There's plenty of Protestants who believe Christ's teaching wasn't meant for us. And plenty who think you were born saved or doomed.
"The Gospel for Protestants" is all over the place. "Preaching a different Gospel" is what happens when you leave the Church.
Don't think there's so many. Now...if you're talking Paul's teachings...yes there are plenty of mainline Protestants who deny those. But plenty of Catholics do too.
