Well...
“For the Son of Man is going to come in the glory of His Father with His angels, and WILL THEN REPAY EVERY MAN ACCORDING TO HIS DEEDS.” (Matthew 16:27)
Now, to be completely clear: People are ONLY saved by grace, but they receive that grace through faith and God’s works begun within them.
Like everything else, our good works is a gift given to us from God.
Well stated, the only Alone that one can 100% affirm by Sacred Scripture and Sacred Tradition (as expressed via Councils and Fathers) is Grace Alone. It is God’s Grace by which Humanity is saved. Faith is a Theological virtue which is connected to Grace, but so is Love and Hope, which are along with Faith are lived virtues to also be lived out.
However, as several posters noted, it is clear that many Americans who profess Catholicism on one hand or Protestant Confessions on the other are totally confused as to what their respective Traditions teach.
