Universal Religion

The people of religions find, in the teaching of His Holiness Bahá’u’lláh, the establishment of Universal Religion—a religion that perfectly conforms with present conditions, which in reality effects the immediate cure of the incurable disease, which relieves every pain, and bestows the infallible antidote for every deadly poison.
For if we wish to arrange and organize the world of mankind in accordance with the present religious imitations and thereby to establish the felicity of the world of mankind, it is impossible and impracticable—for example, the enforcement of the laws of the Old Testament (Torah) and also of the other religions in accordance with present imitations.
But the essential basis of all the Divine Religions which pertains to the virtues of the world of mankind and is the foundation of the welfare of the world of man, is found in the teachings of His Holiness Bahá’u’lláh in the most perfect presentation.
Similarly, with regard to the peoples who clamor for freedom: the moderate freedom which guarantees the welfare of the world of mankind and maintains and preserves the universal relationships, is found in its fullest power and extension in the teachings of His Holiness Bahá’u’lláh.
