For too long a time, the contemporary theories of justice have been focusing on humankind as the sole bearer or claimant of justice and too little importance has been given to nature or the cosmos as the bearer of justice in its own right. Due to this limitation, ecological justice in particular has not been given the priority it deserves in the study of justice. Given the sacred character of nature or cosmos, God has not been considered an integral part of the study of justice, and further, that protecting nature has not been considered an important moral and sacred duty. This study presents a wholesome and all encompassing macro-theory of justice, Umumtulogy, by demonstrating how humankind, God, and nature are inter-related, and how harmony, peace, and abundant life in the world can be the fruit of a three-fold relationship.
