Failure to meet the challenge of such submission has manifested itself with especially devastating consequences throughout the centuries in betrayal of the Messengers of God and of the ideals they taught. This discussion is not the place for a review of the nature and provisions of the specific Covenant by means of which Bahá’u’lláh has successfully preserved the unity of those who recognize Him and serve His purpose. It is sufficient to note the strength of the language He reserves for its deliberate violation by those who simultaneously pretend allegiance to it: “They that have turned away therefrom are reckoned among the inmates of the nethermost fire in the sight of thy Lord, the Almighty, the Unconstrained.” The reason for the severity of this condemnation is obvious. Few people have difficulty in recognizing the danger to social well-being of such familiar crimes as murder, rape or fraud, nor the need for society to take effective measures of self-protection. But how are Bahá’ís to think about a perversity which, if unchecked, would destroy the very means essential to the creation of unity—would, in the uncompromising words of the Master, “become even as an axe striking at the very root of the Blessed Tree”? The issue is not one of intellectual dissent, nor even of moral weakness. Many people are resistant to accepting authority of one kind or another, and eventually distance themselves from circumstances that require it. Persons who have been attracted to the Bahá’í Faith but who decide, for whatever reason, to leave it are entirely free to do so.
