When Paul says faith in Jesus Christ,
he means
faith in Jesus Christ.
the faithfulness of Jesus Christ.
Most likely, Paul has in mind faith in Jesus Christ.
We can deduce this for two main reasons. First, an important theme for Paul is the contrast between works of the law and faith. In his letter to the Galatians he sharply contrasts works of the law with faith in Christ (Galatians 2:16). Further, in Romans 3:27–28 he refers to being justified by faith, not the works of the law. Likewise, in Romans 3:20 Paul says that no one will be justified by works of the law. So it is fitting that he would follow this up by saying God’s righteousness is revealed through faith in Christ. Second, Paul refers to the importance of faith in both Romans 1:17 and Romans 3:26, where he writes that the righteous will live by faith and that God is the justifier of those who have faith. So it is likely that Paul has in mind faith in Jesus Christ.
Some contend that Paul has in mind the faithfulness of Christ.
They argue this for a few reasons. For one, these contend that the Hebrew notion of faith always included faith
and faithfulness.
Also, these point out that Paul is contrasting God’s faithfulness with Israel’s unfaithfulness, and that he mentions Jesus’ obedience in Romans 5:19. Finally, these contend that Paul would have been familiar with Isaiah 11:5, where the righteousness and faithfulness of the Messiah are mentioned.
Now, that the Hebrew term for faith can mean both faith
and faithfulness” is not a strong argument, because we know that Paul uses the Greek term πίστις to refer to individual faith in some contexts (Romans 3:25, Romans 3:26), so why should we not take him to do so in Romans 3:22. Also, while it is true that Paul contrasts God’s faithfulness with Israelite faithlessness, he more obviously contrasts works of the law with faith in Jesus Christ (Romans 3:27–28). So why shouldn’t we take him to have works and faith in mind. Third, Paul’s familiarity with Isaiah is not as relevant as the immediate context of Romans 3:22, where Paul seems to be focused on how Jews and Gentiles participate in salvation.
Thus, Paul likely means through faith in Jesus Christ.
Interpretation 1:
Paul means faith in Jesus Christ.
Summary:
Paul has outlined the fact that because all sin, no one will be justified before God by the works of the law. Now he explains that God’s saving righteousness is revealed through faith in Jesus Christ.
Faith in Jesus Christ is the contrast to works of the law. In other words, we cannot save ourselves through good works. Instead, we place our trust in Jesus Christ, and he saves us.

Minor differences:
Our authors agree that when Paul writes διὰ πίστεως Ἰησοῦ Χριστοῦ, we should translate this through the faithfulness of Jesus Christ.
For Richard Longenecker, there is some ambiguity in the phrase, in the sense that Paul could mean the faithfulness of God in Jesus Christ
or the faithfulness of Jesus Christ.

For Leon Morris, the ambiguity lies elsewhere. In particular, Morris posits that Paul is purposely ambiguous with the phrase, so he could either mean through the faithfulness of Jesus Christ
or through faith in Jesus Christ.
Morris contends that faith in Jesus Christ
is certainly on Paul’s mind in this section, in that faith in Christ is only important because of the faithfulness of Jesus Christ.
