Bingo! We've seen evidence of that on this very thread. They dismiss Paul; they call him a Gnostic; they say He is not part of the Gospel message; and most of all, they forget he was chosen by God to preach Christ risen.
Next to Jesus Christ, who has given us a more certain testament to God's truth than Paul?
The fact that Paul articulated the Good News so clearly is part of what they resent. It doesn't jive with their unBiblical mumbo-jumbo.
To the contrary.
We consider Paul to be the second greatest of all the Apostles. We dismiss Calvin and call his followers Gnostics and Marcionists.
It is certainly indicative of the shakiness of your foundation when misinterpretation of Paul is all that you base your theology on.
