St. Paul, in his Letter to the Ephesians, speaking about the blessings, we have received in Christ, states: “He has made known(revealed) to us in all wisdom and insight the mystery of his will, according to his purpose which he set forth in Christ as a plan for the fulness of time, to unite all things in him, things in heaven and things on earth” (Ephesians 1:9-10).
Even from the beginning of the human history, God revealed Himself and entered into a covenantal relationship. God called Abraham to be the father of all nations. Then through Moses and the Prophets, He made Himself known to His chosen people as a loving Father, guided them as a shepherd through the desert to the fertile land flowing with milk and honey and forgave them of their unfaithfulness as a compassionate and merciful Father. Thus, through His people of Israel, He prepared the way for the coming of Jesus Christ.
The invisible God was pleased to reveal Himself as a personal being through Jesus Christ, the Incarnate Word of God, the Word made flesh in the Holy Spirit, in order that we may be able to understand and experience God’s love. Having revealed Himself as a personal God, He invites us to respond to Him by our love and personal relationship. Thus, we are privileged through Jesus Christ, to share in His own life.
Jesus Christ, as the Word made flesh, is the fulness of revelation as well as the mediator between us and our heavenly Father. God revealed Himself progressively to humankind, through the Prophets and through the various events in the Salvation History, until He brought to completion His self-revelation by sending His own Son (Cf. Hebrews 1:1-2). Jesus Christ completed and perfected the Revelation by His words and deeds, signs and miracles, above all by His death and resurrection and finally by sending the Spirit of truth.
Thus, the fulness of the Divine Revelation was accomplished in history by Jesus Christ. This is what we learn from the Sacred Scripture and the Sacred Tradition. Both the Sacred Scripture and Tradition are bound closely together and they constitute the deposit of our faith. Sacred Scripture is the Word of God written by human authors under the inspiration of the Holy Spirit; the Tradition transmits the Word of God, entrusted to the Apostles by Jesus Christ. (Cf. Catechism of the Catholic Church No.80 & 81).
