"Jesus answered, 'Amen, amen, I say to you, no one can enter the kingdom of God without being born of water and Spirit.'" (John 3:5)
Catholic Sacraments are milestones in our lives, where God reveals to us His great love and especially who He is. Baptism is the First of the Three Sacraments of Initiation in the Catholic Tradition. Confirmation and Holy Eucharist are the other two Sacraments of Initiation. The word baptism in its origins is Greek and means "immersion" and "bath." Immersion in water is a sign of death and emersion out of the water means new life. To bathe in water is also to undergo cleansing. Saint Paul sums up this truth when he says, "You were buried with him in baptism, in which you were also raised with him through faith in the power of God, who raised him from the dead" (Col 2:12).
Catechism of the Catholic Church
"The fruit of Baptism, or baptismal grace, is a rich reality that includes forgiveness of original sin and all personal sins, birth into the new life by which man becomes an adoptive son of the Father, a member of Christ and a temple of the Holy Spirit. By this very fact the person baptized is incorporated into the Church, the Body of Christ, and made a sharer in the priesthood of Christ" (1279)
