Consequently, such behavior can be attributed to naught save the petty-mindedness of such souls as tread the valley of arrogance and pride, are lost in the wilds of remoteness, walk in the ways of their idle fancy, and follow the dictates of the leaders of their faith. Their chief concern is mere opposition; their sole desire is to ignore the truth. Unto every discerning observer it is evident and manifest that had these people in the days of each of the Manifestations of the Sun of Truth sanctified their eyes, their ears, and their hearts from whatever they had seen, heard, and felt, they surely would not have been deprived of beholding the beauty of God, nor strayed far from the habitations of glory. But having weighed the testimony of God by the standard of their own knowledge, gleaned from the teachings of the leaders of their faith, and found it at variance with their limited understanding, they arose to perpetrate such unseemly acts.

Bahá’u’lláh, Gleanings from the Writings of Bahá’u’lláh, p. 18

If Thou wishest a discerning eye and seekest for a hearing ear, set thou aside that which thou hast heard from fathers and ancestors, for such things are imitation -- and then seek for the truth with the utmost attention until the divine confirmation may reach thee ant the matter may be properly disclosed unto thee.

Bahá’u’lláh, Bahá’í World Faith, p. 387

At most it is this: that some are ignorant; they must be educated in order that they may become intelligent. Some are immature as children; they must be aided and assisted in order that they may become mature. Some are sick and ailing; they must be healed. But the suffering patient must not be tested by false treatment. The child must not be warped and hindered in its development. The ignorant must not be restricted by censure and criticism. We must look for the real, true remedy.

‘Abdu’l-Bahá, The Promulgation of Universal Peace, p. 40.

It is incumbent upon you to strip yourselves of every old garment (i. e., old beliefs and past customs). It is incumbent upon you to be severed from this contemptible earthly world. It is incumbent upon you (to seek after) the Kingdom, in this great Day!

‘Abdu’l-Bahá, Tablets of ‘Abdu’l-Bahá v1, p. 144

The foundations of the divine religions are one. If we investigate these foundations, we discover much ground for agreement, but if we consider the imitations of forms and ancestral beliefs, we find points of disagreement and division; for these imitations differ, while the sources and foundations are one and the same. That is to say, the fundamentals are conducive to unity, but imitations are the cause of disunion and dismemberment. Whosoever is lacking in love for humanity or manifests hatred and bigotry toward any part of it violates the foundation and source of his own belief and is holding to forms and imitations.

‘Abdu’l-Bahá, The Promulgation of Universal Peace, p. 40

The third criterion or standard of proof is traditional or scriptural -- namely, that every statement or conclusion should be supported by traditions recorded in certain religious books. When we come to consider even the Holy Books -- the Books of God -- we are led to ask, "Who understands these books? By what authority of explanation may these Books be understood?" It must be the authority of human reason, and if reason or intellect finds itself incapable of explaining certain questions, or if the possessors of intellect contradict each other in the interpretation of traditions, how can such a criterion be relied upon for accurate conclusions?
