Conversion is a gradual process.

The RCIA as a rite, marks stages along the path to full commitment in the Roman Catholic Church; the RCIA as a process, describes in broad terms what this gradual commitment means.

The RCIA as formation gradually looks to the inner transformation of the individual to God's call as given week by week in the lectionary of Scripture readings. It also looks to Sunday Eucharist and to the gradual transformation of the person to become an active member of the local church wherever he or she lives.
