After several introductory reflections, this article attempts to categorize the various ways of using the New Testament as a foundation for the church's missionary activity. Here the author argues that interpreters of the New Testament should avoid a "double reductionism," while aiming at a multidimensional interpretive approach. The Bible is not a single book with a single understanding of mission. Rather, it offers a variety of perspectives on what mission might look like. In a third part the author offers several hermeneutical observations, suggesting that "linear" hermeneutics should be replaced by a hermeneutics of conversation. To counteract the absolutizing of our own situation and experience, it is necessary to stimulate a cross-cultural missiological hermeneutics.
