This research aims to analyze the impact of teaching Christian values based on Galatians 5:22-23 on the development of students' ethics in the Christian education environment. The focus of this study is to explore the extent to which values such as love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control can shape students' character and influence their attitudes and behaviors. The research method used is a case study involving students from several Christian educational institutions. Data is collected through classroom observations, interviews with teachers and students, and analysis of relevant literature. Data collection is conducted using a qualitative approach to gain a deep understanding of the teaching of Christian values and students' responses to these values. The results of this research provide insights into how the teaching of Christian values based on Galatians 5:22-23 contributes to the formation of students' ethics. Findings include students' understanding of Christian values, identified behavioral changes, and supporting or inhibiting factors in the implementation of these values in the educational environment. This research is expected to contribute to the development of more effective and relevant strategies for teaching Christian values and provide a deeper understanding of the impact of teaching Christian values on students' ethics. The implications of this research may assist educators and Christian educational institutions in better guiding students in the development of moral character in accordance with Biblical teachings.
