Dasuk Ryu Youngmo (多夕 柳永模, 1890-1981) is assumed as an intellectual in early modern Korea, who had a Koreanized-Christian spirituality. He was a mainstream Christian in his youth. However, Ryu had attempted to convert Western Christianity into Korean context since he was 23 years old. His ideas were well presented in the doctrine of God and Christology, which were based on his personal spiritual experiences. He denied the personalized God of Christianity and the divinity of Christ. He believed that one can become the son of God if realizing the eol (soul) that was bestowed on human beings. This idea was originated from the teachings of Confucianism, Buddhism in Korea, which he studied throughout his entire life. Just as Korean religiosity is often considered the mixture of Korean religions, Dasuk ’s belief can be understood as a Koreanized Christianity. In this article, the author describes the religious ethos of Dasuk by tracing his creative interpretation of Christianity.
