Holy Ephesian Saints, what does "hagios" mean?

Paul, an apostle of Christ Jesus by the will of God, To the saints who are at Ephesus and who are faithful in Christ Jesus...(Eph 1:1)

Some of us have begun reading Ephesians. We are trying to read the whole letter once a week and then concentrating our discussion on a specific section. Having invested so much well spent time in Isaiah last year, I feel like I will never be able to read the books of the bible in the same way.

The KJV translated the greek word "hagios" as "holy" 161 times, and as "saints" 62 times. I have picked this word out of Ephesians 1:1 to consider the jewish weightiness of its meaning. Paul who I now know to be steeped in the God-given world-view of the prophets is using "saints" in a way completely informed by God through His prophets.

In the New Testament the word "hagios" translated "saints" or "holy ones" has everything to do with the special remnant of Israel. To this remnant we may now graciously be added, not through the "works of the law" like circumcision, but by the obedience of "a loyal recognition" to Jesus Christ. (This "obedience of a loyal recognition" is what most english versions have as "obedience of faith" in Romans 1:5)

"In that day the Branch of the LORD will be beautiful and glorious, and the fruit of the earth will be the pride and the adornment of the survivors of Israel. It will come about that he who is left in Zion and remains in Jerusalem will be called holy[saint]--everyone who is recorded for life in Jerusalem (Isa 4:2-3)."

"Yet there will be a tenth portion in it, And it will again be subject to burning, Like a terebinth or an oak Whose stump remains when it is felled. The holy seed is its stump (Isa 6:13) ."

And they will call them, "The holy people, The redeemed of the LORD"; And you will be called, "Sought out, a city not forsaken (Isa 62:12)."

"I pray that the eyes of your heart may be enlightened, so that you will know what is the hope of His calling, what are the riches of the glory of His inheritance in the saints, and what is the surpassing greatness of His power toward us who believe. These are in accordance with the working of the strength of His might (Eph 1:18-19)."

remember that you were at that time separate from Christ, excluded from the commonwealth of Israel, and strangers to the covenants of promise, having no hope and without God in the world. But now in Christ Jesus you who formerly were far off have been brought near by the blood of Christ. For He Himself is our peace, who made both groups into one and broke down the barrier of the dividing wall, by abolishing in His flesh the enmity, which is the Law of commandments contained in ordinances, so that in Himself He might make the two into one new man, thus establishing peace, and might reconcile them both in one body to God through the cross, by it having put to death the enmity. AND HE CAME AND PREACHED PEACE TO YOU WHO WERE FAR AWAY, AND PEACE TO THOSE WHO WERE NEAR; for through Him we both have our access in one Spirit to the Father. So then you are no longer strangers and aliens, but you are fellow citizens with the saints, and are of God's household, (Eph 2:12-19)
