In the old rite (Latin) which I call universal the period of The Solemnity of Christmas (the way Christmas was observed) included Sundays following Christmas and went beyond New Year ending at the Feast of the Holy Family. Which went past the Epiphany and the Feast of the Holy Innocents and the Flight into Egypt.
What were those Sundays liturgy (gospel and other readings) dedicated to ? They were on events as the Child consummated God’s compact with the Jews before and after Circumcision (New Tear). I’m asking because I forget what they were.
