The process is for adults who are unbaptized or adults baptized in another Christian denomination. There are four stages to the process:

• Precatechumenate: it is a time to introduce the person of Jesus Christ, the Gospel message and values, and an opportunity to grow in faith.
• Catechumenate: this time nurtures the person as he or she grows in understanding of the faith and for continued conversion to God.
• Purification and Enlightment: this is usually during the Season of Lent and allows for greater reflection and a deepening of the spiritual life.
• Mystagogy: this takes place during the Easter Season to experience full integration to the Christian community with continued formation.
