Jesus Christ, the Prince of Peace, is a theological study of the theme of the Biblical peace, centering on its relationship with the person and the message of Jesus Christ. It summarizes evangelical requirements of an Ethics and of a pastoral action committed to the building of peace. The interest in the study of Biblical peace has its foundations on the fact that peace - a desire of the various peoples throughout history - is present in the Biblical texts when they speak of God`s relationship to humanity and of His salvation project. Departing from an analysis of certain texts of the Old one the New Testament this work tries systemize all the richness and complexity of the theme of Biblical peace. Its main objective is to show how the event Jesus Christ gives a new meaning to this theme. In His person and in His message rests the full meaning of what Biblical peace is, since it is contained in the very process of the Revelation of the face of God, the Father, and in the announcement and establishment of His Kingdom as well. In this fashion, this dissertation shows that a Theology and a Christian Ethics of peace have their foundation on the person and on the message of Jesus Christ.
