Some of the principles of the Bahá'í Faith are listed below. Bahá'u'lláh wrote volumes of scriptures throughout His lifetime, detailing these principles and many more.
Humanity is one. People of all races, nations, economic groups and religious backgrounds are equal in the sight of God. Bahá'u'lláh says, "Ye are all leaves of one tree and the fruits of one branch." By this it is meant that the world of humanity is like a tree, the nations or peoples are the different limbs or branches of that tree and the individual human creatures are as the fruits and blossoms thereof.
Bahá'ís perceive the role of religion in society as being an attracting force that unites and bind hearts together. The Bahá'í Faith is here to unite all the peoples of the world, regardless of their differences. For this reason, many of the activities Bahá'ís are engaged in promote a unifying attitude amongst all members of society.
The principle of the oneness of religion does not mean that the various religious creeds and organizations are the same. Rather, Bahá'u'lláh teaches that there is only one religion and all of the Messengers of God have progressively revealed its nature. Together, the world's great religions are expressions of a single unfolding Divine plan, "the changeless Faith of God, eternal in the past, eternal in the future."
Since all the religions come from the same source - the same God - the core teachings of all religions are infact one. The social teachings however, differ according to the needs of society at that time. Religion provides the remedy for social ills. Since society progresses, religion must also progress.
Bahá'u'lláh emphasizes the fundamental obligation of human beings to acquire knowledge with their "own eyes and not through the eyes of others." One of the main sources of conflict in the world today is the fact that many people blindly and uncritically follow various traditions, movements, and opinions. God has given each human being a mind and the capacity to differentiate truth from falsehood. If individuals fail to use their reasoning capacities and choose instead to accept without question certain opinions and ideas, either out of admiration for or fear of those who hold them, then they are neglecting their basic moral responsibility as human beings.
The Bahá'í Faith does not have clergy or priests. Instead it is the moral obligation of every individual to independently investigate religious and spiritual truths.
Harmony between science and religion as two complementary systems of knowledge that must work together to advance the well-being and progress of humanity. Science without religion is materialism - religion without science is superstition.
Full equality between women and men in all departments of life and at every level of society.
In the words of `Abdu'l-Bahá, the son of Bahá'u'lláh
"... inasmuch as ignorance and lack of education are barriers of separation among mankind, all must receive training and instruction. Trough this provision the lack of mutual understanding will be remedied and the unity of mankind furthered and advanced. Universal education is a universal law. It is therefore incumbent upon every father to teach and instruct his children according to his possibilities. If he is unable to educate them, the body politic, the representative of the people, must provide the means for their education."
