What was a primary focus of the Fourth Ecumenical Council, Chalcedon?

The Fourth Ecumenical Council, held in Chalcedon in 451 AD, primarily focused on addressing the relationship between the divine and human natures of Christ. This was a pivotal moment in Christian theology as the council sought to clarify doctrinal disputes arising from various interpretations of Christ's nature. The council produced the Chalcedonian Definition, which articulated the belief that Jesus Christ is acknowledged in two natures, one divine and one human, that are united in one person without confusion, change, division, or separation. This formulation was crucial in countering the teachings of various heretical groups that denied either the full humanity or full divinity of Christ, ensuring a more precise understanding of the Incarnation within mainstream Christianity.

The emphasis on Christ's dual natures at Chalcedon had lasting implications for Christian doctrine and unity, shaping the way the person of Jesus is understood within various Christian traditions. The focus on this theological aspect distinguished this council from others that dealt with issues like papal authority, Mariology, or sacramental theology.
