You left out the possibility (well, historical fact, really) that "Moses" was invented by one of the later kings of Judah, along with the whole "Torah" thing as a way to try and unite Judah and Israel under a common religious banner...<quoted text>
Liam: "So, there are only two possibilities: God lied when He said that the Laws are for ever, or Paul lied when he said that people can ignore the Laws."
OR,... could it be Moses mistakenly THOUGHT the Laws God had given him to deal with his immediate situation were forevermore enacted?
I hope you don't mind my suggesting a third possibility.
However, for rhetorical purposes, I work under the assumption that, if there is any Divine inspiration for ANY of the Bible, then it logically proceeds that the Torah MUST be inspired, or NONE of it hold any meaning.
After all, the New Testament bases its claims on the prophets of the Old Testament. The prophecies of the OT base their validity on the teachings of the Torah, and the Torah claims validity for being the words of Moses as inspired by the God of the Bible. If the Torah is not true, then nothing in the Bible is true.
