Baptism, Confirmation, and Eucharist are the sacraments by which we become full members of the Church, the body of Christ and complete Christian initiation. They provide the foundation for the other sacraments and usher the individual into the heart of the Church.
Baptism is the Sacrament of regeneration and initiation into the church that was begun by Jesus, who accepted baptism from St. John the Baptist and also ordered the Apostles to baptize in the Father, the Son and the Holy Spirit. (Matthew 28:19)
