OCIA is a process of study, exploration, faith-sharing, and faith formation with specific liturgical rites for seekers and inquirers. Seekers and inquirers are non-baptized adults who desire to be fully initiated into the Roman Catholic Church and/or baptized adult Christians who desire full communion in the Roman Catholic Church.  Adults or older children who were baptized in another Christian denomination prepare in a similar way for the sacraments of Confirmation and the Eucharist during their reception into the Catholic Church.
