Catholic Catechism:
1991
Justification is at
the same time the
acceptance
of God's righteousness through faith in Jesus Christ. Righteousness
(or "justice") here means the rectitude of
divine love. With
justification, faith, hope, and charity are poured into
our hearts,
and obedience to the divine will is granted us.
2019
Justification
includes the remission of sins, sanctification,
and the renewal of the inner man.
2018
Like conversion,
justification has two aspects. Moved by
grace, man turns toward God and away from sin, and so
accepts
forgiveness and righteousness from on high.
Council of Trent’s teaching:
Canon
X If any one says, that by faith alone
the impious is justified; in such wise as to mean, that
nothing else
is required to co-operate in order to the obtaining the
grace of
Justification, and that it is not in any way necessary,
that he be
prepared and disposed by the movement of his own will;
let him
be anathema.
