The Law of Marriage:
And when He [God] desired to manifest grace and beneficence to men, and to set the world in order, He revealed observances and created laws; among them He established the law of marriage, made it as a fortress for well-being and salvation, and enjoined it upon us in that which was sent down out of the heaven of sanctity in His Most Holy Book. He saith, great is His glory: “Marry, O people, that from you may appear he who will remember Me amongst My servants; this is one of My commandments unto you; obey it as an assistance to yourselves.”
(Baha’u’llah: Baha’i Prayers (US), p. 105)

The pledge of marriage, the verse to be spoken individually by the bride and the bridegroom in the presence of at least two witnesses acceptable to the Spiritual Assembly is, as stipulated in the Kitab-i-Aqdas (The Most Holy Book):
“We will all, verily, abide by the Will of God.”
(`Abdu’l-Baha: Baha’i Prayers (US edition), p. 104)

Baha’u’llah has clearly stated the consent of all living parents is required for a Baha’i marriage. This applies whether the parents are Baha’is or non-Baha’is, divorced for years or not. This great law He has laid down to strengthen the social fabric, to knit closer the ties of the home, to place a certain gratitude and respect in the hearts of the children for those who have given them life and sent their souls out on the eternal journey towards their Creator.
(Shoghi Effendi, quoted by the Universal House of Justice: Aqdas: Notes, p. 207)

Characteristics of Baha’i Marriage:
Baha’i marriage is the commitment of the two parties one to the other, and their mutual attachment of mind and heart. Each must, however, exercise the utmost care to become thoroughly acquainted with the character of the other, that the binding covenant between them may be a tie that will endure forever. Their purpose must be this: to become loving companions and comrades and at one with each other for time and eternity….
The true marriage of Baha’is is this, that husband and wife should be united both physically and spiritually, that they may ever improve the spiritual life of each other, and may enjoy everlasting unity throughout all the worlds of God. This is Baha’i marriage.
(`Abdu’l-Baha: Selections … `Abdu’l-Baha, p. 118)

The Lord, peerless is He, hath made woman and man to abide with each other in the closest companionship, and to be even as a single soul. They are two helpmates, two intimate friends, who should be concerned about the welfare of each other.
If they live thus, they will pass through this world with perfect contentment, bliss, and peace of heart, and become the object of divine grace and favour in the Kingdom of heaven.
(`Abdu’l-Baha: Selections … `Abdu’l-Baha, p. 122)

In this glorious Cause the life of a married couple should resemble the life of the angels in heaven – a life full of joy and spiritual delight, a life of unity and concord, a friendship both mental and physical. The home should be orderly and well-organized. Their ideas and thoughts should be like the rays of the sun of truth and the radiance of the brilliant stars in the heavens. Even as two birds they should warble melodies upon the branches of the tree of fellowship and harmony. They should always be elated with joy and gladness and be a source of happiness to the hearts of others. They should set an example to their fellow-men, manifest true and sincere love towards each other and educate their children in such a manner as to blazon the fame and glory of their family.
(`Abdu’l-Baha: Lights of Guidance, pp. 220-221)

Marriage, among the mass of the people, is a physical bond, and this union can only be temporary, since it is foredoomed to a physical separation at the close.
Among the people of Baha, however, marriage must be a union of the body and of the spirit as well, for here both husband and wife are aglow with the same wine, both are enamoured of the same matchless Face, both live and move through the same spirit, both are illumined by the same glory. This connection between them is a spiritual one, hence it is a bond that will abide forever. Likewise do they enjoy strong and lasting ties in the physical world as well, for if the marriage is based both on the spirit and the body, that union is a true one, hence it will endure. If, however, the bond is physical and nothing more, it is sure to be only temporary, and must inexorably end in separation.
When, therefore, the people of Baha undertake to marry, the union must be a true relationship, a spiritual coming together as well as a physical one, so that throughout every phase of life, and in all the worlds of God, their union will endure; for this real oneness is a gleaming out of the love of God.
(`Abdu’l-Baha: Selections … `Abdu’l-Baha, p. 117)

The institution of marriage, as established by Baha’u’llah, while giving due importance to the physical aspect of marital union, considers it as subordinate to the moral and spiritual purposes and functions with which it has been invested by an all-wise and loving Providence. Only when these different values are given each their due importance, and only on the basis of the subordination of the physical to the moral, and the carnal to the spiritual can such excesses and laxity in marital relations as our decadent age is so sadly witnessing be avoided, and family life be restored to its original purity, and fulfil the true function for which it has been instituted by God.
(Shoghi Effendi: Family Life, pp. 401-402)

Baha’u’llah has urged marriage upon all people as the natural and rightful way of life. He has also, however, placed strong emphasis on its spiritual nature, which, while in no way precluding a normal physical life, is the most essential aspect of marriage. That two people should live their lives in love and harmony is of far greater importance than that they should be consumed with passion for each other. The one is a great rock of strength on which to lean in time of need; the other a purely temporary thing which may at any time die out.
(Shoghi Effendi: Family Life, pp. 404-405)

