Deus absconditus, Deus manifestus in den Mysterien des Lebens Jesu

This volume presents an original and historical-systematic study of the mysteries of Christ as a theology of revelation in the *Tertia Pars* of Thomas Aquinas’s *Summa Theologiae* (q.27–59). Two questions take center stage: Why does God hide Himself? How does He reveal Himself in Christ? The examination of Christ’s birth, baptism, Transfiguration, Passion, and Resurrection reveals a fascinating dynamic between Deus absconditus and Deus manifestus. Christ Himself embodies this paradox: in His humanity, His divinity is both veiled and revealed. The study explores the various meanings of God’s hidden nature and His manifestation. Deus absconditus is not a synonym for absence or unknowability, but rather a reticence rooted in the economy of salvation that carries within it a positive content of revelation. In resonance with the concept of the tzimtzum, the hidden God gives human beings the space to respond freely to divine revelation and to cooperate with Him. This study fills a significant gap in research and unfolds Aquinas’s thought with remarkable precision and interpretive depth. It lays a solid foundation for a renewed theology of revelation and nourishes the contemplative reflection on the mysteries of Christ as theophanies of the hidden God.
