[Vicomte13]

The Council of Jerusalem is in the Bible.
Where in the Bible is Sunday specified as the new sabbath?

It isn't.

The other Church councils all have their records to tell us what and where and when. There are no records of the Council of Jerusalem outside of the Bible itself, are there?

The Council of Jerusalem is in the Bible. Where in the Bible is Sunday specified as the new sabbath?

Why does it need to be in the Bible? The Bible never told the first Apostles to write the Gospels nor did the Old Testament say that they could add books to it, but they did it anyway. Where did they get such authority outside of Scripture?

The other Church councils all have their records to tell us what and where and when. There are no records of the Council of Jerusalem outside of the Bible itself, are there?

So...you're saying that it therefore did not exist?

The Church council predates its own written account in the Bible - unless of course you believe that the written account existed in the Bible before the actual council took place somehow or it was made up. Therefore, it was the Church council that decided Christians didn't have to be Jews, not the Bible. If you don't think you have to be Jewish to be Christian, its because the Church said so. Likewise, if you disagree with the Church and don't think the Sabbath is on Sunday, you might as well disagree with the Church's belief that you don't have to be Jewish first before becoming a Christian. You can't logically hold both beliefs.
