Doing justice is a central imperative in Judaism, Christianity, and Islam. Buddhists are urged to be socially engaged. Hinduism, Taoism, Confucianism, and primal religions emphasize right relationships within communities as building blocks of justice.
This practice applies to the whole range of human interactions, and today it is also being extended to animals and the environment. It means that we deal fairly with others, recognizing the equality and dignity of all. It requires that we work to insure that all people, especially the poor and the weak, have access to opportunities. It assumes that none of us is free until all of us are.
Practice justice by demanding it. Words can be as forceful as deeds the prophets of old proved that. Name injustices when you see them. Speak boldly and put your body and your money where your mouth is. Stand up and be counted.
