The Most Important Event of Your Life (Baptism of the Lord-19)
Baptism and Salvation in the Catechism of the Catholic Church (CCC)
CCC161: Believing in Jesus Christ and in the One who sent him for our salvation is necessary for obtaining that salvation. “Since without faith it is impossible to please [God]’ and to attain to the fellowship of his sons, therefore without faith no one has ever attained justification, nor will anyone obtain eternal life but he who endures to the end.'”
CCC1257: The Lord himself affirms that Baptism is necessary for salvation. He also commands his disciples to proclaim the Gospel to all nations and to baptize them. Baptism is necessary for salvation for those to whom the Gospel has been proclaimed and who have had the possibility of asking for this sacrament. The Church does not know of any means other than Baptism that assures entry into eternal beatitude; this is why she takes care not to neglect the mission she has received from the Lord to see that all who can be baptized are “reborn of water and the Spirit.” God has bound salvation to the sacrament of Baptism, but he himself is not bound by his sacraments.
CCC1129: The Church affirms that for believers the sacraments of the New Covenant are necessary for salvation. “Sacramental grace” is the grace of the Holy Spirit, given by Christ and proper to each sacrament. The Spirit heals and transforms those who receive him by conforming them to the Son of God. The fruit of the sacramental life is that the Spirit of adoption makes the faithful partakers in the divine nature by uniting them in a living union with the only Son, the Savior.
CCC265: By the grace of Baptism “in the name of the Father and of the Son and of the Holy Spirit,” we are called to share in the life of the Blessed Trinity, here on earth in the obscurity of faith, and after death in eternal light.
