Religion

And yet, is not the object of every Revelation to effect a transformation in the whole character of mankind, a transformation that shall manifest itself both outwardly and inwardly, that shall affect both its inner life and external conditions? For if the character of mankind be not changed, the futility of God's universal Manifestations would be apparent.

Bahá’u’lláh, The Kitab-i-Iqan, p. 240-241

The essence of religion is to testify unto that which the Lord hath revealed, and follow that which He hath ordained in His mighty Book.

Bahá’u’lláh, Tablets of Bahá’u’lláh, p. 155

The weakening of the pillars of religion hath strengthened the hands of the ignorant and made them bold and arrogant. Verily I say, whatsoever hath lowered the lofty station of religion hath increased the waywardness of the wicked, and the result cannot be but anarchy.

Bahá’u’lláh, quoted in The World Order of Bahá’u’lláh by Shoghi Effendi, p.186

Alas! that humanity is completely submerged in imitations and unrealities notwithstanding the truth of divine religion has ever remained the same. Superstitions have obscured the fundamental reality, the world is darkened and the light of religion is not apparent. This darkness is conducive to differences and dissensions; rites and dogmas are many and various; therefore discord has arisen among the religious systems whereas religion is for the unification of mankind. True religion is the source of love and agreement amongst men, the cause of the development of praiseworthy qualities; but the people are holding to the counterfeit and imitation, negligent of the reality which unifies; so they are bereft and deprived of the radiance of religion. They follow superstitions inherited from their fathers and ancestors. To such an extent has this prevailed that they have taken away the heavenly light of divine truth and sit in the darkness of imitations and imaginations. That which was meant to be conducive to life has become the cause of death; that which should have been an evidence of knowledge is now a proof of ignorance; that which was a factor in the sublimity of human nature has proved to be its degradation. Therefore the realm of the religionist has gradually narrowed and darkened and the sphere of the materialist has widened and advanced; for the religionist has held to imitation and counterfeit, neglecting and discarding holiness and the sacred reality of religion. When the sun sets it is the time for bats to fly. They come forth because they are creatures of the night. When the lights of religion become darkened the materialists appear. They are the bats of night. The decline of religion is their time of activity; they seek the shadows when the world is darkened and clouds have spread over it.

‘Abdu’l-Bahá, Foundations of World Unity, p. 71

And among the teachings of Bahá’u’lláh is that religion must be in conformity with science and reason, so that it may influence the hearts of men. The foundation must be solid and must not consist of imitations.

‘Abdu’l-Bahá, Selections from the Writings of ‘Abdu’l-Bahá, p. 299

Bahá’u’lláh says that religion must be conducive to love and unity. If it proves to be the source of hatred and enmity, its absence is preferable; for the will and law of God is love, and love is the bond between human hearts. Religion is the light of the world. If it is made the cause of darkness through human misunderstanding and ignorance, it would be better to do without it.
