According to Bahá'í teachings, religious history is seen as an evolving educational process for mankind, through God's messengers, which are termed Manifestations of God. Bahá'u'lláh is seen as the most recent, pivotal, but not final of these individuals. He claimed to be the expected redeemer and teacher prophesied in Judaism, Christianity, Islam, Hinduism, Buddhism, and other religions, and that his mission was to establish a firm basis for unity throughout the world, and inaugurate an age of peace and justice, which Bahá'ís expect will inevitably arise.
Shoghi Effendi, the appointed head of the religion from 1921 to 1957, wrote the following summary of what he considered to be the distinguishing principles of Bahá'u'lláh's teachings, which, he said, together with the laws and ordinances of the Kitáb-i-Aqdas constitute the bed-rock of the Bahá'í Faith:
The independent search after truth, unfettered by superstition or tradition; the oneness of the entire human race, the pivotal principle and fundamental doctrine of the Faith; the basic unity of all religions; the condemnation of all forms of prejudice, whether religious, racial, class or national; the harmony which must exist between religion and science; the equality of men and women, the two wings on which the bird of human kind is able to soar; the introduction of compulsory education; the adoption of a universal auxiliary language; the abolition of the extremes of wealth and poverty; the institution of a world tribunal for the adjudication of disputes between nations; the exaltation of work, performed in the spirit of service, to the rank of worship; the glorification of justice as the ruling principle in human society, and of religion as a bulwark for the protection of all peoples and nations; and the establishment of a permanent and universal peace as the supreme goal of all mankind—these stand out as the essential elements [which Bahá'u'lláh proclaimed].
