Paul's doctrine clearly says one is saved by faith without works.
James' doctrine clearly says faith alone (without works) cannot save.
If it has always been that faith alone saves, then James is a heretic.
James 2 KJV
(14) What doth it profit, my brethren, though a man say he hath faith, and have not works? can faith save him?
(15) If a brother or sister be naked, and destitute of daily food,
(16) And one of you say unto them, Depart in peace, be ye warmed and filled; notwithstanding ye give them not those things which are needful to the body; what doth it profit?
(17) Even so faith, if it hath not works, is dead, being alone.
Neither Paul nor James are speaking against Christ.
But they are teaching a different doctrine of contingency for salvation.
One is contingent on faith with works.
The other is contingent on faith without works.
Different doctrines of salvation. Different gospels of salvation.
If you choose the doctrine/gospel of James, then you are obligated to keep the
WHOLE law. Because if you are under the law, then disobeying any teeny tiny bit of it will pronounce you guilty of the
WHOLE law. And by 'law', I mean the law given to the Israelites through Moses.
For that is the 'works' in which James is referring to - the Mosaic law.
