The Purification of the Blessed Virgin Mary
The propers of the Holy Mass will be for the Purification of the Blessed Virgin Mary, which is otherwise known as Candlemas.
"The feast of Candlemas, which derives its origin from the local observance of Jerusalem, marks the end of the Feasts included in the Christmas cycle of the Liturgy. It is perhaps the most ancient festival of Our Lady, commemorating not only the obedience of the Blessed Virgin to the Mosaic Law in going to Jerusalem forty days after the birth of her child, making the accustomed offerings, but also the Presentation of Our Lord in the Temple, and the meeting of the Infant Jesus with the old man Simeon, the Occursus Domini, as the Feast was anciently termed".
This is the principle theme of the liturgy today , Jesus taken to the temple to "present Him to the Lord"
