VI. The Necessity of Baptism

From The Catechism of the Catholic Church

1257
The Lord himself affirms that Baptism is necessary for salvation.⁵⁹ He
also commands his disciples to proclaim the Gospel to all nations and to
baptize them.⁶⁰ 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.⁶¹ 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.
