‘But when the time had fully come, God sent forth his Son, born of a woman, born under the law, to redeem those who were under the law, so that we might receive adoption as sons.’ This is ‘the gospel of Jesus Christ, the Son of God’: God has visited his people. He has fulfilled the promise he made to Abraham and his descendants. He acted far beyond all expectation – he has sent his own ‘beloved Son’.
We believe and confess that Jesus of Nazareth, born a Jew of a daughter of Israel at Bethlehem at the time of King Herod the Great and the emperor Caesar Augustus, a carpenter by trade, who died crucified in Jerusalem under the procurator Pontius Pilate during the reign of the emperor Tiberius, is the eternal Son of God made man. He ‘came from God’, ‘descended from heaven’, and ‘came in the flesh’.For ‘the Word became flesh and dwelt among us, full of grace and truth; we have beheld his glory, glory as of the only Son from the Father. . . and from his fullness have we all received, grace upon grace.’
Moved by the grace of the Holy Spirit and drawn by the Father, we believe in Jesus and confess: ‘You are the Christ, the Son of the living God.’ On the rock of this faith confessed by St. Peter, Christ built his Church.
“To preach. . . the unsearchable riches of Christ”
The transmission of the Christian faith consists primarily in proclaiming Jesus Christ in order to lead others to faith in him. From the beginning, the first disciples burned with the desire to proclaim Christ: “We cannot but speak of what we have seen and heard.” It and they invite people of every era to enter into the joy of their communion with Christ:
That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon and touched with our hands, concerning the word of life – the life was made manifest, and we saw it, and testify to it, and proclaim to you the eternal life which was with the Father and was made manifest to us – that which we have seen and heard we proclaim also to you, so that you may have fellowship with us; and our fellowship is with the Father and with his Son Jesus Christ. and we are writing this that our joy may be complete.
