I really think you guys are reading way too much into one chapter, here.
Do you honestly think that James and the Jerusalem council would tell new Gentile converts that it was now okay for them to
1. Worship any of the old gods they had known ahead of the One True God?
2. Create idols of any of the old gods they had known and worship them?
3. Take the Name of the One True God in vain?
4. Desecrate the Sabbath day? (Remember, these men are Jews)
5. Disrespect their parents?
6. Murder?
7. Commit adultery?
8. Steal?
9. Lie?
10. Long for someone else's property?
Common sense would immediately tell us, of course, the Jerusalem council would do no such evil thing as to tell these Gentile converts that the ten commandments...the basis of our morality, no longer applied to them. Obviously, when they speak of "the law of Moses" they are speaking of Levite traditions, they are speaking of such things as Jesus pointed out, like the ritual washing of hands or of utensils, they are speaking of dietary laws...that kind of stuff. To say that they would ever indicate in any way that these new Gentile converts should not keep the ten commandments is tantamount to blasphemy.
Otherwise, we'd still have ancient gods and goddesses in our churches such as were worshiped by them before they converted. We'd have our own golden calves...as it seems some still do.
So saith Angel, the Leader of the Keepers of God's law.
