The Unity of God
In the Word of God there is still another unity—the oneness of the Manifestations of God, Abraham, Moses, Jesus Christ, Muḥammad, the Báb and Bahá’u’lláh. This is a unity divine, heavenly, radiant, merciful—the one reality appearing in its successive Manifestations.
The Unity of Humanity
World order can be founded only on an unshakable consciousness of the oneness of mankind, a spiritual truth which all the human sciences confirm. Anthropology, physiology, psychology, recognize only one human species, albeit infinitely varied in the secondary aspects of life. Recognition of this truth requires abandonment of prejudice—prejudice of every kind—race, class, color, creed, nation, sex, degree of material civilization, everything which enables people to consider themselves superior to others.
The Unity of Religion
An essential principle of Bahá’u’lláh’s teaching is that religion must be the cause of unity and love amongst men; that it is the supreme effulgence of Divinity, the stimulus of life, the source of honor and productive of eternal existence. Religion is not intended to arouse enmity and hatred nor to become the source of tyranny and injustice. Should it prove to be the cause of hostility, discord and the alienation of mankind, assuredly the absence of religion would be preferable.
