The Covenant in the Bahá’í Faith creates and maintains a unified religious community.
“Whenever My laws appear like the sun in the heaven of Mine utterance, they must be faithfully obeyed by all, though My decree be such as to cause the heaven of every religion to be cleft asunder. He doth what He pleaseth. He chooseth; and none may question His choice. Whatsoever He, the Well-Beloved, ordaineth, the same is, verily, beloved.”
Bahá’u’lláh, The Kitáb-i-Aqdas, paragraph 7.
“Man often lacks the understanding to fathom the wisdom of some of the ordinances which are not to his liking. It therefore becomes a matter of demonstration of the depth of his faith when he is faced with a divine command the wisdom and rationale of which he cannot at that time understand.”
Letter from the Universal House of Justice, dated March 3, 1987, Fire & Gold, p. 195.
“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. Once one grasps certain basic principles of the Revelation of Bahá’u’lláh such uncertainties are easily dispelled. This is not to say that the Cause of God contains no mysteries. Mysteries there are indeed, but they are not of a kind to shake one’s faith once the essential tenets of the Cause and the indisputable facts of any situation are clearly understood.”
The Universal House of Justice, 9 March 1965, paragraph 1 / The Guardianship and the Universal House of Justice, p. 2.
“Obedience to the Laws of Bahá’u’lláh will necessarily impose hardships in individual cases. No one should expect, upon becoming a Bahá’í, that faith will not be tested, and to our finite understanding of such matters these tests may occasionally seem unbearable. But we are aware of the assurance which Bahá’u’lláh Himself has given the believers that they will never be called upon to meet a test greater than their capacity to endure.”
The Universal House of Justice, Lights of Guidance, p. 341.
“In considering the effect of obedience to the laws on individual lives, one must remember that the purpose of this life is to prepare the soul for the next. Here one must learn to control and direct one’s animal impulses, not to be a slave to them. Life in this world is a succession of tests and achievements, of falling short and of making new spiritual advances. Sometimes the course may seem very hard, but one can witness, again and again, that the soul who steadfastly obeys the law of Bahá’u’lláh, however hard it may seem, grows spiritually, while the one who compromises with the law for the sake of his own apparent happiness is seen to have been following a chimera: he does not attain the happiness he sought, he retards his spiritual advance and often brings new problems upon himself”
From a letter dated 6 February 1973 written by the Universal House of Justice to all National Spiritual Assemblies, published in “Messages from the Universal House of Justice 1968–1973” (Wilmette: Bahá’í Publishing Trust, 1976), p. 106, cited in the compilation “A Chaste and Holy Life,” extract 51.
“There are numerous individuals who share the ideals of the Faith and draw inspiration from its Teachings, while disagreeing with certain of its features, but those who actually enter the Bahá’í community have accepted, by their own free will, to follow the Teachings in their entirety, understanding that, if doubts and disagreements arise in the process of translating the Teachings into practice, the final arbiter is, by the explicit authority of the Revealed Text, the Universal House of Justice.”
The Universal House of Justice, letter of 2 July 1996, cited in the compilation “Issues Related to the Study of the Bahá’í Faith”, extract 7 in a letter from the Universal House of Justice dated 7 April 1999.
“It is not surprising that individual Bahá’ís hold and express different and sometimes defective understandings of the Teachings; this is but an evidence of the magnitude of the change that this Revelation is to effect in human consciousness. As believers with various insights into the Teachings converse — with patience, tolerance and open and unbiased minds — a deepening of comprehension should take place. The strident insistence on individual views, however, can lead to contention, which is detrimental not only to the spirit of Bahá’í association and collaboration but to the search for truth itself. Beyond contention, moreover, is the condition in which a person is so immovably attached to one erroneous viewpoint that his insistence upon it amounts to an effort to change the essential character of the Faith. This kind of behaviour, if permitted to continue unchecked, could produce disruption in the Bahá’í community, giving birth to countless sects as it has done in previous Dispensations. The Covenant of Bahá’u’lláh prevents this. The Faith defines elements of a code of conduct, and it is ultimately the responsibility of the Universal House of Justice, in watching over the security of the Cause and upholding the integrity of its Teachings, to require the friends to adhere to standards thus defined.”

“… by upholding Bahá’í law in the face of all difficulties we not only strengthen our own characters but influence those around us.”
From a letter dated 6 February 1973 written by the Universal House of Justice to all National Spiritual Assemblies cited in the compilation “A Chaste and Holy Life” excerpt 42.
“… when we accept the Manifestation of God for our time, we must accept what He says though at the moment we may not comprehend the meaning of some of His statements. Some things, such as Bahá’u’lláh’s Teachings regarding life after death, we have to accept on faith.”
