If Christmas falls on Sunday, Monday or Tuesday, one sunday falls Christmas and Epiphany. That Sunday would be Finding of the Lord in the Temple.
If Christmas falls on Wednesday, Thursday, Friday or Saturday, two Sundays fall between Christmas and Epiphany. The second Sunday would be Finding of the Lord in the Temple. The readings of the first Sunday would be the following.
Jer 23: 5-8
See, days are coming—oracle of the LORD— when I will raise up a righteous branch for David; As king he shall reign and govern wisely, he shall do what is just and right in the land. In his days Judah shall be saved, Israel shall dwell in security. This is the name to be given him: “The LORD our justice.” Therefore, the days are coming—oracle of the LORD—when they shall no longer say, “As the LORD lives, who brought the Israelites out of the land of Egypt”; but rather, “As the LORD lives, who brought the descendants of the house of Israel up from the land of the north”—and from all the lands to which I banished them; they shall again live on their own soil.
