This research aims to introspect the matters of textbook on religion in the schools of religious foundation from the view of subject. The significance of the subjects on religion in the schools is to give a chance for students to realize the meanings of their life and to contemplate their inner wor lds. It takes pr ior ity over all else, including the teaching the religious doctrines, dogmatic knowledges, and all the rest of it. The inflexible view of subject makes the religion class so stiff and formal that teacher cannot interact with the students dynamically. There are no free imaginations and critical eyes about religions in that classroom. The text on religion is not just ‘interpreted’ system, but ‘should be interpreted’ one. It means the text on religion cannot be the absolute scriptures like canon in the religion. It is one the way of motivations for stimulating the interaction between teacher and student. So the subject is created and formed in every kinds of class situation. The usefulness of texts is not in the inner side of it, but in the dynamic context of the class. In the class of religion, students are expected to interact with the teacher as creative interpreters and critics about the text.
