What did paul tell the galatians about the way to obtain salvation and righteousness?

What Paul is explaining is that the Galatians had wandered from the truth that he had first taught them in favour of listening to some judaizing teachers from Jerusalem who insisted that they should still be observing all the rites of the Jewish religion such as circumcision and the ceremonial law with all its feast days etc. These teachers taught that Paul was inferior to the other Apostles where they had come from and insisted that the Law of Moses was still binding and was necessary for justification. This is where most of the confusion originates.
