The fact that the Faith, as the Guardian states, “enjoins upon its followers the primary duty of an unfettered search after truth", should reassure any aspiring Bahá’í historian that there can be no question of any requirement to distort history in the so-called “interests” of the Faith. On the contrary, the combination of profound faith and freedom of thought is one of the great strengths of the Bahá’í religion. It does, however, place a great responsibility upon Bahá’í historians to put forward their views and conclusions with moderation and due humility. In this connection one of the Tablets of Bahá’u’lláh states: Thou hast written that one of the friends hath composed a treatise. This was mentioned in the Holy Presence, and this is what was revealed in response: Great care should be exercised that whatever is written in these days doth not cause dissension, and invite the objection of the people. Whatever the friends of the one true God say in these days is listened to by the people of the world. It hath been revealed in the Lawh-i-Hikmat: “The unbelievers have inclined their ears towards Us in order to hear that which might enable them to cavil against God, the Help in Peril, the Self-Subsisting.” Whatever is written should not transgress the bounds of tact and wisdom, and in the words used there should lie hid the property of milk, so that the children of the world may be nurtured therewith, and attain maturity. We have said in the past that one word hath the influence of spring and causeth hearts to become fresh and verdant, while another is like unto blight which causeth the blossoms and flowers to wither. God grant that authors among the friends will write in such a way as would be acceptable to fair-minded souls, and not lead to cavilling by the people.
