All Religions have come from the same, one Creator. Each Manifestation of God revealed a message relevant to humankind’s stage of development. The key theme of the message for today is Unity.

O ye children of men! The fundamental purpose animating the Faith of God and His Religion is to safeguard the interests and promote the unity of the human race, and to foster the spirit of love and fellowship amongst men…Whatsoever is raised on this foundation, the changes and chances of the world can never impair its strength, nor will the revolution of countless centuries undermine its structure.

— Bahá’u’lláh

“We are all the leaves of one tree, the drops of one ocean.” — Bahá’u’lláh

The conviction that we belong to one human family is at the heart of the Bahá’í Faith. The principle of the oneness of humankind is “the pivot round which all the teachings of Bahá’u’lláh revolve”.

Bahá’u’lláh compared the world of humanity to the human body. Within this organism, millions of cells, diverse in form and function, play their part in maintaining a healthy system. The principle that governs the functioning of the body is cooperation. Its various parts do not compete for resources; rather, each cell, from its inception, is linked to a continuous process of giving and receiving.

Acceptance of the oneness of humanity demands that prejudice—whether racial, religious, or gender-related—must be totally eliminated.

The independent investigation of reality. Not found in any sacred Book of the past, it abolishes the need for clergy and sets us free from imitation and blind adherence to unexamined, dogmatic beliefs. Baha’is believe that no soul should follow ancestral or traditional beliefs without first questioning and examining their own inner landscape. Instead, the first Baha’i principle gives each individual the right and the duty to investigate and decide what they believe on their own:

…every individual member of humankind is exhorted and commanded to set aside superstitious beliefs, traditions and blind imitation of ancestral forms in religion and investigate reality for himself. Inasmuch as the fundamental reality is one, all religions and nations of the world will become one through investigation of reality. – ‘Abdu’l-Bahá

The world of humanity is possessed of two wings — the male and the female. So long as these two wings are not equivalent in strength the bird will not fly. Until womankind reaches the same degree as man, until she enjoys the same arena of activity, extraordinary attainment for humanity will not be realized; humanity cannot wing its way to heights of real attainment.

Taken together, science and religion provide the fundamental organizing principles by which individualscommunities, and institutions function and evolve. When the material and spiritual dimensions of the life of a community are kept in mind and due attention is given to both scientific and spiritual knowledge, the tendency to reduce human progress to the consumption of goods, services and technological packages is avoided. Scientific knowledge, to take but one simple example, helps the members of a community to analyse the physical and social implications of a given technological proposal—say, its environmental impact—and spiritual insight gives rise to moral imperatives that uphold social harmony and that ensure technology serves the common good. Together, these two sources of knowledge are essential to the liberation of individuals and communities from the traps of ignorance and passivity. They are vital to the advancement of civilization.
