Pattern of life (chapter 5)

Paul talked about living the gospel in a new pattern of life by serving one another in love.  The Galatian Christians had been called to freedom.  They should not use this freedom to fall back into fleshy human ways.  They should simply love their neighbor as themselves.  Thus, the whole law is fulfilled in that one sentence about fraternal love.  Paul warned them not to backbite against each other so that they would not end up devouring each other.
