Most of what you said is correct and I agree with, but your definition of "alone" is not quite right.
What a genuine believer means by faith in Christ "alone," faith that "trusts in Christ alone for salvation" (Ephesians 2:8,9) and what James means by an empty profession of faith/dead faith (James 2:14) that remains "alone" (barren of works) is not the same message.
Again, the word "alone" in regards to salvation through faith "in Christ alone" conveys the message that
Christ saves us through faith based on the merits of His finished work of redemption "alone" and not on the merits of our works.
It is through faith "in Christ alone" (and not by the merits of our works) that we are justified on account of Christ (Romans 3:24; 5:1; 5:9); yet the faith that justifies is never alone (solitary, unfruitful, barren) if it is genuine (James 2:14-24). *Perfect Harmony.*
The word of God talks about faith without works, being alone, is dead, lifeless, and without effect. It doesn't have anything to do with faith in Christ's redemptive work alone.
So what kind of faith is "that?" (James 2:14). Empty profession of faith/dead faith that remains "alone" (barren of works). *In James 2:14, we read of one who
says-claims he has faith but has
no works (to back up his claim). This is not genuine faith, but a
bare profession of faith. So when James asks, "Can
that faith save him?" He is saying nothing against genuine faith, but only against an
empty profession of faith/dead faith. *Please listen closely - *James
does not teach that we are saved "by" works. His concern is to
show the reality of the faith professed by the individual (James 2:18) and demonstrate that the faith claimed (James 2:14) by the individual is genuine. Simple!
All the works you mentioned are works of the law or just plain good deeds, which do nothing regarding our salvation, as you said, but you failed to say anything about works of faith.
In James 2:15-16, the example of a "work" that James gives is: "If a brother or sister is naked and destitute of daily food, and one of you says to them, "Depart in peace, be warmed and filled," but you do not give them the things which are needed for the body, what does it profit?" To give a brother or sister these things needed for the body would certainly be a "good work/work of faith" yet to neglect such a brother or sister and not give them the things needed for the body is to
break the second great commandment "love your neighbor as yourself" (Matthew 22:39) as found written in the law of Moses (Leviticus 19:18).
In Matthew 22:37-40, we read: Jesus said to him, 'You shall love the Lord your God with all your heart, with all your soul, and with all your mind.' This is the first and great commandment. And the second is like it: 'You shall love your neighbor as yourself.'
On these two commandments hang all the Law and the Prophets. Please tell me, which good works/works of faith could a Christian do which are completely detached from these two great commandments which are found in the law of Moses? (Deuteronomy 6:5; Leviticus 19:18). Are there any genuine good works that we do as Christians which fall outside of loving God and our neighbor as ourself?
*When it comes to the
moral aspect of the law, you cannot dissect good works/works of faith from the law, so the not saved by "these" works (works of the law) but saved by "those" works (good works/works of faith) argument is bogus.
Works of faith can, in some respects, be synonymous with words of faith. Both require one to believe in their heart and to perform a corresponding physical work that causes the hand of God to move.
Works of faith are still works and we are saved through faith, not works. Paul made is clear that we are
not saved by works (Ephesians 2:9);
not by works of righteousness which we have done but according to His mercy He saved us.. (Titus 3:5); He saved us and called us with a holy calling,
not according to our works.. (2 Timothy 1:9).
Romans 4:5 - But to him who does not work
but believes on Him who justifies the ungodly, his
faith is accounted for righteousness, 6 just as David also describes the blessedness of the man to whom
God imputes righteousness apart from works.
