Today the Church celebrates the feast of the Presentation of the Lord which occurs forty days after the birth of Jesus and is also known as Candlemas day, since the blessing and procession of candles is included in today's liturgy.
According to the 1962 Missal of St. John XXIII the Extraordinary Form of the Roman Rite, today is referred to as the "Purification of Mary." This is known as a "Christmas feast" since it points back to the Solemnity of Christmas. Many Catholics practice the tradition of keeping out the Nativity creche or other Christmas decorations until this feast.
PRESENTATION OF THE LORD
The feast was first observed in the Eastern Church as "The Encounter." In the sixth century, it began to be observed in the West: in Rome with a more penitential character and in Gaul (France) with solemn blessings and processions of candles, popularly known as "Candlemas." The Presentation of the Lord concludes the celebration of the Nativity and with the offerings of the Virgin Mother and the prophecy of Simeon, the events now point toward Easter.
"In obedience to the Old Law, the Lord Jesus, the first-born, was presented in the Temple by his Blessed Mother and his foster father. This is another 'epiphany' celebration insofar as the Christ Child is revealed as the Messiah through the canticle and words of Simeon and the testimony of Anna the prophetess. Christ is the light of the nations, hence the blessing and procession of candles on this day. In the Middle Ages this feast of the Purification of the Blessed Virgin Mary, or 'Candlemas,' was of great importance.
"The specific liturgy of this Candlemas feast, the blessing of candles, is not as widely celebrated as it should be, except of course whenever February 2 falls on a Sunday and thus takes precedence. There are two ways of celebrating the ceremony, either the Procession, which begins at a 'gathering place' outside the church, or the Solemn Entrance, celebrated within the church."
THINGS TO DO:
Ask your parish priest to bless the candles that you will be using on your home altar this year.
Have a family Candlemas procession
Read Luke 2:22-35, the account of the presentation including the Canticle of Simeon.
Meditate on the constant fiat of Our Lady of Sorrows, who embraced the will of God even as Simeon predicted that a sword would pierce her heart.
