Peter was one among other leaders at this "council" and was subordinate to James
Not what the scripture said. Peter rose, spoke, and all agreed. St. James as the presider, approved the letter.
More bunk! James "my judgment is..." presided and pronounced his judgment.
John 1:42 says "thou shalt be called Cephas", future tense. However, I agree that possibly Jesus named Simon Peter as son as He met him, and in Matthew 16 He explains why. Now, is your argument that the name Peter was chosen without connection to the foundation of the Chruch that Christ said He will build in Matthew 16?
James "my judgment is..." presided and pronounced his judgment
Like I said, "Peter rose (Acts 15:7), spoke (vv 7-11), and all agreed (v 12). St. James as the presider, approved the letter (vv 19-20)." You seem to have forgotten what you are arguing about.
