Summary: Balthasar chooses a specific historical-theological approach to the fundamental dogma of Christianity, which states that Jesus Christ redeems the world through the Cross, the descent into Hell, and the Resurrection, thereby revealing God as trinitarian love. He aims for a "genuine theological penetration" of the individual mysteries of salvation. To this end, he employs a contemplative-biblical approach that connects the narratives of the Synoptics with the deeper theological interpretations found in Paul and John. In his contemplation of the central mystery of Christ, Balthasar particularly highlights the trinitarian horizon and the ecclesiological consequences. In his comprehensive synthetic thinking, he attempts to unify all aspects of the mystery. Alongside Scripture, Balthasar consistently consults tradition, especially the Church Fathers. A primary concern of the author is the integration of the concrete theology of saints and mystics—particularly Adrienne von Speyr—into abstract dogmatic scholastic theology, as the saints better articulate the central "pro nobis" of the salvific event.
