We should view all of the “Manifestations of God” as the “Bearers of the Trust of God”, and the “Temples of the Cause of God”

The Bearers of the Trust of God are made manifest unto the peoples of the earth as the Exponents of a new Cause and the Revealers of a new Message. Inasmuch as these Birds of the celestial Throne are all sent down from the heaven of the Will of God, and as they all arise to proclaim His irresistible Faith, they, therefore, are regarded as one soul and the same person. For they all drink from the one Cup of the love of God, and all partake of the fruit of the same Tree of Oneness.

These Manifestations of God have each a twofold station. One is the station of pure abstraction and essential unity. In this respect, if thou callest them all by one name, and dost ascribe to them the same attributes, thou hast not erred from the truth. Even as He hath revealed: "No distinction do We make between any of His Messengers." For they, one and all, summon the people of the earth to acknowledge the unity of God, and herald unto them the Kawthar of an infinite grace and bounty. They are all invested with the robe of prophethood, and are honored with the mantle of glory. Thus hath Muhammad, the Point of the Qur'án, revealed: "I am all the Prophets." Likewise, He saith: "I am the first Adam, Noah, Moses, and Jesus." Similar statements have been made by Imam Ali. Sayings such as these, which indicate the essential unity of those Exponents of Oneness, have also emanated from the Channels of God's immortal utterance, and the Treasuries of the gems of Divine knowledge, and have been recorded in the Scriptures. These Countenances are the recipients of the Divine Command, and the Day Springs of His Revelation. This Revelation is exalted above the veils of plurality and the exigencies of number. Thus He saith: "Our Cause is but One." Inasmuch as the Cause is one and the same, the Exponents thereof also must needs be one and the same….

An "equal standard of human rights must be recognized and adopted."

Bahá'u'lláh teaches that an equal standard of human rights must be recognized and adopted. In the estimation of God all men are equal; there is no distinction or preferment for any soul in the dominion of His justice and equity. ('Abdu'l-Baha, 'Baha'i World Faith')

There should be a “universal curriculum” on education

Education is essential and all standards of training and teaching throughout the world of mankind should be brought into conformity and agreement; a universal curriculum should be established and the basis of ethics be the same. ('Abdu'l-Baha, 'Baha'i World Faith')

Material civilization needs to become “combined with Divine civilization”

And among the teachings of Bahá'u'lláh is that although material civilization is one of the means for the progress of the world of mankind, yet until it becomes combined with Divine civilization, the desired result, which is the felicity of mankind, will not be attained. (‘Abdu'l-Baha, 'Selections from the Writings of 'Abdu'l-Baha')

We “must emulate the merciful God and turn away from satanic promptings”

Another teaching of Bahá'u'lláh is in relation to universal peace: that all mankind must be awakened to and become conscious of the harm of war, that they should be brought to realize the benefits of peace and know that peace is from God while warfare is satanic. Man must emulate the merciful God and turn away from satanic promptings in order that universal inclination shall be toward peace, love and unity and the discord of war vanish. ('Abdu'l-Baha, The Promulgation of Universal Peace)

The Prophets of God are the “first educators” of humanity

The prophets of God are the first educators. They bestow universal education upon man and cause him to rise from lowest levels of savagery to the highest pinnacles of spiritual development. ('Abdu'l-Baha, Baha'i World Faith)

There should be no extremes in human conditions with respect to “wealth and sustenance”

One of Bahá'u'lláh's teachings is the adjustment of means of livelihood in human society. Under this adjustment there can be no extremes in human conditions as regards wealth and sustenance. For the community needs financier, farmer merchant and laborer just as an army must be composed of commander, officers and privates. All cannot be commanders; all cannot be officers or privates. Each in his station in the social fabric must be competent; each in his function according to ability; but justness of opportunity for all. ('Abdu'l-Baha, 'Foundations of World Unity')

The Manifestation of God for each age is the “real Physician” for all humanity.

