k3.
O ye peoples of the world! Know assuredly that My commandments are the lamps of My loving providence among My servants, and the keys of My mercy for My creatures. Thus hath it been sent down from the heaven of the Will of your Lord, the Lord of Revelation. Were any man to taste the sweetness of the words which the lips of the All-Merciful have willed to utter, he would, though the treasures of the earth be in his possession, renounce them one and all, that he might vindicate the truth of even one of His commandments, shining above the Dayspring of His bountiful care and loving-kindness.
k29.
Say: This is that hidden knowledge which shall never change, since its beginning is with nine, the symbol that betokeneth the concealed and manifest, the inviolable and unapproachably exalted Name. As for what We have appropriated to the children, this is a bounty conferred on them by God, that they may render thanks unto their Lord, the Compassionate, the Merciful. These, verily, are the Laws of God; transgress them not at the prompting of your base and selfish desires. Observe ye the injunctions laid upon you by Him Who is the Dawning-place of Utterance. The sincere among His servants will regard the precepts set forth by God as the Water of Life to the followers of every faith, and the Lamp of wisdom and loving providence to all the denizens of earth and heaven.
k99.
Say: O leaders of religion! Weigh not the Book of God with such standards and sciences as are current amongst you, for the Book itself is the unerring Balance established amongst men. In this most perfect Balance whatsoever the peoples and kindreds of the earth possess must be weighed, while the measure of its weight should be tested according to its own standard, did ye but know it.
k186.
This is a Book which hath become the Lamp of the Eternal unto the world, and His straight, undeviating Path amidst the peoples of the earth. Say: This is the Dayspring of Divine knowledge, if ye be of them that understand, and the Dawning-place of God's commandments, if ye be of those who comprehend.

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.
