|Presentation at the Temple by Ambrogio Lorenzetti, 1342|
Pope Benedict XVI's sermon of 2010 for the feast explains:
"On the Feast of the Presentation of Jesus in the Temple we are celebrating a mystery of Christ's life linked to the precept of Mosaic Law which prescribed that 40 days after the birth of their first-born child parents should go to the Temple of Jerusalem to offer the infant to the Lord and for the ritual purification of the mother (cf. Ex 13:1-2, 11-16; Lv 12:1-8). Mary and Joseph also fulfilled this rite, offering to comply with the law a couple of turtle doves or pigeons. In giving a deeper interpretation to these things we understand that at this moment it is God himself who is presenting his Only-Begotten Son to humanity through the words of the elderly Simeon and the Prophetess Anna. Simeon, in fact, proclaimed Jesus as the "salvation" of humanity, a "light" for all the nations and a "sign that is spoken against", because he would reveal the thoughts of hearts (cf. Lk 2:29-35). In the East this Feast was called Hypapante, a feast of encounter. In fact, Simeon and Anna, who met Jesus in the Temple and recognized him as the Messiah so long awaited, represent humanity that encounters its Lord in the Church. Subsequently, this Feast also spread to the West, where above all the symbol of light and the procession with candles which gave rise to the term "Candlemas" developed. This visible sign is intended to mean that the Church encounters in faith the One who is "the light of men" and in order to bring this "light" into the world, receives him with the full dynamism of her faith.
In conjunction with this Liturgical Feast, as from 1997, Venerable John Paul II decreed that a special Day of Consecrated Life be celebrated in the whole Church. In fact, the sacrifice of the Son of God symbolized by his presentation in the Temple is the model for every man and woman who consecrate their life totally to the Lord. The purpose of this Day is threefold: first of all to praise and thank the Lord for the gift of consecrated life; secondly to promote knowledge and appreciation of it among the whole People of God and lastly to invite all those who have dedicated their life totally to the cause of the Gospel to celebrate the marvels that the Lord has worked in them. As I thank you for coming here in such numbers, on this Day dedicated particularly to you I would like to greet each one of you with great affection men and women religious and consecrated people and to express to you my cordial closeness and heartfelt appreciation for the good you do at the service of the People of God."
