Historical theology

Seminar for Catholic Theology

We explore historical theology and church history, the people of the past and their answers to the big questions of life. Old texts and old languages make our hearts beat faster. Theological texts, archaeological finds or historical works of art, church buildings, literature or music can be both the starting point and the content of our reflections. We consider how best to methodically get to the bottom of historical religious phenomena and work with classical historical methods as well as methods from the digital humanities.

History has made theology and the church what they are today. We look for historical traces of being Christian and being church, traces of theological activity and the struggle to shape Christian life. We try to understand these traces of the past from their contexts and make them fruitful for current theological discourse.
