Bahá’u’lláh… came and once
more renewed the foundation of Faith. He brought back the teachings of God, and
the humane practices of the time of Christ. He quenched the thirst of the
thirsty, He awakened the careless and called the attention of the heedless to
the Divine secrets. He declared the unity of humanity, and spread abroad the
teaching of the equality of all men.
- ‘Abdu'l-Baha (From a talk, ‘Abdu'l-Baha
in London, September 8, 1911’)
