"Traditionally the Western term "Candlemas" (or Candle Mass) referred to the practice whereby a priest on 2 February blessed beeswax candles for use throughout the year, some of which were distributed to the faithful for use in the home."
Almighty and everliving God, we humbly pray that, as your only-begotten Son was this day presented in the temple, so we may be presented to you with pure and clean hearts by Jesus Christ our Lord; who lives and reigns with you and the Holy Spirit, one God, now and for ever. Amen.

22 When the time came for their ritual cleansing, in accordance with the Law of Moses, they brought Jesus up to Jerusalem to present him to the Lord. 23 (It’s written in the Law of the Lord, “Every firstborn male will be dedicated to the Lord.”) 24 They offered a sacrifice in keeping with what’s stated in the Law of the Lord, A pair of turtledoves or two young pigeons.
25 A man named Simeon was in Jerusalem. He was righteous and devout. He eagerly anticipated the restoration of Israel, and the Holy Spirit rested on him. 26 The Holy Spirit revealed to him that he wouldn’t die before he had seen the Lord’s Christ. 27 Led by the Spirit, he went into the temple area. Meanwhile, Jesus’ parents brought the child to the temple so that they could do what was customary under the Law. 28 Simeon took Jesus in his arms and praised God. He said,
29 “Now, master, let your servant go in peace according to your word,
30 because my eyes have seen your salvation.
31 You prepared this salvation in the presence of all peoples.
32 It’s a light for revelation to the Gentiles
and a glory for your people Israel.”
33 His father and mother were amazed by what was said about him. 34 Simeon blessed them and said to Mary his mother, “This boy is assigned to be the cause of the falling and rising of many in Israel and to be a sign that generates opposition 35 so that the inner thoughts of many will be revealed. And a sword will pierce your innermost being too.”
36 There was also a prophet, Anna the daughter of Phanuel, who belonged to the tribe of Asher. She was very old. After she married, she lived with her husband for seven years. 37 She was now an eighty-four-year-old widow. She never left the temple area but worshipped God with fasting and prayer night and day. 38 She approached at that very moment and began to praise God and to speak about Jesus to everyone who was looking forward to the redemption of Jerusalem.
39 When Mary and Joseph had completed everything required by the Law of the Lord, they returned to their hometown, Nazareth in Galilee. 40 The child grew up and became strong. He was filled with wisdom, and God’s favor was on him.
