[Dr. Eckleburg]

Roman Catholics incorrectly believe that their good works are required in order to receive salvation.

That is not what Scripture teaches. Good works are the evidence of salvation; not the cause of it.

[Cincincinati Spiritus]

You must cite. That is false, and Catholics do not so maintain. A simple proof is the practice of infant baptism.

[Cincincinati Spiritus]

Roman Catholics incorrectly believe that their good works are required in order to receive salvation.

Let me clarify, salvation is achieved by grace. Our good works are required but they do not merit us salvation, that is by grace. And even our good works are inspired by the grace of God and done with the help of the grace of God. Now that cooperation is said to merit us a greater reward, but still all is only done by God's grace. I hope that helps. Both Augustine and Aquinas have written well on this.
