In Acts 10—11, in the encounter of the Torah-observant Peter with the God-fearing Gentile Cornelius, we see what "fulfill" looks like for the apostles: it means some radical revisioning without abolishing. Paul's words about accommodating himself to Gentile ways in 1 Corinthians 9:19—23 also illustrate how the apostles "applied" this claim by Jesus. Second lesson in Bible reading: looking to Jesus means following him and through him the Torah.
