"First, the Catholic must understand that, in the Protestant mind, man is absolutely saved by his own works apart from faith and God's grace, but because of sin man is now unable to save himself and must have Jesus do those works for man in man's place. Human works alone (apart from faith and grace) are still what save us in the Protestant mind, the only thing that changes is that now Jesus does that work in man's place."
The Law of God requires perfect obedience. If sin did not exist, then there would be no need for God to show forgiveness, as there would be no spiritual corruption in the first place. There would be no need to speak of "getting saved," as everything would already be functioning in a perfect order. But the fall of man has brought about sin and thus condemnation. God has voluntarily paid an infinite sin debt on our behalf because of His love for us. He saved us because He is gracious. The idea that a man can be saved by keeping the Law (assuming he even has the ability to) would be true only in a hypothetical sense.
"This is completely contrary to the Catholic understanding of salvation, in which man can only be saved by faith and grace, never by his own works no matter how good those works are."
The fact that Catholics are required to obtain and maintain their justification on the basis of good works proves that it is indeed works-based. The concepts of purgatory and the treasury of merit further render the claims of the author unconvincing. In Roman Catholic theology, God gives grace through baptism so that man can perform good works to merit more grace.
"Without going into detail on each of these passages [Romans 4:1-3, Galatians 3:10-12, Ephesians 2:8-9, Philippians 3:4-7, and Titus 3:4-5], notice that in the 'plain reading' of these texts, there is no mention of the works in question being 'tainted by sin'. In fact, such a reading would make these texts nonsensical. The only reason given for why works don't save is to prevent boasting. That's it."
The texts that Nick mentions are quite straightforward, in that they say we are not saved by works of righteousness. We are saved because God is loving and merciful. He is literally reaching out to helpless mankind because of His love. The contexts of each passage that Nick lists makes mention of our problem of sin. We are not deserving of His salvation.
The Bible tells us that the wrath of God is revealed against all unrighteousness and ungodliness (Romans 1:18). We have all sinned against Him. We all have a stained record. Therefore, we have all incurred His wrath and judgement. But Jesus Christ offered Himself up as a sacrifice to appease that wrath. He is our propitiation (Romans 3:24-25). Christ is our advocate before God the Righteous Judge (1 John 2:1-2). The Law is what makes us conscious of sin (Romans 7:7). It condemns us. Christ obeyed the Law perfectly in our place (Romans 8:1-4). He took our punishment. We have redemption through Christ's blood (Ephesians 1:7-8). We are purified by placing our trust in His work. He is our reconciliation. His grace is unmerited.
"Now it is true that the "works" Paul has in mind are "Works of the [Mosaic] Law," which are the 613 individual Commandments found in the Torah (Genesis, Exodus, Leviticus, Numbers, and Deuteronomy), centered around the Ten Commandments. But even this doesn't change anything, because keeping the Law never did save."
We can agree with the author that nobody was saved by keeping the Law. Justification has never been by works. Nonetheless, the contexts of Ephesians 2:8-9 and Titus 3:5 nowhere limit "works" as exclusively referring to the Mosaic Law. That is not what the Apostle Paul said.
"And it is true that all men come into this world dead in sin and separated from God, but even that's not the point behind Paul's repeated 'works don't save' statements."
It would be proper to allow the reader to decide who has a more reasonable interpretation of Scripture by citing one of those "not by works" passages that the author alludes to in context:
"But God, being rich in mercy, because of His great love with which He loved us, even when we were dead in our transgressions, made us alive together with Christ (by grace you have been saved), and raised us up with Him, and seated us with Him in the heavenly places in Christ Jesus, so that in the ages to come He might show the surpassing riches of His grace in kindness toward us in Christ Jesus. For by grace you have been saved through faith; and that not of yourselves, it is the gift of God; not as a result of works, so that no one may boast." (Ephesians 2:4-9)
If the "works" spoken of in Ephesians 2:8-9 are a reference to the works of the Mosaic Law, then why not interpret Ephesians 2:10 in the same fashion (created in Christ Jesus for good works of the Mosaic Law)?
"Protestants think you are worthy of Eternal Life upon being Justified, but that's not what Paul teaches. In reality, Justification and being Judged worthy of Eternal Life happen at two different times in a person's life - and to confuse the two events and turn them into one event the way Protestants do is a huge mistake."
So, a person who is justified in the sight of God is not necessarily entitled to heaven? That statement is ridiculous, as well is it illogical. If an individual is converted to Christianity and one day later just so happens to die in a vehicle accident, then would he or she not be allowed into the kingdom of God at that point? Was that person not saved? Is that person automatically going to hell for potentially not getting a chance to greet a neighbor or feed the poor?
