The purpose of this study is to illuminate cardinal Kim Su Hwan’s point of view on poverty and economic justice. This article consists of three parts: The first part describes the spirituality of poverty in Christianity and the second part deals with the problem of poverty and economic justice in Korean society. In the third part, I examine the environmental destruction and Cardinal Kim’s thought on eco-justice. Cardinal Kim suggests a way to realize economic justice by reflecting on the spirituality of poverty in Christianity. For this, he recommends that Christians and the Church as a faithful community should carry the cross of salvation among the poor with Jesus Christ. Cardinal Kim especially takes note of farmers, city poor, unemployed and foreign workers who live in deteriorated surroundings. And considering miserable condition in North Korea, he insists not to forget the brotherly love. Moreover, pointing out economic justice which is being neglected because of rapid economic development, he encourages that genuine sharing and economic justice are possible through the just social structure and cleansing evil within each of us. Cardinal Kim recognizes the problem of economic unjustice is not only related to human beings but also to nature. Confronting environmental destruction, he says that eco-economic justice should be realized through the integrity of creation and the way of nature friendly life. Finally, Cardinal Kim recommends that we should see the raw face of poverty. He encourages us to empty our unconscious cravings and desires to control others, through the partnerships with the poor. He believes that this world will become closer to the Kingdom of God, when we live according the spirituality of poverty and we try to realize justice and peace in our society.
