Paul always preaches a clear Gospel message true and to the point, he says that Peter was leading believers astray with legalism and hypocrisy (including Barnabus) and then some 40 years later someone writing in Peter's name says these things are hard to understand but this is what Paul meant!
Again this so called Peter is wrong that what Paul says is hard to understand and tries to use intellectual prowess yet fails as he continues to contradict Paul mingling it with truths.
Peter was never the Rock of the church! That's all completely revisionist history dated to 40 years after Galatians and 20 yrs after Peter's death, written by an unknown source in the supposed gospel of Matthew which mingles truth and falsehood and was also written 20 some years after the facts.
Not only that the so called epistles attributed to Peter are known to be actually written by unknown sources again over a generation after the facts.
Bottom line. Trust Paul not Peter. Look at these satanic churches that proclaim Peter as rock!
