"A new creature"
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.
