I was baptized Catholic as an infant. Ive been a Christian my whole life.
I have received the Sacrament of Marriage and both of my children are baptized Catholics.
As an adult, I am ready to receive the Sacrament of Penance and the Sacrament of Holy First Communion. Why is my parish requiring I go thru RCIA?

Im not trying to rush through the process, but am curious why this is a requirement?
Thanks
they aren’t requiring you to go to RCIA, they are being sloppy about terminology. The acronym means Rites of Christian Initiation for Adults, and there is a provision for including baptized but uncatechized Catholic adults (or children over the age of reason). But just as with baptized non-Catholic Christians, these are called “candidates” because they are candidates for confirmation and first communion. There are optional rites for them to punctuate the transitions on their faith journey.
The catechumens are the unbaptized and the rites celebrated for them during their preparation are based on that fact and that the character of their conversion is different.
Most parishes for all practical purposes include all adults who need initiation sacraments in one class for the doctrine instruction and separate the two groups only for the rites themselves, and since RCIA is easier to say than “confirmation class for Catholic adults” we get in the habit of calling all adult sacramental classes “RCIA”.
In this diocese priests who initiated new Christians at Easter are specifically excluded from confirming previously baptized Catholic adults. They are supposed to be confirmed (and make first communion, preceded by confession at the same time if they need it) either when the bishop visits the parish to confirm youth, or in the one large diocesan celebration at Pentecost.
Why not simply ask the director or catechist of your program, for one good reason, to make sure they understand your status and your particular needs.
I used to try and keep catechumens, non-Catholic baptized candidates, and Catholic adults in need of confirmation in separate classes, but found they all essentially need the same instruction so for most of the preparation they are in the same doctrine class. This time of year, just before and during Lent and Easter, we separate the catechumens for their specific rites and preparation. We found it a better use of resources and the time and talent of catechists to separate groups on the basis of age, child, youth or adult, and language, Spanish or English.
