All the peoples have a fundamental belief in common. Being one, truth cannot be divided, and the differences that appear to exist among the nations only result from their attachment to prejudice. If only men would search out truth, they would find themselves united. II.—The second principle of Bahá’u’lláh is: The Unity of Mankind The one all-loving God bestows His divine Grace and Favour on all mankind; one and all are servants of the Most High, and His Goodness, Mercy and loving Kindness are showered upon all His creatures. The glory of humanity is the heritage of each one. All men are the leaves and fruit of one same tree, they are all branches of the tree of Adam, they all have the same origin. The same rain has fallen upon them all, the same warm sun makes them grow, they are all refreshed by the same breeze. The only differences that exist and that keep them apart are these: there are the children who need guidance, the ignorant to be instructed, the sick to be tended and healed; thus, I say that the whole of humanity is enveloped by the Mercy and Grace of God. As the Holy Writings tell us: All men are equal before God. He is no respecter of persons. III.—The third principle of Bahá’u’lláh is: Religion should be the Cause of Love and Affection Religion should unite all hearts and cause wars and disputes to vanish from the face of the earth, give birth to spirituality, and bring life and light to each heart. If religion becomes a cause of dislike, hatred and division, it were better to be without it, and to withdraw from such a religion would be a truly religious act. For it is clear that the purpose of a remedy is to cure; but if the remedy should only aggravate the complaint it had better be left alone. Any religion which is not a cause of love and unity is no religion. All the holy prophets were as doctors to the soul; they gave prescriptions for the healing of mankind; thus any remedy that causes disease does not come from the great and supreme Physician. IV.—The fourth principle of Bahá’u’lláh is: The Unity of Religion and Science We may think of science as one wing and religion as the other; a bird needs two wings for flight, one alone would be useless. Any religion that contradicts science or that is opposed to it, is only ignorance—for ignorance is the opposite of knowledge. Religion which consists only of rites and ceremonies of prejudice is not the truth. Let us earnestly endeavour to be the means of uniting religion and science. ‘Alí, the son-in-law of Muḥammad, said: ‘That which is in conformity with science is also in conformity with religion’. Whatever the intelligence of man cannot understand, religion ought not to accept. Religion and science walk hand in hand, and any religion contrary to science is not the truth. V.—The fifth principle of Bahá’u’lláh is: Prejudices of Religion, Race or Sect destroy the foundation of Humanity
