whomsoever He will He giveth whatsoever is His wish. He, verily, is the All-Powerful, the Almighty, the Help in Peril, the Self-Subsisting.

- Bahá'í Scriptures

Now is the moment in which to cleanse thyself with the waters of detachment that have flowed out from the Supreme Pen, and to ponder, wholly for the sake of God, those things which, time and again, have been sent down or manifested, and then to strive, as much as lieth in thee, to quench, through the power of wisdom and the force of thy utterance, the fire of enmity and hatred which smouldereth in the hearts of the peoples of the world. The Divine Messengers have been sent down, and their Books were revealed, for the purpose of promoting the knowledge of God, and of furthering unity and fellowship amongst men. But now behold, how they have made the Law of God a cause and pretext for perversity and hatred. How pitiful, how regrettable, that most men are cleaving fast to, and have busied themselves with, the things they possess, and are unaware of, and shut out as by a veil from, the things God possesseth!

- Bahá'í Scriptures

Inasmuch as our God is one God and the creator of all mankind, He provides for and protects all. We acknowledge him as a God of kindness, justice and mercy. Why then should we, His children and followers, war and fight, bringing sorrow and grief into the hearts of each other? God is loving and merciful. His intention in religion has ever been the bond of unity and affinity between humankind.
