Frederick Denny in Islam and the Muslim Community points out that one of the most noteworthy aspects of contemporary Islam is its growing prosperity in Europe, especially in countries of Christian dominance. Most recently, in the wake of rise of ISIS in Syria and influx of Muslim refugees to Europe, a newspaper reports, “There will eventually be more Muslims than Christians in Europe.” The growth of Islam is taking place not just in Europe. It is a worldwide trend, and the Muslim population is rapidly increasing in Korea as well. To better understand how best to meet the challenge of rising Muslim populations, specifically in England and in Korea, this article attempts to develop a Christian Christological response. To that end, the article first explores contemporaryMuslim trends in England and Korea with an eye toward understanding how to communicate the gospel to them effectively. This includes an examination of the Islamic Jesus portrayed in the Qur’an in comparison to Jesus, the Son of God in Christianity. As is known, pivotal to attaining a meaningful Christian-Muslim dialogue, as well as a credible Christian witness to Muslims, is the problem of Christology. Islam has a fairly well-developed Christology. However, the Christian message that “Jesus is the Son of God” is an abomination to the Muslims. Thus, Christians face crucial Christological questions whether they must avoid the term “Son of God” and instead defer to the name “Isa” for Jesus by which Muslims know him. Facing the obstacles in traditional Christian-Muslim dialogue, the article explores how best to stand on common ground with Muslims while satisfactorily and carefully articulating points of distinction, especially regarding the work of Christ. The article concludes by formulating an effective strategy for relating to and reaching Muslims theologically and culturally, while concretely manifesting Christian love in order to be the love of Christ to them and not just talk about it abstractly.
