"O unitarians, make firm the girdle of endeavor, that perchance religious strife and conflict may be removed from amongst the people of the world and be annulled."

“He is God, exalted is His state, wisdom and utterance. The True One (glorious is His glory) for the showing forth of the gems of ideals from the mine of man, hath, in every age, sent a Trusted One. The primary foundation of the faith of God and the religion of God is this, that they should not make diverse sects and various paths the cause and reason of hatred. These principles and laws and firm sure roads appear from one dawning-place and shine from one dayspring, and these diversities were out of regard for the requirements of the time, season, ages, and epochs. O unitarians, make firm the girdle of endeavor, that perchance religious strife and conflict may be removed from amongst the people of the world and be annulled. For love of God and His servants engage in this great and mighty matter. Religious hatred and rancor is a world-consuming fire, and the quenching thereof most arduous, unless the hand of Divine Might give men deliverance from this unfruitful calamity. Consider a war which happeneth between two states: both sides have foregone wealth and life: how many villages were beheld as though they were not! This precept is in the position of the light in the lamp of utterance.”
