Every person is essentially a spiritual being with unique talents and capacities, "a mine rich in gems of inestimable value."

Acceptance of the oneness of humanity demands that prejudice—whether racial, religious, or gender-related—must be totally eliminated.

Misconceptions and prejudices that consider one group of people as superior to another are a major contributor to humanity’s present afflictions. 

Prejudice is a false perception, or preconception, of others based on ignorance, blinding us to the fact that every person is essentially a spiritual being with unique talents and capacities, Bahá’u’lláh affirms a “mine rich in gems of inestimable value.”

What Bahá’ís Believe - Elimination of Prejudice

What's required to cast away the fallacious doctinre of racial superiorty?

Pathway to the Shrine of the Báb

 "A tremendous effort is required by both races if their outlook, their manners, and conduct are to reflect, in this darkened age, the spirit and teachings of the Faith of Bahá’u’lláh. Casting away once and for all the fallacious doctrine of racial superiority, with all its attendant evils, confusion, and miseries, and welcoming and encouraging the intermixture of races, and tearing down the barriers that now divide them, they should each endeavor, day and night, to fulfill their particular responsibilities in the common task which so urgently faces them."

"... Let the white make a supreme effort in their resolve to contribute their share to the solution of this problem, to abandon once for all their usually inherent and at times subconscious sense of superiority, to correct their tendency towards revealing a patronizing attitude towards the members of the other race, to persuade them through their intimate, spontaneous and informal association with them of the genuineness of their friendship and the sincerity of their intentions, and to master their impatience of any lack of responsiveness on the part of a people who have received, for so long a period, such grievous and slow-healing wounds. Let the Negroes, through a corresponding effort on their part, show by every means in their power the warmth of their response, their readiness to forget the past, and their ability to wipe out every trace of suspicion that may still linger in their hearts and minds." 

"Let neither think that the solution of so vast a problem is a matter that exclusively concerns the other. Let neither think that such a problem can either easily or immediately be resolved. Let neither think that they can wait confidently for the solution of this problem until the initiative has been taken, and the favorable circumstances created, by agencies that stand outside the orbit of their Faith."

"Let neither think that anything short of genuine love, extreme patience, true humility, consummate tact, sound initiative, mature wisdom, and deliberate, persistent, and prayerful effort, can succeed in blotting out the stain which this patent evil has left on the fair name of their common country."

Racial prejudice is the most vital and challenging issue confronting the [American] Bahá’í community at the present stage of its evolution.

Pathway descending from The Universal House of Justice

 "As to racial prejudice, the corrosion of which, for well-nigh a century, has bitten into the fiber, and attacked the whole social structure of American society, it should be regarded as constituting the most vital and challenging issue confronting the Bahá’í community at the present stage of its evolution. The ceaseless exertions which this issue of paramount importance calls for, the sacrifices it must impose, the care and vigilance it demands, the moral courage and fortitude it requires, the tact and sympathy it necessitates, invest this problem, which the American believers are still far from having satisfactorily resolved, with an urgency and importance that cannot be overestimated. White and Negro, high and low, young and old, whether newly converted to the Faith or not, all who stand identified with it must participate in, and lend their assistance, each according to his or her capacity, experience, and opportunities, to the common task of fulfilling the instructions, realizing the hopes, and following the example, of ‘Abdu’l-Bahá. Whether colored or noncolored, neither race has the right, or can conscientiously claim, to be regarded as absolved from such an obligation, as having realized such hopes, or having faithfully followed such an example. A long and thorny road, beset with pitfalls, still remains untraveled, both by the white and the Negro exponents of the redeeming Faith of Bahá’u’lláh. On the distance they cover, and the manner in which they travel that road, must depend, to an extent which few among them can imagine, the operation of those intangible influences which are indispensable to the spiritual triumph of the American believers and the material success of their newly launched enterprise."
