From the Writings of Shoghi Effendi
Let us also bear in mind that the keynote of the Cause of God is not dictatorial authority, but humble fellowship, not arbitrary power, but the spirit of frank and loving consultation. Nothing short of the spirit of a true Bahá’í can hope to reconcile the principles of mercy and justice, of freedom and submission, of the sanctity of the right of the individual and of self-surrender, of vigilance, discretion and prudence on the one hand and fellowship, candour and courage on the other.
(23 February 1924 to the Bahá’ís of America, published in “Bahá’í Administration”, pp. 63-64) 
The duties of those whom the friends have freely and conscientiously elected as their representatives are no less vital and binding than the obligations of those who have chosen them. Their function is not to dictate, but to consult, and consult not only among themselves, but as much as possible with the friends whom they represent. They must regard themselves in no other light but that of chosen instruments for a more efficient and dignified presentation of the Cause of God. They should never be led to suppose that they are the central ornaments of the body of the Cause, intrinsically superior to others in capacity or merit, and sole promoters of its teachings and principles. They should approach their task with extreme humility, and endeavour by their open-mindedness, their high sense of justice and duty, their candour, their modesty, their entire devotion to the welfare and interests of the friends, the Cause, and humanity, to win not only the confidence and the genuine support and respect of those whom they should serve, but also their esteem and real affection. They must at all times avoid the spirit of exclusiveness, the atmosphere of secrecy, free themselves from a domineering attitude, and banish all forms of prejudice and passion from their deliberations. They should, within the limits of wise discretion, take the friends into their confidence, acquaint them with their plans, share with them their problems and anxieties, and seek their advice and counsel. And when they are called upon to arrive at a certain decision, they should, after dispassionate, anxious, and cordial consultation, turn to God in prayer, and with earnestness and conviction and courage record their vote and abide by the voice of the majority, which we are told by our Master to be the voice of truth, never to be challenged, and always to be whole-heartedly enforced. To this voice the friends must heartily respond, and regard it as the only means that can ensure the protection and advancement of the Cause.

Not infrequently, nay oftentimes, the most lowly, untutored, and inexperienced among the friends will, by the sheer inspiring force of selfless and ardent devotion, contribute a distinct and memorable share to a highly involved discussion in any given assembly....

Indeed it has ever been the cherished desire of our Master ‘Abdu’l-Bahá that the friends in their councils, local as well as national, should by their candour, their honesty of purpose, their singleness of mind, and the thoroughness of their discussions achieve unanimity in all things....
