In 1964 medical mission was challenged and called to define its distinctiveness and its special role in the context of that particular time. The consultation "Tuebingen I" clearly stated: "The Christian church has a specific task in the field of health and healing"1, and developed a concept of wholeness and of the role of the congregation in health provision. 50 years later, the question of the proprium of Christian health services is again a very important one. At a time when governments, international non-governmental organizations and other philanthropic organizations participate in health care, the question has to be asked: What is the specific contribution of a Christian health service or ministry of healing? At a time when chronic disease challenges not only rich but now also poor countries, when infections like Ebola that for years were hidden in Africa pose a threat to the global situation, Christians have to reflect on the question of the proprium of Christian health care.
