Through such an expansion of the abbreviated rite a new candidate can reach the same level as those who are already advanced in the catechumenate, since some of the earlier elements from the full rite can be added, for example, the rite of acceptance into the order of catechumens (RCIA 48-74) or the minor exorcisms (no. 94) and blessings (no. 97) from the period of the catechumenate. The expansion also makes it possible for a candidate who had begun the catechumenate with others, but was forced to interrupt it, to complete the catechumenate alone by celebrating, in addition to the sacraments of initiation (see nos. 206-217), elements from the full rite, for example, the rite of election (see nos. 118-128) and rites belonging to the period of purification and enlightenment (see nos. 141-159).
In other words, the initiation rite can be augmented by pretty much anything the candidate for baptism has missed.
