"I sometimes think of myself as a "residual colonialist" – a Westerner dropped in Africa by birth and entangled with Africa without his consent. What am I doing here? Well, this is my home and I love it.klaus-thumb I am a Christian. A Lutheran. A committed ecumenist. I believe that there is only one church of Christ, but there are various gifts to serve each other, and various insights to correct and enrich each other. I am a theologian. But I also have a natural sciences and economics background. My passion has been to translate the biblical message into thought patterns of today. I work on an interdisciplinary basis. I have been called to serve a predominantly black church in South Africa. African traditional spirituality, its interaction with modernity and the social consequences have fascinated and challenged me. As a privileged person I am afflicted by the discrepancies in income and life chances between economic centres and peripheries. I devoted a considerable part of my career on causes and possible remedies. With many of my generation I have witnessed the agonies and conflicts produced by nationalism, colonialism and apartheid. I cannot shake off the burden of my belonging to the perpetrators. On the website you will find a list of my publications, abstracts of my major books, some ad hoc 'position papers' on selected themes, chapters from recent books, and a few recent sermons and songs. Here follows my life story for those who need to know more."
