How do you know were you there?! I love seeing this talk about "Paul the Hellenized Jew". Hahaha! Considering the fact that he studied Torah under Rabbi Gamiliel, one of the greatest Sages Judaism produced, I find it highly unlikely that he had a Hellenic view of the scriptures. Just because he had a knowledge of the greek language doens't mean he wasn't an orthodox Jew.
How do you know that Paul studied under Gamaliel, besides the fact that he CLAIMED it? He never gave any details about it to make anyone believe that it was actually true.
In Acts 23, when Paul and Gamaliel should have encountered one another, Gamaliel is nowhere to be found.
