That the divers communions of the earth, and the manifold
systems of religious belief, should never be allowed to foster the feelings of
animosity among men, is, in this Day, of the essence of the Faith of God and
His Religion. These principles and laws, these firmly-established and mighty
systems, have proceeded from one Source, and are the rays of one Light. That
they differ one from another is to be attributed to the varying requirements of
the ages in which they were promulgated.
- Baha'u'llah (Gleanings from the
Writings of Baha'u'llah)
