Below is a quote from the Catechism of the Catholic Church on the doctrine of justification. Note that the Catholic doctrine of justification is understood as “the acceptance of God’s righteousness” (not our own) and that it relates to “divine love.” It also leads to “obedience.”

“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.” (Catechism of the Catholic Church, no. 1991)
