The Catechism of the Catholic Church is a complete summary of all that the Catholic Church teaches and believes.
This is the full catechism. For younger readers, consider YOUCAT – Youth Catechism instead.
The Catechism references the Bible, the parts of the Mass, the Sacraments of the Church, the Apostolic Tradition, and the insights of the saints to explain the teachings of the Catholic Church. The references provide a way to study the beliefs which Catholics hold and come to a deeper understanding.
The Catechism will help you find answers about Catholic teachings and will help you understand and explain the faith to others.
