So my wife and I, each baptized, are in RCIA right now. I have a question. If we complete the RCIA course, express desire to be confirmed and received into full communion, is there a chance we will be told “no?”
rule #1 about RCIA-do not compare your experience with that of anyone else in your group, or that you have known or read about. You don’t know where they started, how long they have been on the journey, and what hurdles they have faced in their conversion, and they do not know your story. Worry only about your own journey and take the guidance that is being offered to you.
No, you will not be told NO unless there is some barrier that still exists which would prevent you from coming into full communion with the Church. Most often that is a problem related to marriage or “lifestyle choices.” You cannot receive confirmation and first communion if you are objectively living in a state of mortal sin, nor could a catechumen be baptized if they insist on remaining in a living situation which would place them immediately in a condition of mortal sin.
These are pastoral issues that the candidate should be working through with the help of the priest, and are beyond the competence of most lay persons working in RCIA as catechists, director or team member. You should have had the opportunity for one (or more) interviews with the pastor or his delegate at the beginning of the process, and during the RCIA journey as needed, so there should be no surprises.
If you have issues, make an appointment and speak to the priest about it now.
The other reason that commonly holds people back, besides unreadiness for conversion, is a misunderstanding or inability to accept Church doctrine on some points, and that calls for more prayer first of all, and more study, and often more time, so yes they might agree, after speaking with catechist, sponsor and pastor, on their own assessment that they do not feel ready to make a profession of faith at this time.
But no, if someone arbitrarily tells you NO, you need to speak to the pastor immediately, or to the bishop if the pastor does not give you enough information.