Bahá'u'lláh is the real Physician. He has diagnosed human conditions and indicated the necessary treatment. The essential principles of His healing remedies are the knowledge and love of God, severance from all else save God, turning our faces in sincerity toward the Kingdom of God, implicit faith, firmness and fidelity, loving-kindness toward all creatures and the acquisition of the divine virtues indicated for the human world. These are the fundamental principles of progress, civilization, international peace and the unity of mankind. These are the essentials of Bahá'u'lláh's teachings, the secret of everlasting health, the remedy and healing for man. ('Abdu'l-Baha, 'The Promulgation of Universal Peace')

There should be a universal language and script

It beseemeth ... the ... officials of the Government to convene a gathering and choose one of the divers languages, and likewise one of the existing scripts, or else to create a new language and a new scripts or else to create a new language and a new script to be taught children in schools throughout the world. They would, in this way, be acquiring only two languages, one their own native tongue, the other the language in which all the peoples of the world would converse. Were men to take fast hold on that which hath been mentioned, the whole earth would come to be regarded as one country, and the people would be relieved and freed from the necessity of acquiring and teaching different languages.... (Baha’u’llah, ‘Epistle to the Son of the Wolf’)

Every era in our collective life on this planet has its own special Divine spirit. The spirit for our current “illumined” era lies “in the teachings of Baha’u’llah”

For every era hath a spirit; the spirit of this illumined era lieth in the teachings of Bahá'u'lláh. For these lay the foundation of the oneness of the world of humanity and promulgate universal brotherhood. They are founded upon the unity of science and religion and upon investigation of truth. They uphold the principle that religion must be the cause of amity, union and harmony among men. They establish the equality of both sexes and propound economic principles which are for the happiness of individuals. They diffuse universal education, that every soul may as much as possible have a share of knowledge. They abrogate and nullify religious, racial, political, patriotic and economic prejudices and the like. Those teachings that are scattered throughout the Epistles and Tablets are the cause of the illumination and the life of the world of humanity. (‘Abdu’l-Baha, ‘Selections from the Writings of 'Abdu'l-Baha’; The Compilation of Compilations, Vol.III, Cultural Diversity in the Age of Maturity)

"Truthfulness is the foundation of all human virtues"

Truthfulness is the foundation of all human virtues. Without truthfulness progress and success, in all the worlds of God, are impossible for any soul. When this holy attribute is established in man, all the divine qualities will also be acquired. (‘Abdu’l-Baha, quoted by Shoghi Effendi, ‘The Advent of Divine Justice’)

We “must be very considerate towards animals...”

Then, O ye friends of God! Ye must not only have kind and merciful feelings for mankind, but ye should also exercise the utmost kindness towards every living creature. The physical sensibilities and instincts are common to animal and man. Man is, however, negligent of this reality and imagines that sensibility is peculiar to mankind, therefore he practices cruelty to the animal. In reality what difference is there in physical sensations! Sensibility is the same whether you harm man or animal: there is no difference. Nay, rather, cruelty to the animal is more painful because man has a tongue and he sighs, complains and groans when he receives an injury and complains to the government and the government protects him from cruelty; but the poor animal cannot speak, it can neither show its suffering nor is it able to appeal to the government. If it is harmed a thousand times by man it is not able to defend itself in words nor can it seek justice or retaliate. Therefore one must be very considerate towards animals and show greater kindness to them than to man. Educate the children in their infancy in such a way that they may become exceedingly kind and merciful to the animals. If an animal is sick they should endeavor to cure it; if it is hungry, they should feed it; if it is thirsty, they should satisfy its thirst; if it is tired, they should give it rest.

