In the Bahá’í Cause, the principles of world administration were expressed by Bahá’u’lláh, and these principles were developed in the writings of ‘Abdu’l-Bahá, more especially in His Will and Testament.

The purpose of this organization is to make possible a true and lasting unity among peoples of different races, classes, interests, characters, and inherited creeds. A close and sympathetic study of this aspect of the Bahá’í Cause will show that the purpose and method of Bahá’í administration is so perfectly adapted to the fundamental spirit of the Revelation that it bears to it the same relationship as body to soul. In character, the principles of Bahá’í administration represent the science of cooperation; in application, they provide for a new and higher type of morality worldwide in scope....

A Bahá’í community differs from other voluntary gatherings in that its foundation is so deeply laid and broadly extended that it can include any sincere soul. Whereas other associations are exclusive, in effect if not in intention, and from method if not from ideal, Bahá’í association is inclusive, shutting the gates of fellowship to no sincere soul. In every gathering there is latent or developed some basis of selection. In religion this basis is a creed limited by the historical nature of its origin; in politics this is party or platform; in economics this is a mutual misfortune or mutual power; in the arts and sciences this basis consists of special training or activity or interest. In all these matters, the more exclusive the basis of selection, the stronger the movement—a condition diametrically opposed to that existing in the Bahá’í Cause. Hence the Cause, for all its spirit of growth and progress, develops slowly as regards the numbers of its active adherents. For people are accustomed to exclusiveness and division in all affairs. The important sanctions have ever been warrants and justifications of division. To enter the Bahá’í Movement is to leave these sanctions behind—an experience which at first invariably exposes one to new trials and sufferings, as the human ego revolts against the supreme sanction of universal love. The scientific must associate with the simple and unlearned, the rich with the poor, the white with the colored, the mystic with the literalist, the Christian with the Jew, the Muslim with the Parsee: and on terms removing the advantage of long established presumptions and privileges.

But for this difficult experience there are glorious compensations. Let us remember that art grows sterile as it turns away from the common humanity, that philosophy likewise loses its vision when developed in solitude, and that politics and religion never succeed apart from the general needs of mankind. Human nature is not yet known, for we have all lived in a state of mental, moral, emotional or social defense, and the psychology of defense is the psychology of inhibition. But the love of God removes fear; the removal of fear establishes the latent power, and association with others in spiritual love brings these powers into vital, positive expression. A Bahá’í community is a gathering where this process can take place in this age, slowly at first, as the new impetus gathers force, more rapidly as the members become conscious of the powers unfolding the flower of unity among men....

The responsibility for and supervision of local Bahá’í affairs is vested in a body known as the Spiritual Assembly. This body (limited to nine members) is elected annually on April 21st, the first day of Ridván (the Festival commemorating the Declaration of Bahá’u’lláh) by the adult declared believers of the community, the voting list being drawn up by the outgoing Spiritual Assembly. Concerning the character and functions of this body, ‘Abdu’l-Bahá has written as follows:—

It is incumbent upon every one [every believer] not to take any step [of Bahá’í activity] without consulting the Spiritual Assembly, and they must assuredly obey with heart and soul its bidding and be submissive unto it, that things may be properly ordered and well arranged. Otherwise every person will act independently and after his own judgment, will follow his own desire, and do harm to the Cause.

The prime requisites for them that take counsel together are purity of motive, radiance of spirit, detachment from all else save God, attraction to His Divine Fragrances, humility and lowliness amongst His loved ones, patience and long-suffering in difficulties and servitude to His exalted Threshold. Should they be graciously aided to acquire these attributes, victory from the unseen Kingdom of Bahá shall be vouchsafed to them. In this day, assemblies of consultation are of the greatest importance and a vital necessity. Obedience unto them is essential and obligatory. The members thereof must take counsel together in such wise that no occasion for ill-feeling or discord may arise. This can be attained when every member expresseth with absolute freedom his own opinion and must on no account feel hurt for not until matters are fully discussed can the right way be revealed. The shining spark of truth cometh forth only after the clash of differing opinions. If after discussion, a decision be carried unanimously well and good; but if, the Lord forbid, differences of opinion should arise, a majority of voices must prevail....

The first condition is absolute love and harmony amongst the members of the assembly. They must be wholly free from estrangement and must manifest in themselves the Unity of God, for they are the waves of one sea, the drops of one river, the stars of one heaven, the rays of one sun, the trees of one orchard, the flowers of one garden. Should harmony of thought and absolute unity be non-existent, that gathering shall be dispersed and that assembly be brought to naught. The second condition:—They must when coming together turn their faces to the Kingdom on High and ask aid from the Realm of Glory.... Discussions must all be confined to spiritual matters that pertain to the training of souls, the instruction of children, the relief of the poor, the help of the feeble throughout all classes in the world, kindness to all peoples, the diffusion of the fragrances of God and the exaltation of His Holy Word. Should they endeavor to fulfill these conditions the Grace of the Holy Spirit shall be vouchsafed unto them, and that assembly shall become the center of the Divine blessings, the hosts of Divine confirmation shall come to their aid, and they shall day by day receive a new effusion of Spirit.

Expounding this subject, Shoghi Effendi writes:—

... nothing whatever should be given to the public by any individual among the friends, unless fully considered and approved by the Spiritual Assembly in his locality; and if this (as is undoubtedly the case) is a matter that pertains to the general interest of the Cause in that land, then it is incumbent upon the Spiritual Assembly to submit it to the consideration and approval of the national body representing all the various local assemblies. Not only with regard to publication, but all matters without any exception whatsoever, regarding the interests of the Cause in that locality, individually or collectively, should be referred exclusively to the Spiritual Assembly in that locality, which shall decide upon it, unless it be a matter of national interest, in which case it shall be referred to the national [Bahá’í] body. With this national body also will rest the decision whether a given question is of local or national interest. (By national affairs is not meant matters that are political in their character, for the friends of God the world over are strictly forbidden to meddle with political affairs in any way whatsoever, but rather things that affect the spiritual activities of the body of the friends in that land.)
