The believers should be careful not to deviate, even a hair-breadth, from the Teachings. Next principle is complete, and immediate obedience to the Assemblies

“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.

Next is the principle of complete, and immediate obedience to the Assemblies, both local and national. It is the responsibility of these Bahá’í administrative bodies to enable the community to acquire, and increasingly deepen in the knowledge and understanding of the Cause. Doctrinal unity and administrative unity, these are the two chief pillars that sustain the edifice of the Cause, and protect it from the storms of opposition which so severely rage against it.”
