Unfortunately in many parishes RCIA is kind of the catch all class for any adult who doesn’t have all (or any) of their sacraments. When I came into the Church, my RCIA class was made up mostly of confirmands (people who had never been confirmed for one reason or another, but were Cradle Catholics). There were some who had never been to any church ever. That’s the group RCIA is supposed to be for. Or for people who have been baptized in another Christian faith as children, but again, for all intents and purposes are unchurched. In other words, RCIA is for people who know next to nothing about God, and even less about the Catholic Church. The purpose is two-fold. First, and most importantly is to introduce them to Faith: to God so that when they are baptized they have a relationship with the One who is taking away their sins. And second, to know at least the basics of Church teaching.
In my case, I came from a Protestant Tradition where I had been “saved” at 8, baptized at 12, been in church all of my life, involved in various ministries and had studied to be a pastor at one point in time. RCIA was not a good fit for me, because my questions - and I had a lot - were extremely different from the questions of the rest of the class. I was the kind of Candidate a lot of RCIA programs don’t quite know what to do with. Perhaps because most RCIA programs don’t have enough people helping out. When there is only one person teaching, dividing out the different needs gets tricky. To me, RCIA was a “hoop” I had to jump through in order to receive the Eucharist. Part of that view was re-enforced by the fact that while a Candidate I was asked to lead discussion groups and lead Breaking Open of the Word a time or two (I clearly remember once, might have been twice). Which were things that a non-Catholic shouldn’t be doing. I couldn’t understand why I was “Catholic” enough to teach others, but not “Catholic” enough to receive the Eucharist. It was a lesson in patience, obedience (even when extremely hard) and humility. And God did shower me with many graces during that time, so now I am grateful things worked out as they did. But then…not so much.
