The Catholic Defender: For a Protestant person to convert to the Catholic Faith, they become a fullfilled Christian

Entering the Catholic Church from a Protestant background involves entering into the full communion of the Catholic faith rather than starting over from scratch.

 The Catholic Church recognizes most Protestant baptisms as valid if they used water and the Trinitarian formula ("in the name of the Father, and of the Son, and of the Holy Spirit"). Validly baptized Protestants are not rebaptized. 

Profession of Faith: Converts make a formal profession of faith by reciting the Nicene Creed and accepting the teachings of the Catholic Church.

 Candidates normally receive the Sacrament of Confirmation and make their first Holy Communion during a special Mass, completing their initiation into full communion. 

Preparation (OCIA): Most inquirers attend the Order of Christian Initiation of Adults (formerly RCIA) classes at a local parish to study Scripture, Church history, and theology before being received.

The Eucharist: Many converts point to a deep realization of the Real Presence of Christ in the Eucharist, often connecting it to a literal reading of John 6.

 Others seek the historical continuity, apostolic succession, and unified teaching authority of the Catholic Church rather than the individual interpretation of Scripture found in many Protestant denominations.
