I was, moreover, opposed by mine own kindred, although, as Thou knowest, they were dear to me and I had desired for them that which I had desired for mine own self.

Bahá’u’lláh, Prayers and Meditations by Bahá’u’lláh, p. 107

If a man in his own home doth not treat his relations and friends with entire trustworthiness and integrity, his dealings with the outside world -- no matter how much trustworthiness and honesty he may bring to them -- will prove barren and unproductive. First one should order one's own domestic affairs, then attend to one's business with the public.

‘Abdu’l-Bahá, The Compilation of Compilations vol II, p. 339

If one of thy relations oppress thee, complain not against him before the magistrate; rather manifest magnificent patience during every calamity and hardship. Verily thy Master is the Lord of Faithfulness! Forgive and overlook the shortcomings which have appeared in that one, for the sake of love and affection.

‘Abdu’l-Bahá, Bahá’í World Faith, p. 374

It is highly important for man to raise a family. So long as he is young, because of youthful self-complacency, he does not realize its significance, but this will be a source of regret when he grows old.

‘Abdu’l-Bahá, Lights of Guidance, p. 219

Note ye how easily, where unity existeth in a given family, the affairs of that family are conducted; what progress the members of that family make, how they prosper in the world. Their concerns are in order, they enjoy comfort and tranquility, they are secure, their position is assured, they come to be envied by all.

‘Abdu’l-Bahá, Selections from the Writings of ‘Abdu’l-Bahá, p. 278

Both Bahá’u’lláh and the Báb emphasize the need of children in marriage. The latter, for example, states that to beget children is the highest physical fruit of man's existence. But neither say whether the number of children should be limited or not. Or if it is to be limited what is the proper method to be used.

Shoghi Effendi, Unrestrained as the Wind, p. 132

One of the most paramount needs of the Cause in ... is that the friends should unite, should become really keenly conscious of the fact that they are one spiritual family, held together by bonds more sacred and eternal than those physical ties which make people of the same family. If the friends will forget all personal differences and open their hearts to a great love for each other for the sake of Bahá’u’lláh, they will find that their powers are vastly increased; they will attract the heart of the public, and will witness a rapid growth of the Holy Faith in... The National Spiritual Assembly should do all in its power to foster unity among the believers, and to educate them in the Administration as this is the channel through which their community life must flow, and which, when properly understood and practised, will enable the work of the Cause to go ahead by leaps and bounds.

Shoghi Effendi, The Compilation of Compilations vol II, p. 11-12

Unless and until the believers really come to realize they are one spiritual family, knit together by a bond more lasting than mere physical ties can ever be, they will not be able to create that warm community atmosphere which alone can attract the hearts of humanity, frozen for lack of real love and feeling.

Shoghi Effendi, NSA USA - Developing Distinctive Bahá’í Communities

The friends should . . . draw closer to each other, knowing that they form one spiritual family, closer to each other, in the sight of God, than those united by ties of blood.

From a letter written on behalf of Shoghi Effendi, 8 May, 1948, Source Unknown

. . . countless ills . . . are the consequences of the disunity afflicting the human family.

The Universal House of Justice, Century of Light, p. 97

A couple who are physically incapable of having children may, of course, marry, since the procreation of children is not the only purpose of marriage. However, it would be contrary to the spirit of the Teachings for a couple to decide voluntarily never to have any children.

Universal House of Justice, Lights of Guidance, p. 379

The new child which will soon be given to you by God is, indeed, a divine blessing, of which you should feel proud, and of the manifold responsibilities and obligations which it necessarily entails you should become fully aware. It is now that you can truly say that you have a family life. Without a child there can be no family, and through him the bonds of love and of service can be truly and strongly maintained between the wife and husband.

Universal House of Justice to an individual believer, 5 June 1974
