The ethical vision expressed in the Wonbulgyo Scriptures is gathered above all around the Threefold Study, which functions as a comprehensive discipline of mind, understanding, and conduct. Spiritual cultivation (jeongsin suyang) calls for a mind that is clear, alert, and free from greed, anger, and delusion, maintained through meditation, mindfulness, and reflective inquiry. Inquiry into human affairs and universal principles (sari yeongu) requires a careful examination of causes and conditions, seeking to live in accord with truth and justice rather than narrow self-interest. Choice in action (often framed as choosing right karma or righteous action) emphasizes deliberate, responsible conduct grounded in compassion and social responsibility. These three dimensions are not merely theoretical; they are meant to permeate daily life so that ethical discernment becomes a continuous practice.

Alongside this framework, the Scriptures articulate explicit moral precepts that parallel the traditional Buddhist five precepts, adapted to a modern, lay-centered context. Respect for life entails refraining from killing or harming living beings and nurturing a compassionate, non-violent attitude. Respect for property and social justice prohibits stealing, cheating, or exploitation, and encourages honesty and fairness in economic and social relations. Sexual conduct is to be kept pure, avoiding adultery and exploitation and grounding relationships in mutual respect and responsibility. Truthful speech rejects lying, slander, harsh words, and divisive talk, favoring speech that is accurate, kind, and conducive to harmony. Sobriety and clarity of mind require avoiding intoxicants and addictions that cloud judgment and damage oneself or others, thereby preserving the conditions for practice and service.

A distinctive feature of Wonbulgyo ethics is the orientation provided by the Fourfold Grace, which frames moral life as a response of gratitude. The grace of Heaven and Earth calls for ecological and existential appreciation, together with a resolve not to harm the natural world that sustains life. The grace of parents is honored through filial piety, care, and gratitude, recognizing the foundational role of family. The grace of fellow beings invites respect for all who support one’s existence, fostering cooperation, justice, and compassion in human relationships. The grace of laws and social institutions encourages obedience to just laws and active contribution to the public good, including efforts toward a more equitable social order. In this way, ethical practice becomes a continual effort to “repay” these intertwined forms of grace.

Finally, the Wonbulgyo Scriptures extend these principles into concrete guidance for everyday conduct, so that spiritual cultivation and social engagement are held together rather than set in opposition. Practitioners are encouraged to balance personal practice with service to others, embodying frugality, diligence, and simplicity in their way of life. There is an explicit rejection of fanatical sectarianism, superstition, and discriminatory attitudes, coupled with an emphasis on equality across gender and class. Family and workplace relationships are to be marked by mutual respect and responsibility, so that religious practice is not confined to temples or formal rituals but is woven into ordinary tasks and social roles. Through this integration, the ethical precepts of Wonbulgyo become a path for transforming both character and community.
