Diversity of languages has been a fruitful cause of discord. The function of language is to convey the thought and purpose of one to another. Therefore, it matters not what language man speaks or employs. Sixty years ago Bahá’u’lláh advocated one language as the greatest means of unity and the basis of international conference. He wrote to the kings and rulers of the various nations, recommending that one language should be sanctioned and adopted by all governments. According to this each nation should acquire the universal language in addition to its native tongue. The world would then be in close communication, consultation would become general, and dissensions due to diversity of speech would be removed. Another teaching of Bahá’u’lláh is in relation to universal peace: that all mankind must be awakened to and become conscious of the harm of war, that they should be brought to realize the benefits of peace and know that peace is from God while warfare is satanic. Man must emulate the merciful God and turn away from satanic promptings in order that universal inclination shall be toward peace, love and unity and the discord of war vanish. Lack of equality between man and woman is, likewise, a cause of human dissension. Bahá’u’lláh has named this as an important factor of discord and separation, for so long as humankind remains unequally divided in right and importance between male and female, no unity can be established. In a perfect human body it is not possible for one organ to be complete and another defective. In the great body of human society it is impossible to establish unity and coordination if one part is considered perfect and the other imperfect. When the perfect functions of both parts are in operation, harmony will prevail. God has created man and woman equal as to faculties. He has made no distinction between them. Woman has not reached the level of man in human accomplishment because of the lack of opportunity and education. If educational opportunities were made equal and similar, the two parts, man and woman, would equalize in attainment. God has intended no difference between them that should be productive of discord. He has endowed all with human faculties, and all are manifestations of His mercy. If we say man and woman differ in creational endowment, it is contrary to divine justice and intention. Both are human. If God has created one perfect and the other defective, He is unjust. But God is just; all are perfect in His intention and creative endowment. To assume imperfection in the creature is to presuppose imperfection in the almighty Creator. The soul that excels in attainment of His attributes and graces is most acceptable before God.
