…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. (‘Abdu’l-Baha, quoted by the Universal House of Justice in a letter dated 7 April 2008, written on its behalf to the believers in Iran)
