Religion is verily the chief instrument for the establishment of order in the world and of tranquillity amongst its peoples ... The greater the decline of religion, the more grievous the waywardness of the ungodly. This cannot but lead in the end to chaos and confusion. 
(Bahá'u'lláh, Tablets of Bahá'u'lláh revealed after the Kitáb-i-Aqdas; The Compilation of Compilations, vol. III, Social and Economic Development)
