422. What is justification?
Justification is the most excellent work of God's love. It is the merciful and freely-given act of God which takes away our sins and makes us just and holy in our whole being. It is brought about by means of the grace of the Holy Spirit which has been merited for us by the passion of Christ and is given to us in Baptism. Justification is the beginning of the free response of man, that is, faith in Christ and of cooperation with the grace of the Holy Spirit.

423. What is the grace that justifies?
That grace is the gratuitous gift that God gives us to make us participants in his trinitarian life and able to act by his love. It is called habitual, sanctifying or deifying grace because it sanctifies and divinizes us. It is supernatural because it depends entirely on God's gratuitous initiative and surpasses the abilities of the intellect and the powers of human beings. It therefore escapes our experience.
