For Joseph Ratzinger, the separation between ontology and history constitutes the crucial problem that underlies all the difficulties of contemporary dogmatic theology since it affected the original unity of two essential dimensions of Christian revelation. This study delves into Joseph Ratzinger's approach to the problem, his account of the path that led to this separation, and into some key insights, drawn from his understanding of human salvation that could contribute to overcoming this dichotomy that afflicts contemporary theology. Through the study of Joseph Ratzinger's writings, Troconis highlights the relational and existential character of the theology of one of the best-known and most influential Catholic thinkers of our time.