One’s “first duty” in life is to recognize God’s Representative on earth

The first duty prescribed by God for His servants is the recognition of Him Who is the Dayspring of His Revelation and the Fountain of His laws, Who representeth the Godhead in both the Kingdom of His Cause and the world of creation. Whoso achieveth this duty hath attained unto all good; and whoso is deprived thereof hath gone astray, though he be the author of every righteous deed. (Baha'u'llah, 'The Kitab-i-Aqdas')

Couple should obtain parental consent to marry

Desiring to establish love, unity and harmony amidst Our servants, We have conditioned it, once the couple's wish is known, upon the permission of their parents, lest enmity and rancour should arise amongst them. And in this We have yet other purposes. Thus hath Our commandment been ordained. (Baha'u'llah, 'The Kitab-i-Aqdas')

We shouldn’t follow “the promptings of self”

Follow not the promptings of the self, for it summoneth insistently to wickedness and lust; follow, rather, Him Who is the Possessor of all created things, Who biddeth you to show forth piety, and manifest the fear of God. He, verily, is independent of all His creatures. (Baha'u'llah, 'The Kitab-i-Aqdas')

There are “laws … revealed to mankind in each age by the Manifestation of God”

Just as there are laws governing our physical lives, requiring that we must supply our bodies with certain foods, maintain them within a certain range of temperatures, and so forth, if we wish to avoid physical disabilities, so also there are laws governing our spiritual lives. These laws are revealed to mankind in each age by the Manifestation of God, and obedience to them is of vital importance if each human being, and mankind in general, is to develop properly and harmoniously. Moreover, these various aspects are interdependent. If an individual violates the spiritual laws for his own development he will cause injury not only to himself but to the society in which he lives. Similarly, the condition of society has a direct effect on the individuals who must live within it. (The Universal House of Justice, 'Messages from the Universal House of Justice 1968-1973')

Fasting and Obligatory prayer are like the sun and moon of the “heaven” of the “religion of God”

Cling firmly to obligatory prayer and fasting. Verily, the religion of God is like unto heaven; fasting is its sun, and obligatory prayer is its moon. In truth, they are the pillars of religion whereby the righteous are distinguished from those who transgress His commandments. We entreat God, exalted and glorified be He, that he may graciously enable all to observe that which He hath revealed in His Ancient Book. (Baha’u’llah, compilation on The Importance of Obligatory Prayer and Fasting)

Know thou that religion is as heaven; and fasting and obligatory prayer are its sun and its moon. We entreat God, exalted and glorified be He, to graciously aid everyone who acteth according to His will and good-pleasure. (Baha’u’llah, compilation on The Importance of Obligatory Prayer and Fasting)

All our acts should be distinguished by “integrity and uprightness”

Let integrity and uprightness distinguish all thine acts. (Baha'u'llah, 'Epistle to the Son of the Wolf')

We should strive to become more humble

“Be … a fruit upon the tree of humility.” (Baha'u'llah, 'Epistle to the Son of the Wolf')

“The goodliest vesture in the sight of God in this day is trustworthiness"

O people! The goodliest vesture in the sight of God in this day is trustworthiness. All bounty and honour shall be the portion of the soul that arrayeth itself with this greatest of adornments. (Baha’u’llah; 'The Compilation of Compilations vol. II')

Regard thou faith as a tree. Its fruits, leaves, boughs and branches are, and have ever been, trustworthiness, truthfulness, uprightness and forbearance. (Baha’u’llah, 'The Compilation of Compilations vol. II')

We should abstain from fault-finding and backbiting

Breathe not the sins of others so long as thou art a sinner. 
- Baha’u’llah  ('The Hidden Words')

The worst human quality and the most great sin is backbiting [“discussing the faults of others in their absence”], more especially when it emanates from the tongues of the believers of God. 
- ‘Abdu’l-Baha  (Quoted in Star of West, Vol. IV. p. 192; included in a letter written on behalf of Shoghi Effendi to the National Spiritual Assembly of the British Isles, February 11, 1925; 'Lights of Guidance')

On no subject are the Bahá'í teachings more emphatic than on the necessity to abstain from fault-finding and backbiting while being ever eager to discover and root out our own faults and overcome our own failings. 
- Shoghi Effendi  (From a letter written on behalf of the Guardian to an individual believer, May 12, 1925: 'Living the Life'; 'Lights of Guidance')

We should “observe moderation in all things”

Whatsoever passeth beyond the limits of moderation will cease to exert a beneficial influence. (Baha'u'llah, 'Gleanings from the Writings of Baha'u'llah')

The fundamental purpose of God’s religion is “to safeguard the interests and promote the unity of the human race, and to foster the spirit of love and fellowship amongst men.”

