This text argues for the single divine subjectivity of Christ, and describes how it encompasses a full and authentic humanity in Jesus - a human experience that is not overwhelmed by the divine presence, but fostered and enhanced by it.
The book explores the theological disputes surrounding Theodore of Mopsuestia, who was linked to Nestorius, the Archbishop of Constantinople. It addresses claims that Theodore's teachings on Christ's divinity and the Theotokos contributed to the Nestorian heresy. Initially viewed as an orthodox figure, Theodore faced condemnation at the Ecumenical Council of Ephesus. St. Cyril's work, likely written between Theodore's death and the council, aims to clarify these complex theological issues and the historical context of the early Church's debates.
