Catechism of the Catholic Church

1265 Baptism not only purifies from all sins, but also makes the neophyte "a new creature," an adopted son of God, who has become a "partaker of the divine nature," ⁶⁹ member of Christ and co-heir with him, ⁷⁰ and a temple of the Holy Spirit. ⁷¹

1266 The Most Holy Trinity gives the baptized sanctifying grace, the grace of justification:

- enabling them to believe in God, to hope in him, and to love him through the theological virtues;

- giving them the power to live and act under the prompting of the Holy Spirit through the gifts of the Holy Spirit;

- allowing them to grow in goodness through the moral virtues.

Thus the whole organism of the Christian's supernatural life has its roots in Baptism.
