The issue is not the past, but the implications for the present. Problems arise where followers of one of the world’s faiths prove unable to distinguish between its eternal and transitory features, and attempt to impose on society rules of behaviour that have long since accomplished their purpose. The principle is fundamental to an understanding of religion’s social role: “The remedy the world needeth in its present-day afflictions can never be the same as that which a subsequent age may require”, Bahá’u’lláh points out. “Be anxiously concerned with the needs of the age ye live in, and centre your deliberations on its exigencies and requirements.” [47]
