RCIA is mostly definitely for those who have received the Sacraments of Baptism & Eucharist, but have never received Comfirmation.
Have you read the Rite book itself? The Rite tells you who the Rite is for. The Rite does allow for baptized
unchatechized Catholics.
Those who were
catechized but did not get confirmed have an adult confirmation process that is not RCIA.
It is also a tool for those Catholics who have received the Sacraments of Baptism, Eucharist & Confirmation for a seeking a better understanding of there Catholic faith.
Again the Rite book tells you who the Rites are for. They are
not for fully initiated Catholics.
The catechesis portion of RCIA is not RCIA, only one part of it. Group catechesis for those receiving the Rites is common.
While it may also be a practice where you live to allow anyone to come to the catechesis nights, RCIA is not “for” adults who have already received the sacraments of initiation.
There are many reasons that the practice of commingling RCIA catechesis and Catholic adult education together is harmful to the catechumens and candidates for full communion.
In most places this is discouraged or not allowed.
I was on the RCIA team for 10 years before I moved and I am the RCIA Director where I am now. You have also spoken disrespectfully to a priest on this site— a priest who does in fact know what he is taking about.
Tawny, there is no shame in being wrong. But you are in fact wrong on this.