The fundamental purpose animating the Faith of God and His Religion is to safeguard the interests and promote the unity of the human race, and to foster the spirit of love and fellowship amongst men. Suffer it not to become a source of dissension and discord, of hate and enmity. This is the straight Path, the fixed and immovable foundation. Whatsoever is raised on this foundation, the changes and chances of the world can never impair its strength, nor will the revolution of countless centuries undermine its structure. (Baha'u'llah, 'Gleanings from the Writings of Baha'u'llah')

To be worthy of the trust of one's neighbor

Be worthy of the trust of thy neighbor, and look upon him with a bright and friendly face. (Baha’u’llah, 'Epistle to the Son of the Wolf')

“A good character is …the most excellent and praiseworthy of all things”

A good character is in the sight of God and His chosen ones and the possessors of insight, the most excellent and praiseworthy of all things, but always on condition that its center of emanation should be reason and knowledge and its base should be true moderation. (Abdu'l-Baha, The Secret of Divine Civilization)

We shouldn’t content with any one

Beware lest ye contend with any one, nay, strive to make him aware of the truth with kindly manner and most convincing exhortation. If your hearer respond, he will have responded to his own behoof, and if not, turn ye away from him, and set your faces towards God's sacred Court, the seat of resplendent holiness. (Baha'u'llah, Gleanings from the Writings of Baha'u'llah; Compilation of Compilations, vol. 3)

There “can be no extremes in human conditions as regards wealth and sustenance.”

One of Bahá'u'lláh's teachings is the adjustment of means of livelihood in human society. Under this adjustment there can be no extremes in human conditions as regards wealth and sustenance. For the community needs financier, farmer, merchant and laborer just as an army must be composed of commander, officers and privates. All cannot be commanders; all cannot be officers or privates. Each in his station in the social fabric must be competent -- each in his function according to ability but with justness of opportunity for all. (Abdu'l-Baha, The Promulgation of Universal Peace, p. 216)

“..no one should exalt himself over the other.”

O Children of Men! Know ye not why We created you all from the same dust? That no one should exalt himself over the other. Ponder at all times in your hearts how ye were created. Since We have created you all from one same substance it is incumbent on you to be even as one soul, to walk with the same feet, eat with the same mouth and dwell in the same land, that from your inmost being, by your deeds and actions, the signs of oneness and the essence of detachment may be made manifest. Such is My counsel to you, O concourse of light! Heed ye this counsel that ye may obtain the fruit of holiness from the tree of wondrous glory. (Baha’u’llah, ‘The Hidden Words of Bahá'u'lláh’; The Compilation of Compilations vol II, p. 357)

“The well-being of mankind, its peace and security, are unattainable unless and until its unity is firmly established.”

God's purpose in sending His Prophets unto men is twofold. The first is to liberate the children of men from the darkness of ignorance, and guide them to the light of true understanding. The second is to ensure the peace and tranquillity of mankind, and provide all the means by which they can be established. (Baha’u’llah, ‘Gleanings from the Writings of Bahá'u'lláh’ pp. 79-80; The Compilation of Compilations vol II, p. 151)

The well-being of mankind, its peace and security, are unattainable unless and until its unity is firmly established. This unity can never be achieved so long as the counsels which the Pen of the Most High hath revealed are suffered to pass unheeded. (Baha’u’llah, ‘Gleanings from the Writings of Bahá'u'lláh’, p. 286; The Compilation of Compilations vol II, p. 153)

“Every religion of the past was fit to become universal”

