This essay exposes the main Christological theses of Joseph Ratzinger, considering them in their internal unity and totality conferred by the concept of spiritual Christology . To this end, an analytical path is taken offering a unified view of the various areas of Ratzingerian Christology. The analytical dimension consists of approaching each moment of the Christological formula Jesus-Christ-Logos . The first moment concerns the historical character of Christology, which is dealt with diachronicly by raising the status quaestionis of critical research in search of the historical Jesus , and synchronously through the theology of the incarnation, which, in J. Ratzinger, does not separate from the theology of the cross. The second part of the formula concerns the profession of biblical faith in the man Jesus from the category Christ , whose broader context is analyzed through the following titles: prophet, Son of God and Lord. Finally, the third moment considers the Christology of the Logos in the broad framework provided by dogmatic Christology, as it developed until the 7th century in the third Council of Constantinople. The analysis of dogmatic Christology has as its preamble the discussion about the legitimacy of dogma s language, justifying the formal approach of the first councils that outlined Christological dogma. The analytical exposition of J. Ratzinger s Christology leads to the junction of theses - synthesis -, making the synthetic dimension emerge as the corollary of this research. The hypothesis raised as a conclusive opportunity consists in the understanding that the unity of the Ratzingerian spiritual Christology , although it is the result of a precise methodological approach, can be reduced to the minimum common denominator belonging to the three moments of the Christological formula: the relationality. Total relativity, historically manifested by the fact of prayer, belongs to the man Jesus, the professed Christ and the Logos of dogmatics.
