Thomas Pröpper has significantly shaped German-speaking fundamental theology in recent years. In his anthropology, his systematic-theological summary, he provides answers to fundamental philosophical and theological questions about humanity: How should subjectivity and human freedom be understood? What does the imago Dei of humanity mean? What is the relationship between human sin and guilt and God's grace and salvific action? Pröpper's consistent integration of human freedom and divine salvific action, philosophically grounded and scientifically responsible, leads to a perspective on humanity that is unparalleled in German-speaking theology.
