Council of Chalcedon, fourth ecumenical council of Catholic Church, taken place in 451, professes and defines solemnly the Jesus Christ s wide humanity and wide divinity, eternal incarnated Logos, combined in just one Person. The responsible for all the controversy that will be the key to the Council is the presbyter Eutyches, whose ideas to refuse Nestorian heresy fell in the opposite mistake: monophysitism. From that moment on, the Council creates a dogmatic formula, still current. The present thesis, throughout a historical and theological approach, developes the Christology theme of Council of Chalcedon, from preceeded Christology, through its dogmatic formula, until the currency of the theme in the analyzation of contemporain Christology between Catholics theologians, Protestants and Orthodox.
