You seem to equate "encompasses" as if equal.
Fulfilling the Law was the Sermon on the Mount.  Going beyond the moral law of proportionality to one of disproportionally, "But I say to you love your enemies ..."  This is what Christians choke on.  Why so many are for capital punishment. Why is it that fundamental Prots and RCs default to Jewish texts when the gospel are the upgraded version.  They still remain an incredibly challenging code of conduct, observed more as an exception by Christians than the norm.  Many prefer Moses' proportionality...a life for a life, etc.
More Christians are more Jewish!
