Joseph was born before God gave the Jewish Religious Law to Moses. He is not a religious Jew. I don’t really see any way around that.
Even Paul argues the same when considering Abraham, who, Paul says, was before the giving of the law. Abraham was justified, according to Paul, not by keeping the law, but by faith.
Abraham believed God and that was credited to him as righteousness.
I didn’t call Jacob (Isreal), or even Joseph, a Jew or Hebrew. Or for that matter a religeous zealot of what is known as the One True God. I just defined that Jacob son of Issac, Son of Abraham, and brother of Esau, also known as Isreal was the Father of Joseph as well as Joseph’s twelve brothers who became the 12 tribes of Isreal.
Well stated xzins.
BTW, it is a misnomer to refer to the Bible as “Christian” as separate from “Jewish”, considering every author of each book was Jewish, and the main object of faith throughout the Word is God whose Son is also Jewish and King of the Jews.
