…religious interests should not be brought into politics. Religions should treat of morals; politics of material circumstances. Those in authority should occupy themselves with the lives of men, they should teach ideas of service, good morals and develop the habit of Justice. "Render unto Caesar the things that are Caesar's, and unto God the things that are God's." In Persia there are among the most important ministers of state religious men who fear divine punishment; the others, however, do not think of the consequences of their acts. This is the reason why they have great difficulties in Persia.
Friends of God, set forth the example of Justice! Justice is a universal quality. From the highest to the lowest justice should be sacred; from the sovereign to the merchant, the minister of state to the artisan, all must be just. Be just, respect the rights of each man—"do unto others as you would have them do unto you." A workman who commits an injustice is as much to blame as a tyrant. Each one of us can choose between justice and injustice.
I hope you will be just in your relations with others, that you will never harm your fellows, that you will respect the rights of all men, and above all consider the rights of others before your own.
