We move to the next rite, the one fully titled, “Rite of Calling the Candidates to Continuing Conversion.”
The corollary for catechumens is the Rite of Election. But the baptized are already members of the Elect.
RCIA provides four brief sections of instruction before getting to the rubrics and ritual. Here they are:
446. This rite may be celebrated with baptized but previously uncatechized adults who wish to complete their Christian initiation through the sacraments of confirmation and eucharist or who wish to be received into the full communion of the Catholic Church
447. The rite is intended for celebrations in communities where there are no catechumens.
448. The rite is celebrated at the beginning of Lent. The presiding celebrant is the pastor of the parish.
449. If the calling of candidates to continuing conversion is to be combined with the rite of election of catechumens (either in a parish celebration or at one in which the bishop is celebrant) the alternate rite given [in RCIA 550-561] (Appendix I, 3) is used.
Some logical points. First, it would be extremely unusual for a bishop to receive candidates and no catechumens at the beginning of Lent. This rite is not celebrated in the cathedral, but in the parish. If there are candidates to be sent to the bishop (RCIA 434-445) without catechumens, they will probably be part of a larger combined celebration (RCIA 550ff).
