Rite of Christian Initiation of Adults
What is the RCIA?
The Rite of Christian Initiation of Adults (RCIA) is the process by which people become members of the Roman Catholic Church. The process is concerned with the total formation of the person into
- Believing with the Church community (doctrinal formation)
- Living with the Church community (practical formation)
- Praying with the Church community (liturgical formation)
- Serving with the Church community (apostolic formation)
This gradual development culminates in the celebration of the initiation sacraments of Baptism, Confirmation and the Eucharist at the Easter Vigil.
Who may participate in the RCIA?
The Rite is designed primarily for those seeking Baptism; that is those not baptized previously. However, because of the nature of conversion as an ongoing reality, the RCIA can be adapted for those baptized in other Christian denominations, now seeking membership in the Roman Catholic Church. At Corpus Christi Parish, adults baptized in the Catholic faith but not confirmed are also welcomed through the RCIA process.
What are the basic principles of the RCIA?
The principles deduced from the early Church initiation practice, are the basic guidelines from which the RCIA has been created.
- The core reality of Christian initiation is conversion.
- The gradual movement towards Christian initiation is a
process and not a program. - A close relationship exists between catechesis and liturgy
- The initiation of new members is the concern and
responsibility of the entire community. - The primary subject of the process is the adult.
- The Word of God is central to the formation process.
- The truths of the Christian faith are unfolded through the
experience of the Church’s dominant symbols.

The Biblical Institute of the Diocese of Joliet
The Biblical Institute of the Diocese of Joliet is a 4-year program to study every book of the Bible. We use one of the best Catholic Bible studies ever developed for learning Scripture in a systematic way, the Catholic Biblical School Program (Paulist Press). Students earn certificates in Basic Biblical Studies (2 years) and Advanced Biblical Studies (4 years), from this nationally recognized program..
Try the first two years (Old Testament and New Testament Foundations) and decide later whether to stay for Years 3 and 4 (the rest of the Bible).
The Biblical Institute is for everyone! Some of our students serve their parishes as catechists, lectors, or Bible study facilitators. Many people join us with no Bible study background at all. If you bring a commitment to learning and a desire for deeper understanding of God’s Word, we’ll give you what you need to successfully participate in the program. We also welcome interested fellow Christians, so mention us to neighbors and friends!
You’ll study the Bible as a whole and in its parts from a Catholic point of view, with experienced teachers, and within a Catholic faith community.
If you have questions, please call the Diocese of Joliet Religious Education office at 815-221-6147.

I. New Evangelization
Course Description: Jesus reveals the self-giving and self-sacrificing love of God, and he calls his disciples to bring the good news of the Kingdom of God to the entire world. The new evangelization is an invitation to hear this good news of the Gospel again, as if for the first time; it is a call to re-encounter the living Lord in and through the Church. This course will help participants continue to answer their personal call to holiness, to explore the responsibility of all baptized Catholics to spread the Good News, and to contribute to the Church’s mission of bringing all people to Christ.
Session One: Disciples Called to Witness
Session Two: Sharing the Joy of the Gospel
II. Methods of Faith Formation
Course Description: Teaching the faith in a systematic and organic way requires that catechists imitate the way that God draws us to Himself—that is, by preparing the setting and audience for an encounter with Christ, by proclaiming the truth to be examined, by explaining this “good news” in greater depth, and by relating it to everyday life.
Session One: Understanding Students & Leading them to Christ
Session Two: Planning an Engaging Catechetical Session
III. Creed
Course Description: The Creed summarizes the most fundamental truths of our faith which have been handed down to us from Christ, in and through the Church. By beginning to unpack the fundamental doctrines of Chrisianity, this course helps participants continue to grow in understanding of both the Triune God of Love and the call to build the Kingdom of God.
Session One: I Believe in God the Father
Session Two: I Believe in Jesus Christ
Session Three: I Believe in the Holy Spirit
IV. Sacraments
Course Description: The mysteries professed in the Creed are communicated and actualized in the Sacraments of the Church. By providing participants with a deeper understanding of the divine origin, nature and central role of the Sacraments, this course will help participants grow in understanding of their role in the sacramental mission of the Church.
Session One: The Sacramental Economy
Session Two: The Sacraments of Initiation
Session Three: The Sacraments of Healing
Session Four: The Sacraments of Service
V. Moral Life
Course Description: To be a Christian is a matter not only of believing in Jesus but, as St. Paul describes it, of living in Christ so that “I live, no longer I, but Christ lives in me”
(Gal 2:20). What the Creed professes and the Sacraments communicate, the Christian moral life enacts—thanks to the grace of Christ and the gifts of the Holy Spirit. This course explores Christian moral principles by beginning with the dignity and vocation of the human person created in the image and likeness of God; it addresses key concepts such as freedom, responsibility, moral conscience, virtue and vice, law and grace, and the Beatitudes; it concludes with an overview of the Ten Commandments as the basis of our moral life in Christ.
Session One: The Vocation of the Human Person
Session Two: The Commandments—Love of God
Session Three: The Commandments—Love of Neighbor

VI. Christian Prayer
Course Description: Prayer is the loving communication between the human person and the living and true God. “Prayer is Christian insofar as it is communion with Christ nd extends throughout the Church, which is his Body,” explains the Catechism: “Its dimensions are those of Christ’s love” (CCC, n. 2565). This course will explore the universal call to prayer, which is written in our hearts by our Creator, as well as the various expressions of prayer, and the greatest of all prayers—the Our Father. The course will also model various approaches to Catholic prayer.
Session One: Prayer in the Christian Life
Session Two: The Lord’s Prayer–The “Our Father”
