If we allow prejudice of any kind [“racial, religious, political, economic, national, tribal, class, cultural, and that which is based on differences of education or age”] to manifest itself in us, we shall be guilty before God of causing a setback to the progress and real growth of the Faith of Bahá'u'lláh. It is incumbent upon every believer to endeavour with a fierce determination to eliminate this defect from his thoughts and acts. It is the duty of the institutions of the Faith to inculcate this principle in the hearts of the friends through every means at their disposal including summer schools, conferences, institutes and study classes.
The fundamental purpose of the Faith of Bahá'u'lláh is the realization of the organic unity of the entire human race. Bearing this glorious destiny in mind, and with entire reliance on the promises of the Blessed Beauty, we should follow His exhortation:
“We love to see you at all times consorting in amity and concord within the paradise of My good-pleasure, and to inhale from your acts the fragrance of friendliness and unity, of loving-kindness and fellowship. ...” (Baha’u’llah, ‘Gleanings from the Writings of Baha’u’llah’) (The Universal House of Justice, ‘Messages 1963 to 1986)
