If there is one Sunday between the Glorious Birth of Our Lord and the Epiphany, the Finding of the Lord in the Temple is celebrated. If there are two Sundays between these feasts, the Glorious Birth of Our Lord is celebrated on the first Sunday and the Finding of the Lord in the Temple on the second Sunday.
Thus the Sunday after Christmas in the Maronite calendar is a reiteration of Christmas. (I believe that this is relatively new, and that the previous custom was that it was the Finding of the Lord in the Temple, rather than Christmas, that was twinned in two-Sunday years; at least, I have an old PDF of an English translation of the Qurbono in which this is pretty clearly how it was structured, although I cannot say that it was a universal rather than a local thing. There is also an exception to the above norm, which we will see this next year: the Feast of the Circumcision is always on January 1, so when the first of two Sundays after Christmas falls on January 1, it is the Feast of the Circumcision that is celebrated.)
Sunday after the Glorious Birth
2 Corinthians 11:1-11; Matthew 23:29-24:2
The Word of God Himself was made flesh,
from the Virgin Mary He was born;
He took the Church for His spotless Bride.
If any preaches another Christ,
he does not bring the good news of Christ,
he does not bring the Spirit of Christ,
he beguiles like a cunning serpent.
Israel's saints prepared for His birth,
Abraham, David, and the prophets;
He is the Lamb upon God's high throne.
If any preaches another Christ,
he does not bring the good news of Christ,
he does not bring the Spirit of Christ,
he beguiles like a cunning serpent.
He is greater than angels on high;
He is King of kings and Lord of lords;
He is the good and loving Shepherd.
If any preaches another Christ,
he does not bring the good news of Christ,
he does not bring the Spirit of Christ,
he beguiles like a cunning serpent.
From the Father He has come to us;
of the Father He is the icon;
save through Him the Spirit does not come.
If any preaches another Christ,
he does not bring the good news of Christ,
he does not bring the Spirit of Christ,
he beguiles like a cunning serpent.
Christ our Lord upon the cross was hung
to raise us to salvation and joy;
in His holy martyrs He is seen.
If any preaches another Christ,
he does not bring the good news of Christ,
he does not bring the Spirit of Christ,
he beguiles like a cunning serpent.
