“And Jesus came and said to them, ‘All authority in heaven and on earth has been given to me. Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything that I have commanded you. And remember, I am with you always, to the end of the age.’"
Matthew 28: 18-20
“ Baptism is the sacrament of rebirth as a child of God sanctified by the Spirit, of unity with Jesus in his death and resurrection, of cleansing from original sin and personal sins, and of welcome into the community of the Church.”
(General Catechetical Directory, par. 11)
“ … the faithful who by Baptism are incorporated into Christ, are placed in the People of God, and in their own way share the priestly, prophetic and kingly office of Christ, and to the best of their ability carry on the mission of the whole Christian people in the Church and in the world. …
There is, therefore, one chosen people of God: ‘one Lord, one faith, one Baptism’ (Eph. 4;5) there is a common dignity of members deriving from the rebirth in Christ, a common grace as sons, a common vocation to perfection, one salvation, one hope and undivided charity.”
(Lumen Gentium, Dogmatic Constitution on the Church, paragraphs 31. 32.)
The sacramental celebrations are key events in the lives of Christians. These sacramental moments therefore, require adequate preparation and follow through. People can receive Baptism at different ages. Accordingly the process of Baptism preparation is different for each age group.
