Troparion for the Feast of the Presentation of Christ to the Temple:
"Rejoice, O Virgin Theotokos, full of grace! From you shone the Sun of Righteousness, Christ our God, enlightening those who sat in darkness! Rejoice and be glad, O righteous elder; you accepted in your arms the Redeemer of our souls."
The Feast of the Presentation of Christ to the Temple takes place forty days after His birth. According to Jewish law, Mary and Joseph brought Jesus to the temple forty days after his birth, just as your parents bring you to be "churched" forty days after your birth. At this time you are presented to God to serve Him and His Holy Church.
Saint Simeon and Saint Anna were there at the time. Simeon was so happy when he held baby Jesus in his arms. He praised God saying, "Lord, now You are letting Your servant depart in peace, According to Your word. For my eyes have seen Your salvation which you have prepared before the face of all peoples, A light to bring revelation to the Gentiles, and the glory of Your people Israel." Simeon said he could now die in peace. He had seen the Saviour. Anna, a very old widow, was also very happy when she saw Jesus.
Read the story of the Presentation of Jesus to the Temple in Luke 2:25-38.
