Acts 14,15

Because there was dispute over whether Gentiles needed to observe the law of Moses including circumcision etc., Paul and Barnabas were sent back to Jerusalem to appear before the Apostles and church leaders to get a ruling.

Peter, because of his revelation at the house of Cornelius, spoke of his conviction that Gentile hearts could be purified of sin by their faith in Christ in the same way that a Jew could receive salvation … a work of God’s grace.

The whole question of whether following the law merited salvation was settled. Faith and trust in Christ was the criteria, not observing dos and don’ts.
