One would still need to be catechized before being allowed to receive the other Sacraments. Although technically being baptized means you can go to confession, receive anointing, receive the Eucharist and receive Confirmation. You need to be confirmed before you can get married or getting Ordained.
You are correct. Anyone that is baptized in a Catholic Church with documentation is not doubt already Catholic. They still need to be catechized, but in light of this the candidate is now no longer a candidate but a Catholic in need of confirmation. Thus, that person can approach the priest and request that they immediately be allowed to begin receiving first communion even before confirmation.
Congratulations. Don’t take not now or no as an answer. The priest has an obligation to you along this line. Since you are already in RCIA you can continue for confirmation, but since you’ve probably already covered the Eucharist you should have no problem being able to receive. Just make it clear to the priest that you want to begin receiving immediately. Don’t take no for an answer. He does not have the right to hold you from it, that is if you have been brought up to speed by this time. I only went to 7 classes to be able to take it. I went one on one with the priest in my parish.
Oh, you are eligible to receive all of the sacraments with the exception of holy orders. And if you are not male then that won’t make any difference. Just do it correctly by addressing this with your pastor first. It’s respectful and proper. Don’t suddenly let it go to your head. That’s not a proper position to take.
Confirmation is not required or at least used to not be required. My wife was in RCIA when we had our marriage convalidated. But that was to correct a lack of form to make it possible for us to act as husband and wife again and legitimize our children.
Technically, all of them, you receive your First Communion before Confirmation, as well as your first Confession, so as long as the OP goes to confession, they have no reason to abstain from Communion, as technically, they are in full communion with Rome by virtue of there Baptism.
As far as I know, all thats required to receive Communion is to be a Baptized Catholic, I had to abstain during my Conversion as technically I was Anglican in the eyes of the Church by virtue of my Baptism, however another Candidate with me in RCIA was baptized Catholic, they was required to receive the Sacrament of Reconciliation, and they could receive the Body and Blood of our Lord in the Eucharist.
