Download and read the PDF article titled: Preparing to Receive the Life of God: RCIA Catechesis in the Period of Purification and Enlightenment to learn about how catechesis changes when you exit the period of the Catechumenate and enter the period of Purification and Enlightenment.
A quote from the above article:
“During the period of purification and enlightenment, the focus becomes a stronger emphasis on the spiritual and mystical life in preparation for the sacraments. The guidelines for this period (which normally coincides with Lent) as well as the rites associated with them, enable catechists to shift the focus of teaching from an exposition of the Deposit of Faith to reflection and meditation. Before they receive the sacraments of initiation, ‘the elect must have the intention of achieving an intimate knowledge of Christ and His Church, and they are expected particularly to progress in genuine self-knowledge through serious examination of their lives and true repentance.’”