Family Life:
The parents must exert every effort to rear their offspring to be religious, for should the children not attain this greatest of adornments, they will not obey their parents, which in a certain sense means that they will not obey God.
(Baha’u’llah: Family Life, p. 385)

According to the teachings of Baha’u’llah the family, being a human unit, must be educated according to the rules of sanctity. All the virtues must be taught the family. The integrity of the family bond must be constantly considered, and the rights of the individual members must not be transgressed. The rights of the son, the father, the mother – none of them must be transgressed, none of them must be arbitrary. Just as the son has certain obligations to his father, the father, likewise, has certain obligations to his son. The mother, the sister and other members of the household have their certain prerogatives. All these rights and prerogatives must be conserved, yet the unity of the family must be sustained. The injury of one shall be considered the injury of all; the comfort of each, the comfort of all; the honor of one, the honor of all.
(`Abdu’l-Baha: Promulgation of Universal Peace, p. 168)

As to thy question concerning the husband and wife, the tie between them and the children given to them by God: Know thou, verily, the husband is one who hath sincerely turned unto God, is awakened by the call of the Beauty of El-Baha and chanteth the verses of Oneness in the great assemblies; the wife is a being who wisheth to be overflowing with and seeketh after the attributes of God and His names; and the tie between them is none other than the Word of God. Verily, it [the Word of God] causeth the multitudes to assemble together and the remote ones to be united. Thus the husband and wife are brought into affinity, are united and harmonized, even as though they were one person. Through their mutual union, companionship and love great results are produced in the world, both material and spiritual. The spiritual result is the appearance of divine bounties. The material result is the children who are born in the cradle of the love of God, who are nurtured by the breast of the knowledge of God, who are brought up in the bosom of the gift of God, and who are fostered in the lap of the training of God. Such children are those of whom it was said by Christ, “Verily, they are the children of the Kingdom!”
(`Abdu’l-Baha: Family Life, pp. 390-391)

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 tranquillity, they are secure, their position is assured, they come to be envied by all. Such a family but addeth to its stature and its lasting honour, as day succeedeth day.
(`Abdu’l-Baha: Selections … `Abdu’l-Baha, p. 279)

The father must always endeavour to educate his son and to acquaint him with the heavenly teachings. He must give him advice and exhort him at all times, teach him praiseworthy conduct and character, enable him to receive training at school and to be instructed in such arts and sciences as are deemed useful and necessary. In brief, let him instil into his mind the virtues and perfections of the world of humanity. Above all he should continually call to his mind the remembrance of God so that his throbbing veins and arteries may pulsate with the love of God.
The son, on the other hand, must show forth the utmost obedience towards his father, and should conduct himself as a humble and a lowly servant. Day and night he should seek diligently to ensure the comfort and welfare of his loving father and to secure his good pleasure. He must forgo his own rest and enjoyment and constantly strive to bring gladness to the hearts of his father and mother, that thereby he may attain the good pleasure of the Almighty and be graciously aided by the hosts of the unseen.
(`Abdu’l-Baha: Family Life, pp. 393-394)

Of a surety, there is no greater pride and glory for a woman than to be a handmaid in God’s Court of Grandeur; and the qualities that shall merit her this station are an alert and wakeful heart; a firm conviction of the unity of God, the Peerless; a heartfelt love for all His maidservants; spotless purity and chastity; obedience to and consideration for her husband; attention to the education and nurturing of her children; composure, calmness, dignity and self-possession; diligence in praising God, and worshipping Him both night and day; constancy and firmness in His holy Covenant; and the utmost ardour, enthusiasm, and attachment to His Cause….
(`Abdu’l-Baha: Family Life, p. 393)

O ye loving mothers, know ye that in God’s sight, the best of all ways to worship Him is to educate the children and train them in all the perfections of humankind; and no nobler deed than this can be imagined.
(`Abdu’l-Baha: Selections … `Abdu’l-Baha, p. 139)

In this Most Great Dispensation Thou dost accept the intercession of children in behalf of their parents. This is one of the special infinite bestowals of this Dispensation.
(`Abdu’l-Baha: Baha’i Prayers (US edition), p. 65)

My home is the home of peace. My home is the home of joy and delight. My home is the home of laughter and exultation. Whosoever enters through the portals of this home, must go out with gladsome heart. This is the home of light; whosoever enters here must become illumined….
(`Abdu’l-Baha: Family Life, p. 397)

Divorce:
Regarding the Baha’i teachings on divorce. While the latter has been made permissible by Baha’u’llah yet he has strongly discouraged its practice, for if not checked and seriously controlled it leads gradually to the disruption of family life and to the disintegration of society….
(Shoghi Effendi: Divorce, pp. 238-239)

Wherever there is a Baha’i family, those concerned should by all means do all they can to preserve it, because divorce is strongly condemned in the Teachings, whereas harmony, unity and love are held up as the highest ideals in human relationships.
(Shoghi Effendi: Family Life, pp. 410-411)
