The Kitáb-i-Aqdas - The Most Holy Book
Index term: respect for parents, under Children
n92.
We have conditioned it . . . upon the permission of their parents
In a letter written on his behalf, Shoghi Effendi has commented on this provision of the law:

Bahá'u'lláh has clearly stated the consent of all living parents is required for a Bahá'í marriage. This applies whether the parents are Bahá'ís or non-Bahá'ís, 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.
q104.
 
In the Tablet to Abá Badí', this holy verse hath been revealed: "Verily, We have enjoined on every son to serve his father." Such is the decree which We have set forth in the Book.
q106.
 
He is God, exalted be He, the Lord of majesty and power! The Prophets and Chosen Ones have all been commissioned by the One True God, magnified be His glory, to nurture the trees of human existence with the living waters of uprightness and understanding, that there may appear from them that which God hath deposited within their inmost selves. As may be readily observed, each tree yieldeth a certain fruit, and a barren tree is but fit for fire. The purpose of these Educators, in all they said and taught, was to preserve man's exalted station. Well is it with him who in the Day of God hath laid fast hold upon His precepts and hath not deviated from His true and fundamental Law. The fruits that best befit the tree of human life are trustworthiness and godliness, truthfulness and sincerity; but greater than all, after recognition of the unity of God, praised and glorified be He, is regard for the rights that are due to one's parents. This teaching hath been mentioned in all the Books of God, and reaffirmed by the Most Exalted Pen. Consider that which the Merciful Lord hath revealed in the Qur'án, exalted are His words: "Worship ye God, join with Him no peer or likeness; and show forth kindliness and charity towards your parents . . ." Observe how loving-kindness to one's parents hath been linked to recognition of the one true God! Happy they who are endued with true wisdom and understanding, who see and perceive, who read and understand, and who observe that which God hath revealed in the Holy Books of old, and in this incomparable and wondrous Tablet.