In the "Bayan" the Báb says that every religion of the past was fit to become universal. The only reason why they failed to attain that mark was the incompetence of their followers. He then proceeds to give a definite promise that this would not be the fate of the revelation of "Him Whom God would make manifest" [Baha'u'llah], that it will become universal and include all the people of the world. (From a letter dated 20 February 1932 written on behalf of Shoghi Effendi to an individual believer, The Compilation of Compilations vol II, p. 4)

Not to tell an untruth under all conditions

As to the question whether it is right to tell an untruth in order to save another, he feels that under no condition should we tell an untruth but at the same time try and help the person in a more legitimate manner. Of course it is not necessary to be too outspoken until the question is directly put to us. (From a letter written on behalf of Shoghi Effendi to an individual believer, December 21, 1927: Living the Life, p. 3; Lights of Guidance, p. 602)

Every person should have an occupation

Every person must have an occupation, a trade or a craft, so that he may carry other people's burdens, and not himself be a burden to others. (‘Abdu’l-Baha, The Compilation of Compilations vol. I, p. 3)

Baha’u’llah has revealed three special daily obligatory prayers – we are "entirely free to choose any one of” them.

The daily obligatory prayers are three in number. The shortest one consists of a single verse which has to be recited once in every twenty-four hours and at midday. The medium (prayer) which begins with the words: 'The Lord is witness that there is none other God but He,' has to be recited three times a day, in the morning, at noon and in the evening. The long prayer which is the most elaborate of the three has to be recited once in every twenty-four hours, and at any time one feels inclined to do so.

"The believer is entirely free to choose any one of those three prayers but is under the obligation of reciting one of them, and in accordance with any specific directions with which they may be accompanied.

"These daily obligatory prayers, together with a few other specific ones, such as the Healing Prayer, the Tablet of Ahmad, have been invested by Bahá'u'lláh with a special potency and significance, and should therefore be accepted as such and be recited by the believers with unquestioned faith and confidence, that through them they may enter into a much closer communion with God, and identify themselves more fully with His Laws and precepts." (Shoghi Effendi, from a letter written on his behalf, Directives from the Guardian, p. 59)

“Knowledge is as wings to man's life, and a ladder for his ascent.”

Knowledge is as wings to man's life, and a ladder for his ascent. Its acquisition is incumbent upon everyone. The knowledge of such sciences, however, should be acquired as can profit the peoples of the earth, and not those which begin with words and end with words. Great indeed is the claim of scientists and craftsmen on the peoples of the world. Unto this beareth witness the Mother Book on the day of His return.... (Baha’u’llah, ‘Tablets of Bahá'u'lláh Revealed After the Kitáb-i-Aqdas’, pp. 51-52; The Compilation of Compilations vol. I, p. 2)

“The purpose of religion …is to establish unity and concord amongst the peoples of the world..”

The purpose of religion as revealed from the heaven of God's holy Will is to establish unity and concord amongst the peoples of the world; make it not the cause of dissension and strife. The religion of God and His divine law are the most potent instruments and the surest of all means for the dawning of the light of unity amongst men. The progress of the world, the development of nations, the tranquillity of peoples, and the peace of all who dwell on earth are among the principles and ordinances of God. Religion bestoweth upon man the most precious of all gifts, offereth the cup of prosperity, imparteth eternal life, and showereth imperishable benefits upon mankind. It behoveth the chiefs and rulers of the world, and in particular the Trustees of God's House of Justice, to endeavour to the utmost of their power to safeguard its position, promote its interests and exalt its station in the eyes of the world. In like manner it is incumbent upon them to enquire into the conditions of their subjects and to acquaint themselves with the affairs and activities of the divers communities in their dominions. We call upon the manifestations of the power of God -- the sovereigns and rulers on earth -- to bestir themselves and do all in their power that haply they may banish discord from this world and illumine it with the light of concord. (Baha'u'llah, Tablets of Baha'u'llah)
