About the Monthly Devotion: The Immaculate Conception

December is dedicated to the Immaculate Conception of Mary—the beautiful truth that God preserved Mary free from sin from the very first moment of her life, preparing her to be the mother of Jesus. As we journey through Advent toward Christmas, this devotion invites us to make our own hearts ready and pure to welcome the newborn King.

Family Ideas for December:

• Set up a Nativity scene and add figures as Christmas draws near.

• Light an Advent wreath candle together each week.

• Pray a family Rosary, especially the Joyful Mysteries.

• Do a secret act of kindness to prepare your heart for Jesus.

Bring the December devotion into your mornings. Our Catholic Morning Menu features a beautiful cover and tracing page for each month’s traditional devotion—including December’s devotion to the Immaculate Conception—plus prayers, a Bible memory verse, the liturgical season, and gentle preschool learning to start each day with the faith.

December 3: St. Francis Xavier

Fun Facts:

1. St. Francis Xavier was one of the first Jesuits and a close friend of St. Ignatius of Loyola.

His Story:
St. Francis Xavier was born in Spain in 1506 and became one of the very first Jesuits, alongside his good friend St. Ignatius of Loyola. On fire with love for Jesus, he set sail across the world to share the Gospel, traveling to India, Southeast Asia, and Japan—farther than almost any missionary before him. He baptized many thousands of people and never stopped longing to bring Christ to more. He is honored as the patron saint of all missionaries.

What Kids Can Learn from St. Francis Xavier:
The Good News of Jesus is meant to be shared. We can be “little missionaries” by telling others about God’s love, right where we are.

St. Francis Xavier, you carried the love of Jesus across the world. Help our family to share our faith joyfully with everyone we meet. St. Francis Xavier, pray for us. Amen.

December 6: St. Nicholas of Myra

Fun Facts:

1. St. Nicholas inspired the modern-day Santa Claus.

2. He was known for his generosity, especially to children and the poor.

3. One of his most famous acts was secretly giving dowries to save three sisters from poverty.

Ways to Celebrate:

His Story:
St. Nicholas was a bishop who lived in Myra (in modern-day Turkey) in the 300s. He loved God and was famous for his secret generosity, especially to children and the poor. One beloved story tells how he quietly tossed bags of gold through a window to provide for three poor sisters, saving them from a hard fate. His kindness was so legendary that, centuries later, he inspired the figure of Santa Claus. St. Nicholas shows us that the best gifts are often given quietly, out of love.

What Kids Can Learn from St. Nicholas:
Real giving comes from a loving heart and doesn’t need to be noticed. We can bring Jesus’ love to others through quiet, generous kindness.

A Little Prayer:
St. Nicholas, you gave in secret and cared for the poor. Help our family to be generous and kind, giving joyfully to others as you did. St. Nicholas, pray for us. Amen.

The Story:
In December 1531, the Blessed Mother appeared to a humble man named St. Juan Diego on a hillside in Mexico. She spoke to him tenderly in his own language and asked that a church be built. As a sign, she filled his cloak—called a tilma—with roses in the middle of winter, and when he opened it before the bishop, a miraculous image of Our Lady was found imprinted there. That very image can still be seen today. Our Lady of Guadalupe is the patroness of the Americas and of the unborn, and she reminds us of God’s tender love for every person.

What Kids Can Learn from Our Lady of Guadalupe:
God loves every single person, no matter who they are or where they come from. Mary is a loving mother who always brings us close to Jesus.

Ways to Celebrate:

• Say a prayer asking St. Lucy to help you see God’s light in your life.

Her Story:
St. Lucy was a young girl in Sicily in the early days of the Church, and her name means “light.” She loved Jesus so much that she gave her belongings to the poor and promised her whole life to Him. During a time when Christians were being persecuted, she bravely refused to give up her faith and became a martyr. Because her name means “light,” her feast in the darkest part of winter has become a festival of candles and light in many countries. St. Lucy reminds us that the light of Christ shines even in the darkest times.

What Kids Can Learn from St. Lucy:
Jesus is our light, and we can carry His light to others by being brave and kind. Even in dark or hard times, God’s light never goes out.

A Little Prayer:

He was full of faith and courage, and he preached about Jesus so boldly that some people became angry. St. Stephen became the very first Christian martyr, giving his life for Jesus. Even as it happened, he forgave those who hurt him and asked God to forgive them too, just as Jesus had done on the Cross. His feast comes right after Christmas, reminding us that following Jesus takes both love and courage.

What Kids Can Learn from St. Stephen:
Following Jesus means loving even those who are unkind to us. St. Stephen shows us how to be brave and forgiving, just like Jesus.

A Little Prayer:

John lived a long life sharing the love of Jesus, and he wrote the Gospel of John, three letters, and the Book of Revelation. His symbol is an eagle. St. John teaches us that the very heart of our faith is love.

What Kids Can Learn from St. John:
Jesus wants to be our close friend, just as He was St. John’s. The most important thing of all is to love God and to love one another.

December 29: The Holy Family

1. The Holy Family is Jesus, Mary, and St. Joseph.

2. When Jesus was a baby, the Holy Family traveled to Egypt to keep Him safe.

Ways to Celebrate:

• Look at your Nativity scene and name each member of the Holy Family.

• Do a chore together as a family, the way Jesus helped Mary and Joseph.

• Draw a picture of your family and pray for each person in it.

• Share a special family meal or treat together.

Their Story:
The Holy Family is Jesus, Mary, and St. Joseph. After Jesus was born in Bethlehem, an angel warned Joseph in a dream to take Mary and the baby to Egypt to keep them safe, and Joseph obeyed right away. Later, the Holy Family returned and made their home in the little town of Nazareth. There, Jesus grew up in an ordinary home—helping His mother, learning from Joseph the carpenter, and praying with His family. The Bible tells us that Jesus “advanced in wisdom and age and favor before God and man.” The Holy Family shows every family how to love God and one another.

What Kids Can Learn from the Holy Family:
Jesus chose to grow up in a family, just like ours. Our homes can be holy places when we love, help, and forgive one another.

A Little Prayer:
Jesus, Mary, and Joseph, you loved one another and made your home a place of prayer. Bless our family and help us to be kind, patient, and loving with each other. Holy Family, pray for us. Amen.
