The Order of Christian Initiation of Adults (OCIA) is the process established for the universal Church for individuals to become Catholic and receive the sacraments of initiation - Baptism, Confirmation, and the Eucharist. The Rite speaks of conversion as a "spiritual journey." Centered on fostering a deep relationship with Jesus and the Church he founded, this journey takes place through distinct stages over a period of time suitable to bring about a thorough catechesis, significant experience of the parish community, and commitment to the liturgical and moral life of the Catholic faithful. The RCIA process is a restoration of the ancient catechumenate, arising within the first three centuries following the era of the apostles. It was the early Church's way of Christianizing the pagan Roman Empire. The Second Vatican Council called for the restoration and use of this venerable and powerful method of initiation for the worldwide Church.
