The ocean is one body of water but different parts of it have particular designation, Atlantic, Pacific, Mediterranean, Antarctic, etc. If we consider the names, there is differentiation, but the water, the ocean itself is one reality.
Likewise the divine religions of the holy Manifestations of God are in reality one though in name and nomenclature they differ. Man must be a lover of the light no matter from what day-spring it may appear. He must be a lover of the rose no matter in what soil it may be growing. He must be a seeker of the truth no matter from what source it come. (‘Abdu'l-Baha, ‘The Promulgation of Universal Peace: Talks Delivered by 'Abdu'l-Bahá during His Visit to the United States and Canada in 1912’)
