When Paul writes we are now justified he means
we are declared not guilty; or
Christ’s sacrifice established a new covenant that included Gentiles.
When Paul writes that we have been justified, he has in mind that we have been declared not guilty. We can detect this is the case for two reasons. First, Paul uses the passive voice and aorist tense for the verb to justify,
which indicates that the justification is something that happens to us in the past. Second, this justification is secured by the blood of Christ. The blood of Christ correlates Christ’s ministry with the Old Testament sacrificial system, so that Paul is saying Christ’s sacrifice of atonement secures our past justification. Of course, the sacrifice of atonement was used to forgive the sins of the Israelites, which means that to be justified in the past by Christ’s sacrifice is to be declared not guilty in the past by Christ’s sacrifice.
Some contend that when Paul says we have been justified, he has in mind that we have been included in the new covenant. The argument here is that the Old Testament sacrificial system was how God established the covenant with Israel, so by using sacrificial language, Paul has in mind that God justified us through Christ in the sense that we are now included in the covenant.
The problem is that this argument confuses the means and content of reconciliation with the promise of reconciliation. For the means of reconciliation is sacrifice, and the content this achieves is forgiveness. Of course, God also promises to provide reconciliation, which is established by the fact that he made a covenant with us. Still, we should not confuse the promise from the means and content.
Thus, Christ is the sacrifice that has justified us in the sense that, through his sacrifice we have been declared not guilty.
Interpretation 1:
Paul means we are declared not guilty.
Summary:
Paul explains that since we have been declared not guilty by the sacrifice of Christ on the cross, we will not have to endure the wrath of God on judgment day. In other words, although we are guilty, we are justified in that because of Christ, we are declared not guilty.
That we are declared not guilty means we can let go of the guilt we carry for our past sins. When we repent and put our faith in Jesus Christ, God declares us righteous for Christ’s sake, removing our guilt and shame.

Minor differences:
Our authors agree that when Paul writes that we are now justified, he means that we are now declared not guilty because of the sacrifice of Christ.
Richard Longenecker characterizes justification as forensic.1 In other words, justification has to do with our legal status before God changing from guilty to not guilty because of the sacrifice of Christ.
Douglas Moo characterizes justification similarly, referring to it as a past declaration of acquittal.2 Thomas Schreiner refers to it as the removal of guilt and enmity with God.3
