As it hath been shown that no one can enjoy the melodies of the divine nightingale save those who are custodians thereof, it is necessary and obligatory for every one to submit the difficulties of the divine questions and intricacies in the references of the Dawning-places of Holiness, to the possessors of brilliant hearts and the bearers of the mysteries of unity; so that the questions may be solved through the supreme confirmation and divine bounties, and not by the assistance of acquired sciences.
(Bahá’í Scriptures, p. 49)
To none is given the right to question their words or disparage their conduct, for they [the Prophets of God] are the only ones who can claim to have understood the patient and to have correctly diagnosed its ailments …
(Bahá’u’lláh, Gleanings from the Writings of Bahá’u’lláh, pp. 80-81)
We are glad that you have brought to our attention the questions perplexing some of the believers. It is much better for these questions to be put freely and openly than to have them, unexpressed, burdening the hearts of devoted believers.
(Universal House of Justice, The Compilation of Compilations vol. I, p. 343)
Whoso, while reading the Sacred Scriptures, is tempted to choose therefrom whatever may suit him with which to challenge the authority of the Representative of God among men, is, indeed, as one dead, though to outward seeming he may walk and converse with his neighbours, and share with them their food and their drink.
(Adib Taherzadeh, The Revelation of Bahá’u’lláh v 1, p. 29-33)
