“we are justified by faith… not by works of observing the law.”

After standing together with Peter in Jerusalem and establishing the truth that we are saved by faith in Christ – nothing else and nothing more – Paul confronts Peter in Antioch, a Gentile city. Peter, fearing the Judiazers, stopped eating with the Gentile believers. Peter had not changed his convictions! He knew that the laws were only Jewish customs– he was hypocritical.
