You cannot be saved by faith AND works and still call it grace. It don't work that way!!! There is nothing Biblical about that doctrine.
Exactly
That is just your opinion. The scripture however disagrees with you:
Even when we were dead in sins, hath quickened us together in Christ, (by whose grace you are saved,) [6] And hath raised us up together, and hath made us sit together in the heavenly places, through Christ Jesus. [7] That he might shew in the ages to come the abundant riches of his grace, in his bounty towards us in Christ Jesus. [8] For by grace you are saved through faith, and that not of yourselves, for it is the gift of God; [9] Not of works, that no man may glory. [10] For we are his workmanship, created in Christ Jesus in good works, which God hath prepared that we should walk in them. (Eph 2)by works a man is justified; and not by faith only (James 2:24)
The puzzlement you feel is because you either don't understand grace or you don't understand faith, and of course you don't understand works because you think works are works of the law and nothing else. Grace comes from God to you. Faith and works are something you do in response. So no, faith and works are not "called" grace. They are responses to grace.
