The people that lived in darkness have seen a great light
Hearing that John had been arrested, Jesus went back to Galilee, and leaving Nazareth he went and settled in Capernaum, a lakeside town on the borders of Zebulun and Naphtali. In this way the prophecy of Isaiah was to be fulfilled:
‘Land of Zebulun! Land of Naphtali!
Way of the sea on the far side of Jordan,
Galilee of the nations!
The people that lived in darkness has seen a great light;
on those who dwell in the land and shadow of death
a light has dawned.’
From that moment Jesus began his preaching with the message, ‘Repent, for the kingdom of heaven is close at hand.’
He went round the whole of Galilee teaching in their synagogues, proclaiming the Good News of the kingdom and curing all kinds of diseases and sickness among the people. His fame spread throughout Syria, and those who were suffering from diseases and painful complaints of one kind or another, the possessed, epileptics, the paralysed, were all brought to him, and he cured them. Large crowds followed him, coming from Galilee, the Decapolis, Jerusalem, Judaea and Transjordania.
1 John 3:22-4:6
The Son of God has come and given us the power to know the true God
Whatever we ask God,
we shall receive,
because we keep his commandments
and live the kind of life that he wants.
His commandments are these:
that we believe in the name of his Son Jesus Christ
and that we love one another
as he told us to.
Whoever keeps his commandments
lives in God and God lives in him.
We know that he lives in us
by the Spirit that he has given us.
It is not every spirit, my dear people, that you can trust;
test them, to see if they come from God,
there are many false prophets, now, in the world.
You can tell the spirits that come from God by this:
every spirit which acknowledges that Jesus the Christ has come in the flesh
is from God;
but any spirit which will not say this of Jesus
is not from God,
but is the spirit of Antichrist,
whose coming you were warned about.
Well, now he is here, in the world.
you have already overcome these false prophets,
because you are from God and you have in you
one who is greater than anyone in this world;
as for them, they are of the world,
and so they speak the language of the world
and the world listens to them.
But we are children of God,
and those who know God listen to us;
those who are not of God refuse to listen to us.
This is how we can tell
the spirit of truth from the spirit of falsehood.

The mysteries of Jesus’ infancy
527 Jesus’ circumcision, on the eighth day after his birth, is the sign of his incorporation into Abraham’s descendants, into the people of the covenant. It is the sign of his submission to the Law and his deputation to Israel’s worship, in which he will participate throughout his life. This sign prefigures that “circumcision of Christ” which is Baptism.
528 The Epiphany is the manifestation of Jesus as Messiah of Israel, Son of God and Savior of the world. The great feast of Epiphany celebrates the adoration of Jesus by the wise men (magi) from the East, together with his baptism in the Jordan and the wedding feast at Cana in Galilee. In the magi, representatives of the neighboring pagan religions, the Gospel sees the first-fruits of the nations, who welcome the good news of salvation through the Incarnation. The magi’s coming to Jerusalem in order to pay homage to the king of the Jews shows that they seek in Israel, in the messianic light of the star of David, the one who will be king of the nations. Their coming means that pagans can discover Jesus and worship him as Son of God and Savior of the world only by turning towards the Jews and receiving from them the messianic promise as contained in the Old Testament. The Epiphany shows that “the full number of the nations” now takes its “place in the family of the patriarchs”, and acquires Israelitica dignitas (is made “worthy of the heritage of Israel”).
529 The presentation of Jesus in the temple shows him to be the firstborn Son who belongs to the Lord. With Simeon and Anna, all Israel awaits its encounter with the Savior-the name given to this event in the Byzantine tradition. Jesus is recognized as the long-expected Messiah, the “light to the nations” and the “glory of Israel”, but also “a sign that is spoken against”. The sword of sorrow predicted for Mary announces Christ’s perfect and unique oblation on the cross that will impart the salvation God had “prepared in the presence of all peoples”.
530 The flight into Egypt and the massacre of the innocents make manifest the opposition of darkness to the light: “He came to his own home, and his own people received him not.” Christ’s whole life was lived under the sign of persecution. His own share it with him. Jesus’ departure from Egypt recalls the exodus and presents him as the definitive liberator of God’s people.
Why do the nations protest and the peoples grumble in vain?
Kings on earth rise up and princes plot together against the LORD and his anointed:
“Let us break their shackles and cast off their chains!”
The one enthroned in heaven laughs; the Lord derides them,
Then speaks to them in anger, terrifies them in wrath:
“I myself have installed my king on Zion, my holy mountain.”
I will proclaim the decree of the LORD, who said to me, “You are my son; today I am your father.
Only ask it of me, and I will make your inheritance the nations, your possession the ends of the earth.
With an iron rod you shall shepherd them, like a clay pot you will shatter them.”
And now, kings, give heed; take warning, rulers on earth.
Serve the LORD with fear; with trembling bow down in homage, Lest God be angry and you perish from the way in a sudden blaze of anger. Happy are all who take refuge in God!
