@Jimmy_Sellers Are you asking if there is any evidence in the Epistles that the Jews or Gentiles cared if Jesus was man or Messiah?
Since I do not understand the question fully I cannot answer it, but here are some passages that highlight Paul’s understanding of the the relationship the Jews and Gentiles had toward the Gospel.
I think you will notice a common theme in the Epistles that the epicenter of contention was the cross. The Gentiles struggled to stop living lives of sin - to be crucified to their flesh - or they trusted in pagan philosophy rather than the “foolishness of God”. The Jews wanted to be saved by the law and their own righteousness rather than by faith through the work of Christ on the cross.
I also think in the Epistles, since Paul was talking to Churches, he generally was addressing Judaizers - false teachers infiltrating the Church - rather than the Jews who were chasing him around trying to stone him.
1 Cor 1:22-24 - Jews demand signs and Greeks look for wisdom, but we preach Christ crucified: a stumbling block to Jews and foolishness to Gentiles, but to those whom God has called, both Jews and Greeks, Christ the power of God and the wisdom of God.
Galatians 3:10-14 - For all who rely on the works of the law are under a curse, as it is written: “Cursed is everyone who does not continue to do everything written in the Book of the Law.” Clearly no one who relies on the law is justified before God, because “the righteous will live by faith.” The law is not based on faith; on the contrary, it says, “The person who does these things will live by them.” Christ redeemed us from the curse of the law by becoming a curse for us, for it is written: “Cursed is everyone who is hung on a pole.” He redeemed us in order that the blessing given to Abraham might come to the Gentiles through Christ Jesus, so that by faith we might receive the promise of the Spirit.
Romans 6:1-4 - What shall we say, then? Shall we go on sinning so that grace may increase? By no means! We are those who have died to sin; how can we live in it any longer? Or don’t you know that all of us who were baptized into Christ Jesus were baptized into his death? We were therefore buried with him through baptism into death in order that, just as Christ was raised from the dead through the glory of the Father, we too may live a new life.
Of course Jesus’ identity as God is contentious among both.
Do any of those verses spark any thoughts?
