Note: Here is a copy of the prayers (before each decade) that we used when we prayed the rosary together. You can use the commentary I wrote or change it to better suit your guest of honor.

The angel Gabriel was sent from God to a city of Galilee called Nazareth, to a virgin betrothed to a man whose name was Joseph. The angel said to Mary, “Hail full of grace! The Lord is with you. Behold, you will conceive in your womb and bear a son, and you shall call his name Jesus. Mary said, “Behold, I am the handmaid of the Lord; let it be to me according to your word.” (Luke 1:26-29, 38)
Blessed Mother, through your humility and obedience God’s plan of salvation was put into motion by a simple “yes.” May (NAME) be given the grace to say yes to God in the small and big things of her life, so that she, too, may participate in God’s plan of salvation through her vocation as a wife and mother.
Mary entered the house of Zechariah and greeted Elizabeth. When Elizabeth heard the greeting of Mary, the baby leaped in her womb; and Elizabeth was filled with the Holy Spirit and she exclaimed with a loud cry, “Blessed are you among women, and blessed is the fruit of your womb! (Luke 1:40-42)
Blessed Mother, when Elizabeth heard your greeting, the baby leapt in her womb and she rejoiced that the mother of her Savior would come to her. May (NAME) be continuously blessed with your presence in her life, as you rejoice in her joys and comfort her during her struggles.
They were in Bethlehem when the time came for Mary to have her child, and she gave birth to a son, her firstborn. She wrapped him in swaddling clothes and laid him in a manger. (Luke 2:6-7)
Blessed Mother, on the day your son Jesus was born, the heavens were filled with songs of praise. May you protect and strengthen (NAME) as she prepares for the birth of her (SON/DAUGHTER/CHILD) and may she be blessed with a safe and healthy pregnancy and delivery.
When the day came for the purification according to the law of Moses, Mary and Joseph brought the baby Jesus up to Jerusalem to present him to the Lord. Simeon blessed them and said to Mary, “He shall stand as a sign of contradiction, while a sword will pierce your own soul.” (Luke 2:22, 34, 35)
Blessed Mother, in the temple you presented the Child Jesus and trusted that God would guide you in caring for Him and raising Him to live out God’s will. May (NAME) be granted the grace to raise her (SON/DAUGHTER/CHILD) in God’s love so that (HE/SHE) may also love God and desire His will above all else.
When Jesus was twelve years old, he went up to Jerusalem with his parents, according to the custom for the feast. After the festival was over, Mary and Joseph returned, but the boy Jesus remained in Jerusalem and his parents did not know it. On the third day, they found him in the Temple sitting among the teachers, listening to them and asking them questions. (Luke 2:42-43, 46)
Blessed Mother, after finding Jesus in the Temple, you and Joseph returned to your home in Nazareth and lived your lives as a family united in God’s love. May (MOM’S NAME) and (Dad’s NAME) be strengthened in their love for you and each other, so that together they may raise a holy family seeking to live each day with heroic charity.
