“I have faith in the gospel as written”
I have faith in Jesus Christ as my Lord and Savior. The be all and end all. The crucified Prince of Peace.
The one from whom all grace flows. The one who saved my life, literally. But clearly as history shows, two people can read the same thing and understand it differently.
If you “have faith in Jesus Christ as my Lord and Savior” then you should believe the Gospel as it records His words. You don’t. You believe in other men’s interpretation of them. That is a defective faith.
