Most interesting that you hold this view. Actually, when you literally read how Acts 15 went down, as recorded by Luke. Peter actually stated this:
11 But we believe that through the grace of the Lord Jesus Christ we shall be saved, even as they.
A literal reading will tell you that Peter is actually saying that he wants the Jews (we), from then on, to be saved, as a Gentile (they).
This is very significant because under the Law of Moses, Gentiles could be saved, but only as a Jew. Exodus 12:48 sums that up well.
And when a stranger shall sojourn with thee, and will keep the passover to the LORD, let all his males be circumcised, and then let him come near and keep it; and he shall be as one that is born in the land: for no uncircumcised person shall eat thereof.
So when Peter announced that, it was of huge significance to all the Jews who heard him during the Council.
But alas, James intervened before it could take root, and he did his final announcement that
19 Wherefore my sentence is, that we trouble not them, which from among the Gentiles are turned to God:
James, in my reading, deftly changed Peter's proclamation about how Jews and Gentiles are now to turn to God, into just the Gentiles.
And Acts 21 confirmed it, especially in v20
...Thou seest, brother, how many thousands of Jews there are which believe; and they are all zealous of the law
In my reading, James kept the Jewish believers bounded to the Law of Moses. And as I have stated in my first reply to this thread, what they bound on earth, was also confirmed by heaven.
So much for the widely taught doctrine that Peter was the head of the church, and James merely supported Peter's decision, as what Adstar would believe. And yes, I cannot see how you could conclude that the 12 apostles had more authority than James. Scripture indicated otherwise.
It is amazing how a literal reading of Acts 15, without the baggage of church doctrine, reveals.
