The United States Catholic Conference of Bishops states,

• Catechesis is the act of handing on the Word of God intended to inform the faith community and candidates for initiation into the Church about the teachings of Christ, transmitted by the Apostles to the Church.
• Catechesis also involves the lifelong effort of forming people into witnesses to Christ and opening their hearts to the spiritual transformation given by the Holy Spirit. 

Why is it important for us to learn about our faith?
 
   Because we need to build a relationship with Jesus. And the best way to get to know someone is to learn about them. Jesus wants to have a relationship with each one of us. The best way to get to know Jesus is by going to Mass and studying outside of Mass. That is why Faith Formation (Religious Education) is so important in every stage of life -- Adult, Children, and Youth.
