"Grace is primary in the whole process, so in that very real sense we can describe our system as “saved by grace alone” -- whereas we can never say “saved by faith alone” (i.e., with works playing no part at all in salvation) or “saved by works alone.” The true Catholic position will always include the works alongside grace and faith."

"If anyone says that man can be justified before God by his own works, whether done by his own natural powers or through the teaching of the law, without divine grace through Jesus Christ, let him be anathema." (Council of Trent, canon 1)
The grace of God does not come about as a result of the doings of man (Romans 11:6). Simply put, to speak of grace being infused at the moment of water baptism and being maintained through good works is a contradiction of terms.
Rome requires one to do good works in order to attain and maintain justification. It teaches that one must attain an inherent righteousness in order to be accepted by God. That line of thinking runs contrary to texts such as Psalm 14:2-3, 49:7-9, 130:3, Isaiah 64:6, Luke 18:9-14, Romans 3:10-12, 23, Galatians 3:10, and Philippians 3:3-9.
The point of contention is not whether our walk with God is to be characterized with a desire to serve Him. Our good works are a display of His grace in our lives. However, they are not to be viewed as meritorious in His sight. Our grounds for justification before God is the shed blood of Jesus Christ alone (Romans 5:19).
If justification is "not of ourselves" and "not as a result of works" (Ephesians 2:8-9), then that means faith alone is the instrumental cause of justification before God. There are no good deeds that can save us from eternal condemnation.
Elsewhere, the Apostle Paul says, "not by works of righteousness which we have done" (Titus 3:5). He continues on that thought with a stark contrast, "but according to his mercy he saved us." This dichotomy is prevalent throughout the writings of Paul. He would most definitely have condemned the sacramental system of justification taught by the Church of Rome.
