Bahá'u'lláh,
The Kitáb-i-Aqdas
“ One must guide mankind to the ocean of true understanding in a spirit of love and tolerance. The Kitáb-i-Aqdas itself beareth eloquent testimony to the loving providence of God. The principle governing this progressive application was enunciated in a letter written on behalf of Shoghi Effendi to a National Spiritual Assembly in 1935: The laws revealed by Bahá’u’lláh in the Aqdas are, whenever practicable and not in direct conflict with the Civil Law of the land, absolutely binding on every believer or Bahá’í institution whether in the East or in the West. ”
