If he was the messiah ...
Please keep in mind that I am not claiming Jesus is the Messiah in this discussion. (I think he is, you think he's not)
My singular point in this discussion is that Jesus claimed to be God and it was for that that he was executed; and not only that but that based on what he said, if he wasn't the Messiah, then his execution was justified.
No for some other points
On the cross he was adressing him as father, was he talking to himself?
You ever talk to your self in time of crisis :)
He also said he would not change the law until the end of time.
Actually, he just said "Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled."[1] He also "I have come not to abolish the law but to fulfill it"[2] and then on the cross he said "it is finished"[3] See the connection. Like a contract that is in force until it's terms are complete. Jesus came not to terminate the contract prematurely but to fulfill it's terms.
He did not say I will not change the Law until my servant Paul gets here to straighten you out.
Interestingly, Peter was the first to break the Law.
He saw heaven opened and something like a large sheet being let down to earth by its four corners. It contained all kinds of four-footed animals, as well as reptiles of the earth and birds of the air. Then a voice told him, "Get up, Peter. Kill and eat." "Surely not, Lord!" Peter replied. "I have never eaten anything impure or unclean." The voice spoke to him a second time, "Do not call anything impure that God has made clean." This happened three times, and immediately the sheet was taken back to heaven. - Acts10:11-16
This was after Paul's conversion but before he had met Peter, or even started preaching
Paul wanted to hijack a religion.
As far as Paul and the Law, Paul goes on at length in "Romans" explaining that the Law is still in effect for those who have not accepted Jesus as Messiah
"All who sin apart from the law will also perish apart from the law, and all who sin under the law will be judged by the law. For it is not those who hear the law who are righteous in God's sight, but it is those who obey the law who will be declared righteous."
Here (Romans in general) and in other places (Galatians 3:25 is a good one) Paul presents a duality. You are either under Christ or under the Law. If you are under Christ, he Law no longer applies. If you are not under Christ, you are still subject, and will be judged by, the Law
To clarify: I'm not saying Paul was right, I'm meerly saying that Paul's teaching on the law was more complex than to merely reject it. He actually argued for it under certain circumstances
Please I enjoy talking about this but I do respect your beliefs and commend you for it.
Hey, it keeps me on my toes...and is sorta fun as long as the conversation is kept polite
