Baptism is the first mystery of Christian Initiation. It initiates new members into the Body of the Church. Our Lord's instruction to His disciples was "Go and teach all nations, baptizing them in the Name of the Father, Son, and Holy Spirit". Once one enters into the Kingdom of God, they must be reborn of water and spirit in order to truly experience it.

The second mystery of Christian initiation is Chrismation. Through this sacrament, the newly baptized receives “The Seal of the Gift of the Holy Spirit.” Just as the apostles received it at Pentecost, the one anointed by Chrism receives the coming of the Holy Spirit.

Holy Eucharist is the third mystery of Christian initiation. The newly baptized, nourished by Christ and filled with the Holy Spirit, receives the Body and Blood of Christ as sustenance. While Baptism and Chrismation are received once, Holy Communion is received throughout one's life because in and through this Mystery, the Christian grows in grace received in Baptism and Chrismation.

The Holy Mystery of Repentance also known as Confession is one of two ways that Christ can heal us. In our human weakness, we sin. By accepting Christ's forgiveness, He can make us whole again. Repentance and Confession are the way that He comes to us
