"Eph. 2:10 turns the "plain meaning" into the Catholic doctrine of salvation through faith by grace sustained by charitable work"
Nowhere does it say grace is sustained by charitable works.
Eph 2:8 For by grace are ye saved through faith; and that not of yourselves: [it is] the gift of God: Not of works, lest any man should boast.
Eph 2:10 For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.
Verse 10 is a resulting clause. We do good works because we have been created in Christ by grace through faith. Grace and faith are gifts from God, not the result of good works, lest anyone should boast. You must be able to do better than that in arguing for a works based grace.
This is your spin. All we read, in plain text, is that works is something "God hath prepared that we should walk in them.". I happen to agree, as does the Catholic Church, that the entire passage gives the primacy to faith by grace, but I, and the Catholic Church read the gospel as written, and it does command us to do good works, -- something we know from other scripture will form the basis of our judgement.
You must be able to do better than that in arguing for a works based grace.
The Catohlic Church does not teach that, so I do not argue for "works based grace". The question was put to you, where does the Scripture teach sola fide, and I still await the answer. This passage doesn't teach sola fide.
Love, just like faith, comes from God as a gift. It is false to say that faith generates love. Love, just as faith, is a theological virtue, a gift of the Life of God Himself within us.
Paul and James tells us that faith without love is dead or useless. Thus, faith alone CANNOT be salvific.
