I can destroy this criticism very easily. Focus your attention to the following verses......
Deut. 9:15
So I turned and came down from the mount, and the mount burned with fire: and the two tables of the covenant were in my two hands.
This is when Moses first received the Ten Commandments and the Nation of Israel was brought under the Mosaic Law.
1 Kings 8:21
And I have set there a place for the ark, wherein
is the covenant of the LORD, which he made with our fathers, when he brought them out of the land of Egypt.
This is when King Solomon finished the First Temple in Israel.
Now, turn your attention to......
Galatians 3: 23-25
But before faith came, we were kept under the law,
shut up unto the faith which should afterwards be revealed.
Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith.
But after that faith is come, we are no longer under a schoolmaster.
This is made even more apparent when reading Hebrews.......
Hebrews 8:6-13
But now hath he obtained a more excellent ministry, by how much also he is the mediator of a better covenant, which was established upon better promises.
For if that first covenant had been faultless, then should no place have been sought for the second.
For finding fault with them, he saith, Behold, the days come, saith the Lord, when I will make a new covenant with the house of Israel and with the house of Judah:
Not according to the covenant that I made with their fathers in the day when I took them by the hand to lead them out of the land of Egypt; because they continued not in my covenant, and I regarded them not, saith the Lord.
For this is the covenant that I will make with the house of Israel after those days, saith the Lord; I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people:
And they shall not teach every man his neighbour, and every man his brother, saying, Know the Lord: for all shall know me, from the least to the greatest.
For I will be merciful to their unrighteousness, and their sins and their iniquities will I remember no more.
In that he saith, A new covenant, he hath made the first old. Now that which decayeth and waxeth old is ready to vanish away.
Jesus' death is how the 'new Covenant' was signed for Christians. The reason you couldn't understand was because you have neither read the entire text nor have you read it in-context.
It's not that I haven't read it or read it in context. It's that, philosophically, I cannot get behind the idea that God's own word can just change. The idea that God's word can evolve fundamentally betrays what you claim God's very nature to be. But let's say for instance that it can. Am I supposed to take the word of some a$$hole named "Paul" writing letters to different groups of Jews telling them how to live their lives? Jesus himself said "I did not come to abolish the law", so why is Paul's bullshyt taken as gospel?
But anyway, that's beside the original point. You say I haven't read the whole thing or read out of context, but you cherry pick what you like. You glean what you want to out of the Bible, but you don't understand the implications of all these contradictions. Notice you didn't even ATTEMPT to address the multiple instances of slave-owning and slave-beating promoted in the New Testament, some written by your boy Paul himself. Because you have no answer. You only get what you want to get out of the book and ignore the rest.
So even if I accept your premise that Jesus abolished the Old Testament, even though he said himself that he did not, there are still MANY instances in the New Testament that demonstrate ownership, mistreatment, and beating of slaves. You can't deny this. You didn't even try. So we can go back and forth about the validity of the OT if we want, but there is still plenty of savagery in the NT, so it doesn't matter.
You have no argument here, at all, whatsoever. But Christians' desperate need for a sense of moral superiority will make you forever cling to the ideas taught to you as a child that "Christian" and "good" are somehow synonyms. It's disgusting.
