The woman caught in adultery is actually a good point to consider. Personally I really appreciate it when people bring up Biblical points to consider like this one as opposed to the ,"I just don't feel like it is right type arguments. I have felt a lot of things in the past that turned out to be erroneous.
With that said, adultery was specifically condemned in the Old Testament (the Law of Moses), in Gen. 9:4 God tells the world that man was made in His image and if someone takes man's life, his life is required in its stead was given to all men by God before the Isrealite nation was established (1,000+ years I believe).
The people trying to kill the woman caught in adultery were the teachers of the law [of Moses] and the Pharisees. (By the way, these lawyers and Pharisees weren't well thought of by Jesus and his followers because they were hypocrits). These people were judging her by the law of Moses as they themselves were breaking it and Christ asked them to examine themselves first.
But the biggest example in my mind that capital punishment wasn't done away with in the New Testament is the fact that the New Testament was implimented by capital punishment (which actually happened to be after the adulterous woman issue). God always required blood for our sins. In Moses' time God would use the blood of animals to push sins towards the cross and in our time God uses the blood of Christ. Even with the blood of animals God still required death by those who took man's life. God is gracious and still pardoned people even when Isreal was it's own nation. He pardoned David for being an adulterer and murderer (by having Uriah killed) but even then someone's blood was still required and sadly enough that turned out to be the innocent baby of David and Bathsheba (that's another truth, someone who is innocent is the only viable sacrifice for the guilty). Basically to put it bluntly, someone's got to die.
That is not to say that man is hopeless, as you see while on the cross Christ forgave the thief that was dying next to him. Despite what our earthly death is (due to our sin or not) we can still be with Him if we so choose).
ETA: To address your last issue of turning the other cheek and forgiving, you are right, as a Christian we must do that. But if you notice that others (in our case our legal system) are still responsible for holding the guilty accountable. As we all know Christ forgave us and those who put him to death, Peter then went and held them accountable on the day of Pentacost. There is to be justice (and mercy) while we are here. If not then we would have no reason for any justice system at all. If you remember Rom. 13:1-7 says
1Everyone must submit himself to the governing authorities, for there is no authority except that which God has established. The authorities that exist have been established by God. 2Consequently, he who rebels against the authority is rebelling against what God has instituted, and those who do so will bring judgment on themselves. 3For rulers hold no terror for those who do right, but for those who do wrong. Do you want to be free from fear of the one in authority? Then do what is right and he will commend you. 4For he is God's servant to do you good. But if you do wrong, be afraid, for he does not bear the sword for nothing. He is God's servant, an agent of wrath to bring punishment on the wrongdoer. 5Therefore, it is necessary to submit to the authorities, not only because of possible punishment but also because of conscience. 6This is also why you pay taxes, for the authorities are God's servants, who give their full time to governing. 7Give everyone what you owe him: If you owe taxes, pay taxes; if revenue, then revenue; if respect, then respect; if honor, then honor.
Also, take note that Paul refers to the authorities bearing the sword. That would also be an indication of the death penalty.
You seem to have misquoted,
Gen 9:4 says:
"But you must not eat meat that has its lifeblood still in it"
I agree with Jesus getting them to examine themselves, yet still, after they left, he said
(John 8:9-11)
"Woman, where are they? Has no one condemned you?" 11"No one, sir," she said.
"Then neither do I condemn you," Jesus declared. "Go now and leave your life of sin."
With him being our example, and his judgment being righteous, aren't we to follow suit?
With that said of course, I'm not saying they should be let free but IMHO you will reap what you sow, they should go to jail...
I understand a blood sacrifice was needed for every sin, and it has to be a pure one, innocent, thus why Jesus died for ours, after his death we no longer need to kill things when we sin. His blood is enough.
Roman 12:1
[
Living Sacrifices ] Therefore, I urge you, brothers, in view of God's mercy, to offer your bodies as living
sacrifices, holy and pleasing to God—this is your spiritual act of worship.
What I don't understand is if the sacrifice has to be pure and holy, then how can we die for our own sin and it be atoned for?
Possibly off topic: I've wondered about the above scripture about God putting authorities in place... In the world today many dishonor Him greatly. Some disallow the worship of him...
