The point is not that the “old” (Judaism) is wrong or evil but that its time has passed. Judaism was "worn out" (palaios) and in need of something brand new (kainos), the Gospel. Jesus did not come to reform ritualistic Judaism but to replace it and clothe men with "garments of salvation", representing not their self-righteous works (as in Judaism) but His righteousness (Isa 61:10+, Ro 3:22+), for as Paul wrote "all of you who were baptized into Christ have clothed yourselves with Christ." (Gal 3:27+).
