That contradicts the entire message of the New Testament. Salvation is by works - not works of the law, but works of faith. Faith with no action - prayer, love, taking care of your neighbor, etc. is dead and not real. Good works are the form of faith. So a man who claims faith but does not pray and live piously and charitably will die the death.
Many non-Catholics confuse St. Paul preaching against attempting salvation by the works of the Law (the Old Covenant) - "For we account a man to be justified by faith, without the works of the law" (Romans 3.28), with achieving salvation by good works in Christ. Jesus explicitly said in Matthew 7.21-23 that he will be telling the evil believers crying out "Lord, Lord" to "depart from me". Those who live the faith by being charitable to their neighbor will be welcomed into the Kingdom (Matthew 25.31-46, James 1.22-27).
Catholics misunderstand the Law.
No, they do not. It is the old covenant.
"Now that faith has come, we are no longer under the supervision of the law."
Nobody is saying that we are.
We are free from the obligation of trying to live by the Law when we've put our faith in Christ for salvation because we are now sons of God through faith.
And faith without works is dead. Don't confuse those works with "works of the Law".
Really?
Matthew 5:21-22 21 “You have heard that it was said to those of old, ‘You shall not murder; and whoever murders will be liable to judgment.’ 22 But I say to you that everyone who is angry with his brother will be liable to judgment; whoever insults his brother will be liable to the council; and whoever says, ‘You fool!’ will be liable to the hell of fire.
Matthew 5:27-28 27 “You have heard that it was said, ‘You shall not commit adultery.’ 28 But I say to you that everyone who looks at a woman with lustful intent has already committed adultery with her in his heart.
Matthew 5:48 You therefore must be perfect, as your heavenly Father is perfect.
1 John 3:15 Everyone who hates his brother is a murderer, and you know that no murderer has eternal life abiding in him.
Don't confuse those works with "works of the Law".
Any works outside of the Law are sin. The Law DEFINES what good works are.
If you don't realize that the Law really teaches what Jesus taught in the Beatitudes, you don't know the Law very well. Any of the works Jesus taught in the Beatitudes are already part of the Law.
Catholics really do misunderstand the Law.
