You paint this as a Morgan/Augustine conflict. But no matter HOW you slice the cookie Morgan's teachings were NOT the teachings of the early church fathers-all of them. Not just Augustine and his cohorts. Augustine's teachings just happened to agree with all the other early church fathers. Morgan and you do not.
I have said about my beliefs that I reject what is commonly referred to as pelagianism.
I have also said that there is decent reason to believe that Morgan of Wales ALSO did not teach what he was accused of teaching.
