Jesus was a good 1st century rabbi , a prophet, who after his death got enveloped into some of the then current speculative theological ideas and concepts present him as he God.
The central problem is that the person Jesus became far more important to christians than did his message of repentance. His supposed role as a warrior messiah or prophet who miraculously at the hands of Israel’s enemies overshadowed by trinitarian idea about a dying and resurrected redeemer.
Even all of the scriptures (the Torah and the Gospel) show that the commandments taught by Moses are more important for people to follow (for Jews) than theology or miracles when it comes to knowing the biblical “truth.”
Even Gentiles are taught to observe the basics (Acts 15)
