I have been most strongly instructed by some of your current allies here, as well as by the Reformed that I have dealt with in personal life, that the Gospels are the chronicles of Christ, while Paul is the theology of Christianity. I did a study of the WCF some years back and discovered that there were virtually no primary Gospel proofs of any of the WCF theology. It was predominantly Pauline, and secondarily OT. Read it yourself, with proofs. I believe that Reformed.com has a reasonably good online version. Read the Confession and then read the proofs for each chapter. You may come to the same conclusions that I did.
WCF?
Did you see the link I posted earlier in the thread about the difference between Calvinism and Arminianism?
Reformed theology is not entirely representative of most Evangelical theology.
If you want to go after the Reformed over it, have at it, but it doesn’t necessarily apply to the rest of Christianity.
I would agree that Paul’s epistles are where a great deal of theology comes from, but all of it? I’m not so sure.
