The link to Judaism is part of the Christian identity. This has consequences in regards to the formulation of Christian theology. The own history – as a German and as a Christian – has to be accepted, traditions are to be checked and updated in such a way, that they serve life – not lastly for “the lives of the others.” This is what has been attempted through the interpretation of New Testament texts on central theologian topics. Here, the rigid dogmatic formulas of biblical statements and their Jewish context are being realised. The insights gained through the bible place Christians side by side with Jews whilst respecting remaining differences as part of a solidary partnership.
