Rebuttal: Catholics understand that judgement is upon us all
What the Church Teaches
What the Bible Says
In Other Words
A Catholic who understands the faith knows he / she is not good enough when standing on their own. We are fallen humans, at best. But a person is good by his super natural nature, since man is created in God’s image and likeness. Therefore, the one who accepts God's grace, through the works of the Holy Spirit, is justified by the merit of Christ through His Passion and Cross.
Typically, the problem here is that non-Catholics believe that they themselves have authoritative understanding of authentic doctrines and theologies of the Church. It is clear to me, they do not. In the 25 years of my personal Catholic journey, hearing many talks, witnessing many Masses, I have never heard a priest or bishop tell the congregation to go out and perform good deeds in order to earn our salvation. CCC 418 as quoted above is one example of Catholic teaching. The Catholic Church does NOT teach that we are good enough to get into heaven. We, on our own, are NOT good enough. We must rely on God's sanctifying grace.
The Catholic Church teaches that without God’s grace and mercy humans are separated from God’s divine life. If one does consider himself to be "good enough," even by a single act of accepting Jesus as their personal Lord a Savior, there would be no need for the Sacraments - which Jesus himself installed into His Church. Since Jesus was fully human he understood our weaknesses; in his mercy he commissioned to his apostles the authority to forgive sins via the Sacrament of Reconciliation. This is precisely why Jesus left His Church a means to become reconciled back to God, even though our human limitations cause us to fall.
The notion that “I AM GOOD ENOUGH,” in the eyes of the devout Catholic Christian, is not the way one perceives himself. He / she recognizes their need for a savior, but not as a once in a lifetime event (being saved once), but a daily conversion of growing in holiness. This comes to us through the Mass and through the Sacraments (being saved perpetually).
‘Good works’ are a cooperation with the Holy Spirit, it’s the Trinity working through us, and we must strive to transform our will to the Father's Will. Not by my own ability, but by the grace give me according to His good measure. Sincerity and unselfish love marks a Christian as true Disciples of Christ.
Scriptures Related to Being Judged by A Person's Deed:
2 Cor 5:10 – “Receive recompense according to good or evil.”
2 Cor 11:15 – “The end will correspond to their deeds.”
1 Peter 1:17 – “God judges impartially according to one's work.”
Rev 20:12-13 – “Dead judged according to their deeds.”
Col 3:24-25 – “Will receive due payment for whatever you do.”
Mt 6:16-12 – “Store up for you treasures in heaven.”
Consider these scriptures about judgement:
Romans 1:24 – “Therefore, God handed them over to impurity through the lust of their hearts."
Romans 1:26 – “Therefore, God handed them over to degrading passions.”
Romans 1:28 – “God handed them over to their discerning mind to do what is improper.”
Romans 2:5-8 – “By your stubbornness and impenitent heart, you are storing up wrath for yourself for the day of wrath and revelation of the just judgment of God, who will repay everyone according to his works: eternal life to those who seek glory, honor, and immortality through perseverance in good works, but wrath and fury to those who selfishly disobey the truth and obey wickedness.”
Since by our sinfulness and cooperation with the Devil, nailed the only begotten, Jesus Christ, to his cross, how much more in faith through baptism and our good deeds will glorify him?
Finally, Catholic's view of good works is that works provide the evidence of one’s faith. These works demonstrate one's cooperation with the Spirit, in acts of mercy, toward our neighbor. "He will answer them, ‘Amen, I say to you, what you did not do for one of these least ones, you did not do for me’" (Matt 25:45).
