Luther and the Trinity theology - On Oswald Bayer: Martin Luther's theology. A visualisation

My short (ecumenical) contribution is a reading of two texts by Luther that play an important role in Bayers book, especially where the theology of the Trinity is concerned: the hymn << Nun freut euch lieben Christen g'mein >> and a passage from the Great Catechism (the end of the commentary on the Creed). Bayer, in his analysis of the hymn uses two contrasts that should highlight the new insights of Luther: one is concerned with the motivum incarnationis, the other with the theology of the Trinity On the basis of research in Aquinas and recent developments in the theology of the Trinity these contrasts need to be nuanced. Bayers interpretation of the passage from the Great Catechism overlooks the distinction Luther makes between true and false Christians and because of his strong and almost exclusive emphasis on the role of Jesus Christ overlooks that Luther acknowledges clearly the importance of the role of the Spirit.
