Catechesis of the Good Shepherd

 “I am the good shepherd; I know my sheep and my sheep know me— just as the Father knows me and I know the Father—and I lay down my life for the sheep.” John 10:14

A Brief introduction to CGS

The Catechesis of the Good Shepherd is a religious education program designed for young children, typically ages 3 to 12. Developed by Sofia Cavalletti and Gianna Gobbi in the 1950s, it is rooted in the Montessori method and emphasizes a child-centered approach to spiritual formation.

The program focuses on helping children develop a deep, personal relationship with God through a carefully prepared environment called the "Atrium." In this space, children engage with hands-on materials and presentations that reflect key aspects of the Christian faith, such as the life of Jesus, the Sacraments, and the liturgy.

The Catechesis of the Good Shepherd encourages children to explore their faith through sensory experiences and meaningful, age-appropriate activities. It aims to nurture their spiritual growth in a way that respects their natural development and curiosity, allowing them to discover and connect with the sacred mysteries of the Christian tradition in a way that resonates with their own experiences and understanding.

St. Anne Atrium

Divine Mercy Academy is proud to offer Catechesis of the Good Shepherd for our students in preschool - kindergarten. Our dedicated catechists are trained using a Montessori approach to help children develop their existing relationship with our Creator.

Students enter an intentionally prepared and peaceful environment, called an atrium, where they hear Scripture, rejoice in song, ponder God’s nature, are introduced to the sacraments, and even practice important development practical skills such as pouring water and tidying up.

Our youngest students will spend on average an hour and a half each week in the atrium, accompanied by trained catechists and assistants.

We are in the process of building a Level II atrium, which will be open to first and second graders for the 2025/2026 school year. Volunteers are needed to build materials as well as work in the atrium. Please contact cgs@dmamt.org if you can help!

  • St. Anne Atrium was established in collaboration with St. John Vianney Parish and with the help of many in our community who devoted countless hours of their time and talents in the making and acquiring of materials. Its founding has been a true labor of love.

    Our chosen patroness, St. Anne, is venerated as the mother of the Blessed Virgin Mary. She was a pious and faithful woman who raised Mary with grace and selflessly entrusted her to God. St. Anne is a powerful intercessor for all who are dedicated to raising children in the faith.

  • We have an excellent group of trained catechists who lead and assist in our atria sessions.

    If you are interested in joining our team of volunteers at St. Anne Atrium or would like to learn more about CGS, please contact our program director at cgs@dmamt.org.

    For catechist training opportunities in the Diocese of Helena, please see the diocesan website HERE.

    While formation through CGSUSA is required to be a catechist, there are other ways to help in the atrium that do not require training, including as an assistant.

"The initiation of a child into Christian life is not a work that can be fulfilled by the catechist alone, nor by the parents alone. It is the whole Christian community that proclaims Christ, and the child must enter into contact with the entire Christian community" 

- Sofia Cavalletti (co-founder of CGS)
