The main purpose of the paper was to reinterpret Jesus Christ’s thought as a philosophy of adult education to achieve the sustainable inclusive society. Recently along with the labor market instability and the increase of unemployment and aggravated exclusion of the socially disadvantaged mainly stemmed from the global economic slump, the role of adult education for the inclusive society has been increasingly emphasized. UNESCO Delors Report already suggested ‘learning to live together’ for the inclusive society as an important pillar of adult education. The core of Jesus’ thought, as an adult educator, is also composed of inclusiveness. However even though both the Delors Report based on humanism and Jesus’ thought have in common in justifying the inclusiveness, the reason and purpose of the inclusiveness is totally differentiated. The study starts with defining Jesus Christ as an adult educator, and then compares the philosophical basement of the UNESCO report with Jesus’ inclusive thought. The paper then examines Jesus’ thought on inclusiveness from the four viewpoint of adult education, that is, the discovery of others through perspective transformation; community and practical inclusiveness education; liberation education for inclusive society; and existential meeting education for inclusive society. In conclusion the paper discusses the meaning of study Jesus’ thought, beyond the religious dimension, from the viewpoint of adult education.
