No, it's not. It's the Gospel. I'm sorry Rome clutters it up with so much idolatry and superstition, and I thank God for His free gift of grace through faith to me. Grace saves through faith. Grace is the cause and faith is the means God has chosen to reach His children; to renew their minds and turn their stony hearts to flesh.
That's what the Bible tells us, and those who don't see that fact should pray for new eyes.
The old ones are failing them.
James 2 has half that chapter dedicated to that issue and squarely says that “Faith Alone” is a heresy. That should really settle it; the fact that it doesn’t speaks of the shameful disrespect that the Protestants have for the Word of God.
Yes, I understand the verbal tricks that explain James 2, as well as Matthew 25 away. They are laughable.
