Some of the basic principles of the Bahá’í Faith are the following:
Oneness of Humanity
Bahá’u'lláh taught the Oneness of humanity; that is to say, all the children of men are under the mercy of the Great God. They are the sons of one God; they are trained by God. He has placed the crown of humanity on the head of every one of the servants of God. Therefore all nations and peoples must consider themselves brethren. They are all descendants from Adam. They are the branches, leaves, flowers and fruits of One Tree. They are pearls from one shell.
(Abdu’l-Baha, Abdu’l-Baha in London, p. 28)
Elimination of Prejudice
Bahá’u'lláh has also taught that prejudices, whether religious, racial, patriotic or political are destructive to the foundations of human development. Prejudices of any kind are the destroyers of human happiness and welfare. Until they are dispelled the advancement of the world of humanity is not possible, yet racial, religious and national bias are observed everywhere. For thousands of years the world of humanity has been agitated and disturbed by prejudices. As long as it prevails, warfare, animosity and hatred will continue. Therefore if we seek to establish peace we must cast aside this obstacle, for otherwise agreement and composure are not to be attained.
(Abdu’l-Baha, Baha’i World Faith - Abdu’l-Baha Section, p. 240)
Personal Investigation of the Truth
God has given man the eye of investigation by which he may see and recognize truth. He has endowed man with ears that he may hear the message of reality and conferred upon him the gift of reason by which he may discover things for himself. This is his endowment and equipment for the investigation of reality. Man is not intended to see through the eyes of another, hear through another’s ears nor comprehend with another’s brain. Each human creature has individual endowment, power and responsibility in the creative plan of God. Therefore depend upon your own reason and judgment and adhere to the outcome of your own investigation…
(Abdu’l-Baha, Foundations of World Unity, p. 75)
Love and Service to Mankind
Be ye loving fathers to the orphan, and a refuge to the helpless, and a treasury for the poor, and a cure for the ailing. Be ye the helpers of every victim of oppression, the patrons of the disadvantaged. Think ye at all times of rendering some service to every member of the human race. Pay ye no heed to aversion and rejection, to disdain, hostility, injustice: act ye in the opposite way. Be ye sincerely kind, not in appearance only. Let each one of God’s loved ones centre his attention on this: to be the Lord’s mercy to man; to be the Lord’s grace. Let him do some good to every person whose path he crosseth, and be of some benefit to him. Let him improve the character of each and all, and reorient the minds of men. In this way, the light of divine guidance will shine forth, and the blessings of God will cradle all mankind…
(Abdu’l-Baha, Selections from the Writings of Abdu’l-Baha, p. 3)
The Oneness of Religions: Progressive Revelation
It is clear and evident to thee that all the Prophets are the Temples of the Cause of God, Who have appeared clothed in divers attire. If thou wilt observe with discriminating eyes, thou wilt behold Them all abiding in the same tabernacle, soaring in the same heaven, seated upon the same throne, uttering the same speech, and proclaiming the same Faith. Such is the unity of those Essences of Being, those Luminaries of infinite and immeasurable splendor! Wherefore, should one of these Manifestations of Holiness proclaim saying: “I am the return of all the Prophets,” He, verily, speaketh the truth. In like manner, in every subsequent Revelation, the return of the former Revelation is a fact, the truth of which is firmly established….
(Baha’u'llah, Gleanings from the Writings of Baha’u'llah, p. 51)
Harmony between Religion, Science, and Reason
Among other principles of Bahá’u'lláh’s teachings was the harmony of science and religion. Religion must stand the analysis of reason. It must agree with scientific fact and proof so that science will sanction religion and religion fortify science. Both are indissolubly welded and joined in reality. If statements and teachings of religion are found to be unreasonable and contrary to science, they are outcomes of superstition and imagination.
(Abdu’l-Baha, The Promulgation of Universal Peace, p. 175)
International Auxiliary Language
Bahá’u'lláh has proclaimed the adoption of a universal language. A language shall be agreed upon by which unity will be established in the world. Each person will require training in two languages: his native tongue and the universal auxiliary form of speech. This will facilitate intercommunication and dispel the misunderstandings which the barriers of language have occasioned in the world. All people worship the same God and are alike His servants. When they are able to communicate freely, they will associate in friendship and concord, entertain the greatest love and fellowship for each other, and in reality the Orient and Occident will embrace in unity and agreement. (Abdu’l-Baha, The Promulgation of Universal Peace, p. 300)
Bahá’u'lláh has announced that inasmuch as ignorance and lack of education are barriers of separation among mankind, all must receive training and instruction. Through this provision the lack of mutual understanding will be remedied and the unity of mankind furthered and advanced. Universal education is a universal law.
(Abdu’l-Baha, The Promulgation of Universal Peace, p. 300)
Equality of Men and Women
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. When the two wings or parts become equivalent in strength, enjoying the same prerogatives, the flight of man will be exceedingly lofty and extraordinary. Therefore, woman must receive the same education as man and all inequality be adjusted. Thus, imbued with the same virtues as man, rising through all the degrees of human attainment, women will become the peers of men, and until this equality is established, true progress and attainment for the human race will not be facilitated.
(Abdu’l-Baha, The Promulgation of Universal Peace, p. 374)
The Abolition of the Extremes of Wealth and Poverty
Sixth, Bahá’u'lláh set forth principles of guidance and teaching for economic readjustment. Regulations were revealed by Him which ensure the welfare of the commonwealth. As the rich man enjoys his life surrounded by ease and luxuries, so the poor man must, likewise, have a home and be provided with sustenance and comforts commensurate with his needs. This readjustment of the social economy is of the greatest importance inasmuch as it ensures the stability of the world of humanity; and until it is effected, happiness and prosperity are impossible.
(Abdu’l-Baha, The Promulgation of Universal Peace, p. 181)
The gift of God to this enlightened age is the knowledge of the oneness of mankind and of the fundamental oneness of religion. War shall cease between nations, and by the will of God the Most Great Peace shall come; the world will be seen as a new world, and all men will live as brothers.
(Abdu’l-Baha, Abdu’l-Baha in London, p. 19)
