‘Abdu’l-Bahá emphasized the authority of the House of Justice. It would, He said, be under the protection of Bahá’u’lláh and inspired by the Holy Spirit.

The Most Holy Book is the Book to which all peoples shall refer, and in it the Laws of God have been revealed. Laws not mentioned in the Book should be referred to the decision of the Universal House of Justice. There will be no grounds for difference… Beware, beware lest anyone create a rift or stir up sedition. Should there be differences of opinion, the Supreme House of Justice would immediately resolve the problems. Whatever will be its decision, by majority vote, shall be the real truth, inasmuch as that House is under the protection, unerring guidance and care of the one true Lord. He shall guard it from error and will protect it under the wing of His sanctity and infallibility. He who opposes it is cast out and will eventually be of the defeated.

The Supreme House of Justice should be elected according to the system followed in the election of the parliaments of Europe. And when the countries would be guided, the Houses of Justice of the various countries would elect the Supreme House of Justice.

At whatever time all the beloved of God in each country appoint their delegates, and these in turn elect their representatives, and these representatives elect a body, that body shall be regarded as the Supreme House of Justice.

Those matters of major importance which constitute the foundation of the Law of God are explicitly recorded in the Text, but subsidiary laws are left to the House of Justice. The wisdom of this is that the times never remain the same, for change is a necessary quality and an essential attribute of this world, and of time and place. Therefore the House of Justice will take action accordingly.

Let it not be imagined that the House of Justice will take any decision according to its own concepts and opinions. God forbid! The Supreme House of Justice will take decisions and establish laws through the inspiration and confirmation of the Holy Spirit, because it is in the safekeeping and under the shelter and protection of the Ancient Beauty, and obedience to its decisions is a bounden and essential duty and an absolute obligation, and there is no escape for anyone.

Say, O people: Verily the Supreme House of Justice is under the wings of your Lord, the Compassionate, the All-Merciful, that is, under His protection, His care, and His shelter; for He has commanded the firm believers to obey that blessed, sanctified and all-subduing body, whose sovereignty is divinely ordained and of the Kingdom of Heaven and whose laws are inspired and spiritual.

Briefly, this is the wisdom of referring the laws of society to the House of Justice. In the religion of Islam, similarly, not every ordinance was explicitly revealed; nay not a tenth part of a tenth part was included in the Text; although all matters of major importance were specifically referred to, there were undoubtedly thousands of laws which were unspecified. These were devised by the divines of a later age according to the laws of Islamic jurisprudence, and individual divines made conflicting deductions from the original revealed ordinances. All these were enforced. Today this process of deduction is the right of the body of the House of Justice, and the deductions and conclusions of individual learned men have no authority, unless they are endorsed by the House of Justice. The difference is precisely this, that from the conclusions and endorsements of the body of the House of Justice whose members are elected by and known to the worldwide Bahá’í community, no differences will arise; whereas the conclusions of individual divines and scholars would definitely lead to differences, and result in schism, division, and dispersion. The oneness of the Word would be destroyed, the unity of the Faith would disappear, and the edifice of the Faith of God would be shaken.

The House of Justice, however, according to the explicit text of the Law of God, is confined to men; this for a wisdom of the Lord God’s, which will ere long be made manifest as clearly as the sun at high noon.

The sacred and youthful branch, the Guardian of the Cause of God, as well as the Universal House of Justice, to be universally elected and established, are both under the care and protection of the Abhá Beauty, under the shelter and unerring guidance of His Holiness, the Exalted One (may my life be offered up for them both). Whatsoever they decide is of God. Whoso obeyeth him not, neither obeyeth them, hath not obeyed God; whoso rebelleth against him and against them hath rebelled against God; whoso opposeth him hath opposed God; whoso contendeth with them hath contended with God; whoso disputeth with him hath disputed with God; whoso denieth him hath denied God; whoso disbelieveth in him hath disbelieved in God; whoso deviateth, separateth himself and turneth aside from him hath in truth deviated, separated himself and turned aside from God. May the wrath, the fierce indignation, the vengeance of God rest upon him! The mighty stronghold shall remain impregnable and safe through obedience to him who is the Guardian of the Cause of God. It is incumbent upon the members of the House of Justice, upon all the Aghsán, the Afnán, the Hands of the Cause of God to show their obedience, submissiveness and subordination unto the Guardian of the Cause of God, to turn unto him and be lowly before him.

And now, concerning the House of Justice which God hath ordained as the source of all good and freed from all error, it must be elected by universal suffrage, that is, by the believers. Its members must be manifestations of the fear of God and daysprings of knowledge and understanding, must be steadfast in God’s faith and the well-wishers of all mankind. By this House is meant the Universal House of Justice, that is, in all countries a secondary House of Justice must be instituted, and these secondary Houses of Justice must elect the members of the Universal one. Unto this body all things must be referred. It enacteth all ordinances and regulations that are not to be found in the explicit Holy Text. By this body all the difficult problems are to be resolved and the Guardian of the Cause of God is its sacred head and the distinguished member for life of that body. Should he not attend in person its deliberations, he must appoint one to represent him. Should any of the members commit a sin, injurious to the common weal, the Guardian of the Cause of God hath at his own discretion the right to expel him, whereupon the people must elect another one in his stead. This House of Justice enacteth the laws and the government enforceth them. The legislative body must reinforce the executive, the executive must aid and assist the legislative body so that through the close union and harmony of these two forces, the foundation of fairness and justice may become firm and strong, that all the regions of the world may become even as Paradise itself.

Unto the Most Holy Book every one must turn and all that is not expressly recorded therein must be referred to the Universal House of Justice. That which this body, whether unanimously or by a majority doth carry, that is verily the Truth and the Purpose of God Himself. Whoso doth deviate therefrom is verily of them that love discord, hath shown forth malice and turned away from the Lord of the Covenant. By this House is meant that Universal House of Justice which is to be elected from all countries, that is from those parts in the East and West where the loved ones are to be found, after the manner of the customary elections in Western countries such as those of England.

It is incumbent upon these members (of the Universal House of Justice) to gather in a certain place and deliberate upon all problems which have caused difference, questions that are obscure and matters that are not expressly recorded in the Book. Whatsoever they decide has the same effect as the Text itself. And inasmuch as this House of Justice hath power to enact laws that are not expressly recorded in the Book and bear upon daily transactions, so also it hath power to repeal the same. Thus for example, the House of Justice enacteth today a certain law and enforceth it, and a hundred years hence, circumstances having profoundly changed and the conditions having altered, another House of Justice will then have power, according to the exigencies of the time, to alter that law. This it can do because that law formeth no part of the Divine Explicit Text. The House of Justice is both the initiator and the abrogator of its own laws.
