I want to know what the RC church means when it says that man merits eternal life?
I want to answer by providing some biblical evidence of the general Catholic view. I think that once we see the overall picture of justification by grace through faith and works and a the true nature of saving faith–not just a mere trust or belief–then I think the more specific question can be more easily answered.
- The individual cooperates with God; though all good we do comes from his grace: “And each will receive wages in proportion to his labor. For we are God’s co-workers; you are God’s field, God’s building” (1 Corinthians 3:8-9).
- We are not saved my merely human works. But once in a relationship with God, works are of a different sort: He provides the grace to make such works fruitful and meritorious with regards to one’s salvation: “For by grace you have been saved through faith; and this is not your own doing, it is the gift of God-- not because of works, lest any man should boast. For we are his workmanship**, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them**” (Ephesians 2:8-10).
- Once in the state of justification, we have received the Spirit and become adopted children of God. It is this difference of relationship with God that allows our works to be different: They now proceed from God’s spirit. “For you did not receive the spirit of slavery to fall back into fear, but you have received the spirit of sonship. When we cry, “Abba! Father!” it is the Spirit himself bearing witness with our spirit that we are children of God, and if children, then heirs, heirs of God and fellow heirs with Christ, provided we suffer with him in order that we may also be glorified with him” (Romans 8:15-17).
- Truly partaking in the divine nature (see 2 Peter 1:3-4) and given the Spirit, we can do good works, the kind of works that are “excellent and profitable to men” (Titus 3:8). It is through our actions that we show God what we truly want-- whether we love Him or not–and ultimately produce the fruit of eternal life: “Make no mistake: God is not mocked, for a person will reap only what he sows, because the one who sows for his flesh will reap corruption from the flesh, but the one who sows for the spirit will reap eternal life from the spirit. Let us not grow tired of doing good, for in due time we shall reap our harvest, if we do not give up” (Galatians 6:7-9). And as Romans 6:22 makes clear, such sanctification leads to eternal life: “But what profit did you get then from the things of which you are now ashamed? For the end of those things is death. But now that you have been freed from sin and have become slaves of God,** the benefit that you have leads to sanctification, and its end is eternal life"** (Romans 6:21-22).
Jesus plainly tells that an individual must bear fruit to enter Heaven. If a “tree that does not bear good fruit” will be “thrown into the fire,” then bearing good fruit—good works—are necessary for salvation. Simply acknowledging Christ as Lord is not enough: we must
do the will of God: “By their fruits you will know them. Do people pick grapes from thornbushes, or figs from thistles? Just so, every good tree bears good fruit, and a rotten tree bears bad fruit. A good tree cannot bear bad fruit, nor can a rotten tree bear good fruit.
Every tree that does not bear good fruit will be cut down and thrown into the fire. So by their fruits you will know them. “
Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but only the one who does the will of my Father in heaven.” (Matthew 7:16-21)
- Of course, the judgment scenes scream works as the basis of where one will spend his or her eternal destination: “…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.” (Romans 2:5-8)
The Bible is clear that we have absolutely no claim on God. It is His initiative–His mercy. We do not do anything of ourselves to “get right” with God; but by His grace, in the initial process of conversion, we do believe, repent, and be baptized, as He said to do. The consequence of this is that we are His children. We have his very presence in us–His Spirit in our spirit. Our nature has been uplifted by the virtue of Charity (without this, Paul would be “nothing,” remember?). God’s grace reigns in our souls. Now, being in the Family of God, as adoptive children, God inspires us more and more to grow in grace. From that moment of conversion, we are justified so long as we don’t turn *our *backs on Him. Good works make us mature Christians: They increase Charity and Grace in our souls–making us more God-like, so-to-speak. Good works justify us (as James 2 says, and I didn’t even mention that yet!), precisely because of this progressive nature of growing in grace. Saying good works justify does not mean that there is some set number of works one must do to be saved; rather, it means that in one’s already state of justification, he/she increasingly becomes–by God’s grace–holy. So ultimately, eternal life is definitely based on a promise coming from God , and this promise is renewed everytime someone chooses God’s will inspired by God’s grace.
