Christ never legislated anything. Rather, He seemed to take great offense with the Jewish leaders who did.
When we allow our nation to become a Theocracy, we start heading down exactly the same path as the ancient Jews.
Christ never legislated anything?
"I tell you, anyone who looks on a woman with lust has committed adultery with her in his heart."
"If you are offering your gift at the altar and there remember that your brother has something against you, leave your gift there before the altar and go. First be reconciled to your brother, and then come and offer your gift."
"But I say to you that everyone who divorces his wife, except on the ground of sexual immorality, makes her commit adultery, and whoever marries a divorced woman commits adultery."
"But I say to you, Do not take an oath at all, either by heaven, for it is the throne of God, 35or by the earth, for it is his footstool, or by Jerusalem, for it is(BM) the city of the great King. 36And do not take an oath by your head, for you cannot make one hair white or black. 37Let what you say be simply 'Yes' or 'No'; anything more than this comes from evil."
Of course He did.
What He criticised the Jewish leaders for was being hypocrites (Matt 23) and for adding their own human traditions to God's law (Mark 7). Yes, God's LAW.
But what else did He say about the Law?
"Do not think that I came to abolish the Law or the Prophets; I did not come to abolish but to fulfill. 18"For truly I say to you, until heaven and earth pass away, not the smallest letter or stroke shall pass from the Law until all is accomplished." (Matt 5:17-18)
He had a pretty high opinion of the Law, since it came forth from God and all.
I didn't argue for a theocracy. I said that any law is a moral statement.
It's wrong to go faster than 25 mph in a school zone.
It's wrong to burn down someone's property.
It's wrong to hold up a bank.
It's perfectly fine to stick a scalpel into a nearly-born baby's brain and then dismember her and 'birth' her that way.
It's perfectly fine for the gov't to force me to give them lots of the money that I earned.
It's wrong to kidnap a woman in order to protect her baby from the scalpel at the abortuary to which she is en route.
So the struggle in gov't of a nation is WHOSE morality will be imposed, not WHETHER it will be. EVERY law is an imposition of morality on everyone else. Even a nation that makes no laws makes a moral statement - it's not a high-enough moral priority to make any laws governing behavior.
