The need for the centralization of authority in the National Spiritual Assembly, and the concentration of power in the various local Assemblies, is made manifest when we reflect that the Cause of Bahá’u’lláh is still in its age of tender growth and in a stage of transition; when we remember that the full implications and the exact significance of the Master’s world-wide instructions, as laid down in His Will, are as yet not fully grasped, and the whole Movement has not sufficiently crystallized in the eyes of the world.
It is our primary task to keep the most vigilant eye on the manner and character of its growth, to combat effectively the forces of separation and of sectarian tendencies, lest the Spirit of the Cause be obscured, its unity be threatened, its Teachings suffer corruption; lest extreme orthodoxy on one hand, and irresponsible freedom on the other, cause it to deviate from that Straight Path which alone can lead it to success.
