Everything possible is theologically wrong with two-covenant theology (Jews saved by law, gentiles by Christ) — it is unloving to Jewish people because it withholds their own Savior from them.

Jesus is literally the Jewish Savior; telling Jews they have a separate law-based path denies them the gospel. The gospel goes to the Jew first (Romans 1:16). Galatians shows the law's purpose is to condemn and lead to Christ — it cannot save.
