For if God, glorified be His Name, should today speak a word that all people have spoken heretofore and shall speak hereafter, that word would still be new, were ye to reflect upon it. Consider the term “Divine Unity”, which the Manifestations of God have uttered in every Dispensation, a goodly term which all the divers peoples and kindreds of the world have spoken. Nevertheless, in each Dispensation, it hath been made new and hath in no wise been divested of its novel character. Into every word that God doth speak a new spirit is breathed, and the breezes of life are wafted therefrom upon all things both outwardly and inwardly.

—Bahá’u’lláh
