Römer 3:8

JEWISH OBJECTIONS ANSWERED. (Rom 3:1-8) What advantage then hath the Jew?--that is, "If the final judgment will turn solely on the state of the heart, and this may be as good in the Gentile without, as in the Jew within, the sacred enclosure of God's covenant, what better are we Jews for all our advantages?" Answer:

The apostle, in this chapter, carries on his discourse concerning justification. He had already proved the guilt both of Gentiles and Jews. Now in this chapter, I. He answers some objections that might be made against what he had said about the Jews (Rom 3:1-8). II. He asserts the guilt and corruption of mankind in common, both Jews and Gentiles (Rom 3:9-18). III. He argues thence that justification must needs be by faith, and not by the law, which he gives several reasons for (Rom 3:19 to the end). The many digressions in his writings render his discourse sometimes a little difficult, but his scope is evident.

3:8 some people even slander us: Paul is referring to misrepresentations about his teaching on justification by faith. If a person is made right with God by faith alone, through God’s grace and apart from works, it could seem as if the Good News allows believers to sin because their sin is forgiven when confessed (see 6:1). One of Paul’s purposes is to help the Roman Christians understand that such misunderstandings are without basis.
