The question if we have to keep al the Jewish commands.. is actually irrelevant.. because 613 commands are based and written in the talmud. (Makkot 23b)
Interesting is the writing from D.Hausdorf: from Adam till Ezra (translated)
He said: The 10 words are written in two tables.
first table is relationship God-human
* There is only one God, who took us from Egypt
We have to understand that the Lord watch over us, in everything.
* Serve only God, don't make idols
God is the only one who is in controle. No other force/power got the final word. Everybody got a special relationship with the Lord. You have to respect that.
* Don't speak the name of God without a reason
God is your Creator. He is your King. Not like a normal friend.
* honour the 7th day of the week, the Shabbath. Don't work at that day
This day is to serve God. That we don't forget the relationship with him.
* hounour your father and your mother always
We have to be thankful to the one by authority of God, who gave us the live.(Not literally translated, but in my own words) In the talmud is written; The wine belongs to the hostess, but it belongs to the waiter too.
The second table is the relationship between human and human
* don't kill a person
Everybody is created by Gods image. You have to respect it. For the Lord this person is important. So, he had to be important for you too.
* don't marry a woman who is married already.. (or got a relationship with her)
love is not a free letter (I don't know if this is a right English saying)to righteous everything.
* don't steel
Try not advantage your self, by what is not yours
* don't lie
Every person is a judge. So we have to be righteous.
* don't be jealous
Be happy if your neighbour is succesful. Share in the sorrows from your neighbour.
This is a Jewish point of view of the 10 commands. Published by the Dutch-Israeli community(Not Messianic).
The Law or Torah is meaning teaching. And, the most Christians are thinking in Laws instead of teaching. And that was just the problem what I think with the Pharisee in the time of Jesus and Paul.
When we read Rom 14. I think the principe of the Torah is there written. If you do some. Do it for the Lord. Not because other people think you have to do. You got a relationship with the Lord. But the pitfall of the human (and I am talking to myself too) we argue a lot about the Lord.. about the Bible and we are doing that without the Lord. But it is our conviction.. and forget that the person him/her self got a relationship too with the Lord. We are rude, and forget to be respectful.
