"Each one of the divine religions has established two kinds of ordinances: the essential and the accidental. The essential ordinances rest upon the firm, unchanging, eternal foundations of the Word itself. They concern spiritualities, seek to stabilize morals, awaken intuitive susceptibilities, reveal the knowledge of God and inculcate the love of all mankind. The accidental laws concern the administration of outer human actions and relations, establishing rules and regulations requisite for the world of bodies and their control. These are ever subject to change and supersedure according to exigencies of time, place and condition. For example, during the time of Moses, ten commandments concerning the punishment of murder were revealed in His Book. Divorce was sanctioned and polygamy allowable to a certain extent. If a man committed theft, his hand was cut off. This was drastic law and severe punishment applicable to the time of Moses. But when the time of Christ came, minds had developed, realizations were keener and spiritual perceptions had advanced so that certain laws concerning murder, plurality of wives and divorce were abrogated. But the essential ordinances of the Mosaic dispensation remained unchanged. These were the fundamental realities of the knowledge of God and the holy Manifestations, the purification of morals, the awakening of spiritual susceptibilities—eternal principles in which there is no change or transformation. Briefly, the foundation of the divine religions is one eternal foundation, but the laws for temporary conditions and exigencies are subject to change. Therefore, by adherence to these temporary laws, blindly following and imitating ancestral forms, difference and divergence have arisen among followers of the various religions, resulting in disunion, strife and hatred. Blind imitations and dogmatic observances are conducive to alienation and disagreement; they lead to bloodshed and destruction of the foundations of humanity. Therefore, the religionists of the world must lay aside these imitations and investigate the essential foundation or reality itself, which is not subject to change or transformation. This is the divine means of agreement and unification."
