You have some idea that a group of men sat around and "made up" Christianity and that is just not true.
Clearly, you are mistaken! I am merely saying that there is NO Biblical precedent for a Council of men to do away with a Biblical COMMAND - Circumcision. Again, I tell you I am Catholic and believe everything you have written so far. However, NONE of it explains the concept of Sola Scriptura. My point is to show you that it didn't exist for the Apostles of Acts 15. That's the fact and there is no arguing against this. Unless you can show me where the Bible tells other Jews that future Jews would have the power to loosen this biblical command, Sola Scriptura was simply not practiced - nor should it now.
