…the principle of unqualified and whole-hearted loyalty to the revealed Word. The believers should be careful not to deviate, even a hair-breadth, from the Teachings. Their supreme consideration should be to safeguard the purity of the principles, tenets and laws of the Faith. It is only by this means that they can hope to maintain the organic unity of the Cause. There can and should be no liberals or conservatives, no moderates or extremes in the Cause. For they are all subject to the one and the same law which is the Law of God. This law transcends all differences, all personal or local tendencies, moods and aspirations. 
- Shoghi Effendi  (From a letter dated July 10, 1936 written on behalf of Shoghi Effendi; ‘Dawn of a New Day’)
