How to Convert or become a Catholic: Step by Step Process

The decision to become a Catholic is a profound and life-changing one, representing a personal and spiritual journey of exploration, learning, and commitment. Whether you are new to Christianity or transitioning from another Christian denomination, the process of becoming a Catholic involves a deliberate and intentional embrace of the teachings, sacraments, and traditions of the Catholic Church. This in-depth article aims to provide a comprehensive and detailed guide, elucidating each step involved in becoming a Catholic and the significance of these steps within the broader context of the Catholic faith.

Step 1: Initial Inquiry and Exploration

The journey to becoming a Catholic often begins with a spark of curiosity or a genuine desire to explore the Catholic faith. During this initial phase, individuals may attend Mass, visit Catholic churches, and participate in various community events to get a feel for Catholic practices and beliefs. Engaging in open conversations with practicing Catholics and seeking guidance from a parish priest can provide valuable insights and answers to questions that arise during this period of exploration.

Step 2: Rite of Christian Initiation for Adults (RCIA)

The Rite of Christian Initiation for Adults (RCIA) is the formal process designed for individuals seeking to become Catholics. It is a time of formation, instruction, and spiritual preparation for those entering the Catholic Church. RCIA programs vary from parish to parish, but they typically consist of a series of classes, discussions, and spiritual formation sessions led by clergy members, catechists, and experienced Catholics.

The RCIA process generally lasts several months, allowing candidates to progress at their own pace. These sessions delve into the foundational beliefs of Catholicism, explore the Bible and its significance in the faith, delve into the sacraments and their role in Catholic life, introduce various forms of prayer and spirituality, and uncover the rich history and traditions of the Catholic Church.

Beyond the intellectual and educational aspects, the RCIA process also facilitates the building of a sense of community among the participants and their relationship with the wider parish community. Candidates form bonds with fellow participants and share their experiences and insights, fostering mutual support and encouragement as they embark on this transformative journey.

Step 3: Rite of Acceptance into the Order of Catechumens

As candidates progress through the RCIA process and demonstrate a sincere desire to become Catholics, they take part in the Rite of Acceptance into the Order of Catechumens. This formal ceremony marks a significant milestone in the journey, as candidates publicly declare their intention to join the Catholic Church, and the Church, in turn, formally accepts them as catechumens.

The term “catechumen” describes those preparing for Baptism, a sacrament that symbolizes spiritual rebirth and incorporation into the body of Christ—the Church. By entering the Order of Catechumens, individuals are recognized as members of the Church community, albeit not yet fully initiated.

Step 4: Sacraments of Initiation

The Sacraments of Initiation—Baptism, Confirmation, and Eucharist—play a central role in the process of becoming a Catholic. These sacraments are viewed as transformative encounters with God’s grace and serve as the foundation for the candidate’s lifelong commitment to the Catholic faith.

  1. Baptism: For individuals who have not previously received Christian Baptism, this sacrament is the first step. During the Baptismal ceremony, candidates are cleansed of original sin and are born anew in Christ. Water, a symbol of purification and renewal, is poured over the candidate’s head or they are immersed in it, accompanied by specific prayers and blessings.
  2. Confirmation: Following Baptism, candidates receive the Sacrament of Confirmation. This sacrament completes the process of initiation and is often administered by a bishop or a priest delegated by the bishop. During Confirmation, the Holy Spirit strengthens and empowers the newly baptized, equipping them with the gifts and graces necessary to live out their faith courageously and faithfully.
  3. Eucharist: The final sacrament of initiation is the Sacrament of the Eucharist, also known as Holy Communion. In this sacrament, the newly baptized participate in the body and blood of Christ, represented by bread and wine. This intimate encounter with Christ in the Eucharist is a deeply profound and central aspect of Catholic worship and spiritual life.

These Sacraments of Initiation are often celebrated together during the Easter Vigil—a significant liturgical event in the Catholic Church that takes place on Holy Saturday night, leading to Easter Sunday.

Step 5: Mystagogia

After receiving the Sacraments of Initiation, new Catholics enter a period known as “Mystagogia.” This phase marks the final stage of the formal initiation process and extends beyond the Easter season, typically lasting several weeks or even months. The term “Mystagogia” derives from the Greek word “mystagogos,” meaning “one who leads into the mysteries.” During this time, candidates and newly initiated Catholics delve deeper into the mysteries of the faith they have encountered in the sacraments.

Mystagogia involves ongoing formation, reflection, and support as new Catholics begin to integrate fully into the life of the Catholic Church. It is a time for the candidates to deepen their understanding of the sacraments they have received, explore various forms of Catholic prayer and spirituality, and discern how they can contribute to the Church and the wider community through their unique gifts and talents.

Throughout this period, candidates are encouraged to participate actively in the parish community, attending Mass regularly, engaging in parish activities, and building relationships with fellow parishioners. The parish community plays a vital role in supporting new Catholics as they navigate the initial stages of their faith journey and find their place within the larger Church family.


Becoming a Catholic is an enriching and transformative journey that involves an initial phase of inquiry and exploration, followed by a formal period of preparation through the Rite of Christian Initiation for Adults (RCIA). The RCIA process is designed to provide candidates with a comprehensive understanding of the Catholic faith, introducing them to its beliefs, practices, and traditions.

The reception of the Sacraments of Initiation—Baptism, Confirmation, and Eucharist—represents the pinnacle of the journey, as candidates are fully incorporated into the body of Christ—the Church. These sacraments mark the beginning of a lifelong commitment to grow in faith, love, and service to God and others.

Following their initiation, new Catholics enter the phase of Mystagogia, where they continue to deepen their understanding of the faith, explore various forms of prayer and spirituality, and discern their role within the Church community.

Throughout this journey, the support of the parish community, clergy members, and fellow participants in the RCIA program is of paramount importance. The process of becoming a Catholic is not merely a series of rituals, but a transformative and lifelong commitment to walk in the footsteps of Christ and to live out the teachings of love, compassion, and service to the world. As new Catholics, they become part of a global and diverse community united in faith and the pursuit of spiritual growth and fulfillment.
