"Divine Revelation is orderly, continuous and progressive" makes it possible to view religion as one single civilizing force, which the Guardian underscores in the passage below:
"Just as the organic evolution of mankind has been slow and gradual, and involved successively the unification of the family, the tribe, the city-state, and the nation, so has the light vouchsafed by the Revelation of God, at various stages in the evolution of religion, and reflected in the successive Dispensations of the past, been slow and progressive. Indeed the measure of Divine Revelation, in every age, has been adapted to, and commensurate with, the degree of social progress achieved in that age by a constantly evolving humanity."
with the above in mind, let us reflect on the following words of Abdu'l-Baha:
"Religion is the light of the world, and the progress, achievement, and happiness of man result from obedience to the laws set down in the holy Books. Beifly, it is demonstrable that in this life, both outwardly and inwardly the mightiest of structures, the most solidly established, the most enduring, standing guard over the world, assuring both the spiritual and the material perfections of mankind, and protecting the happiness and the civilization of society - is religion" Abdu'l-Baha
