Economic ethics is a question of how economic action can be linked to the overall context of moral and ethical consciousness in order to bring economy and ethics into a productive relationship that aligns with the common good. Evangelical economic ethics is based on biblical tradition and speaks of it in the horizon of current questions. It makes clear content statements that are not based on human understanding but on divine revelation. We mean the commandments and orders of God, which also clearly regulate the modern economic life. Divine Revelation establishes binding, authority, and a priori values that are not questioned. Arthur Rich, in his reflections on evangelical economic ethics, tried to combine economic and ethical rationality, by discussing the criteria of justice and human rights and in this perspective developing the guiding principle of a socially and ecologically regulated market economy. The aspect of the "righteous man" is central, since maxims must always serve man and ultimately man remains referring to God's justice, even in situations of failure and guilt in the economic context. In this sense, the present work shows the foundations and conception of evangelical economic ethics, as exemplified by Arthur Rich. And then look for their application possibilities in practice.
