The difficulty of teaching online because of the COVID-19 pandemic makes teachers not perform their roles properly. Teachers only send assignments and materials. The teacher focuses only on the final result of the student's assignment. This paper aims to examine the role of Christian teachers based on teleological philosophy within the framework of reformed theology, using the research methods of literature studies. The philosophy of teleology is a philosophy that believes that everything in the world has a purpose and that it becomes the basis of the assessment of the actions taken. The role of a Christian teacher is to be an agent of restoration and reconciliation for his students to become like Christ. The resultant effect of the role of a Christian teacher is good because the Bible also explains that the ultimate purpose of human life is to be like Christ. Therefore, when examined from the standpoint of teleological philosophy, any action taken by a Christian teacher is of true value. But people who have been corrupted by sin are more likely to sin. All aspects of human life have been tainted by sin, including the philosophy of life and worldview. Christian teachers need to have a Christian worldview and make the Bible the basis for their actions. To have a true worldview, the Christian teacher must understand God's word by reading it.
