Catholic Catechism:
2019 Justification includes the remission of sins, sanctification,
and the renewal of the inner man.
 1995 The Holy Spirit is the master of the interior life. By giving
birth to the "inner man," justification entails the sanctification of
his whole being: Just as you once yielded your members to
impurity and to greater and greater iniquity, so now yield your
members to righteousness for sanctification. . . . But now that you
have been set free from sin and have become slaves of God,
the return you get is sanctification and its end, eternal life (Romans
6:19,22).
