VII. The Grace of Baptism

From The Catechism of the Catholic Church

1272
Incorporated into Christ by Baptism, the person baptized is configured to
Christ. Baptism seals the Christian with the indelible spiritual mark
(character) of his belonging to Christ. No sin can erase this mark, even if sin
prevents Baptism from bearing the fruits of salvation.⁸² Given once for
all, Baptism cannot be repeated.
