All religions try to get their members to adhere to their purpose and goal. I run a couple of small companies. I have a business vision. Is it wrong to ask my employees to adhere to my vision and not deviate too far from it?
What about a franchise? A franchisor has to develop rules and regulations down to the finest detail. A franchisee is not allowed to deviate one iota from the written plan. Imagine if McDonalds franchises went astray. What would happen? The brand would be damaged. Similar, any organized religion must have certain stipulations or the brand, or religion, will be damaged or altered. Consistency must be maintained, or as we know it, unity.
