No permanent schisms possible

The appointment of a Center of the Covenant protects against schisms, making it impossible for anyone to create a new sect or faction (though be wary of those attempting)

"As to the most great characteristic of the revelation of Bahá'u'lláh, a specific teaching not given by any of the Prophets of the past: It is the ordination and appointment of the Center of the Covenant. By this appointment and provision He has safeguarded and protected the religion of God against differences and schisms, making it impossible for anyone to create a new sect or faction of belief. To ensure unity and agreement He has entered into a Covenant with all the people of the world, including the interpreter and explainer of His teachings, so that no one may interpret or explain the religion of God according to his own view or opinion and thus create a sect founded upon his individual understanding of the divine Words. The Book of the Covenant or Testament of Bahá'u'lláh is the means of preventing such a possibility, for whosoever shall speak from the authority of himself alone shall be degraded. Be ye informed and cognizant of this. Beware lest anyone shall secretly question or deny this to you. There are some people of self-will and desire who do not communicate their intentions to you in clear language. They envelop their meanings in secret statements and insinuations. For instance, they praise a certain individual, saying he is wise and learned, that he was glorified in the presence of Bahá'u'lláh, conveying this to you in an insidious way or by innuendos. Be ye aware of this! Be awakened and enlightened! For Christ has said that no one hides the lamp under a bushel. The purport of my admonition is that certain people will endeavor to influence you in the direction of their own personal views and opinions. Therefore, be upon your guard in order that none may assail the oneness and integrity of Bahá'u'lláh's Cause. Praise be to God! Bahá'u'lláh left nothing unsaid. He explained everything. He left no room for anything further to be said. Yet there are some who for the sake of personal interest and prestige will attempt to sow the seeds of sedition and disloyalty among you. To protect and safeguard the religion of God from this and all other attack, the Center of the Covenant has been named and appointed by Bahá'u'lláh. Therefore, if anyone should set forth a statement in praise or recognition of another than this appointed Center, you must ask him to produce a written proof of the authority he follows. Let him show you a trace from the pen of the Center of the Covenant Himself, substantiating his praise and support of any other than the rightful one. Inform him that you are not permitted to accept the words of everyone. Say to him, "It is possible to love and praise a person today, to accept and follow another tomorrow and still another next day. Therefore, we cannot afford to listen to this or that individual. Where are your proofs and writings? Where is your authority from the pen of the Center of the Covenant?""

('Abdu'l-Bahá, Promulgation of Universal Peace, pp. 455-456)

Were it not for the Covenant, a thousand sects would arise among the Bahá'ís

"Were it not for the protecting power of the Covenant to guard the impregnable fort of the Cause of God, there would arise among the Baha'is, in one day, a thousand different sects as was the case in former ages. But in this Blessed Dispensation, for the sake of the permanency of the Cause of God and the avoidance of dissension amongst the people of God, the Blessed Beauty (may my soul be a sacrifice unto Him), has through the Supreme Pen written the Covenant and the Testament; He appointed a Center, the Exponent of the Book and the annuller of disputes. Whatever is written or said by Him is conformable to the truth and under the protection of the Blessed Beauty. He is infallible. The express purpose of this last Will and Testament is to set aside disputes from the world."

('Abdu'l-Bahá, Bahá'í World Faith, pp. 357-358)

Avowed and secret enemies of the Faith could never create a permanent cleavage in the vast body of its adherents

"The utmost its avowed and secret enemies could hope to achieve was to retard its growth and obscure momentarily its purpose. What they actually accomplished was to purge and purify its life, to stir it to still greater depths, to galvanize its soul, to prune its institutions, and cement its unity. A schism, a permanent cleavage in the vast body of its adherents, they could never create."

(Shoghi Effendi, World Order of Bahá'u'lláh, pp. 195-196)

Prophet Himself has established its institutions which is among its guarantees against schism

"It should be noted in this connection that this Administrative Order is fundamentally different from anything that any Prophet has previously established, inasmuch as Bahá'u'lláh has Himself revealed its principles, established its institutions, appointed the person to interpret His Word and conferred the necessary authority on the body designed to supplement and apply His legislative ordinances. Therein lies the secret of its strength, its fundamental distinction, and the guarantee against disintegration and schism."
