The line is just saying that you must believe in something. This line breaks down all the boundaries that have been imagined by mankind. It simply means that all men and women are equal. This tenet of the creed simply means that no one should be above the law, and that the law should be the same for all people, no matter what status they hold in society. The government must be based on constitutional law, accepted and ratified by a majority of the people.
Every individual has a separate and unique personality.
That is the main difference between humans and other creatures of the world. That uniqueness makes the human personality earth's greatest treasure. And that service to humanity is the best work of life. Joy is more enduring and peace of mind, more certain. No matter how an individual member interprets the Creed, he or she should always practice whatever he or she believes.
