Here is the biblical definition of "sinner":

Greek: "Hamartolos"
Definition: devoted to sin, a sinner, not free from sin, pre-eminently sinful, especially wicked, all wicked men, specifically of men stained with certain definite vices or crimes,
tax collectors, heathen.

Here is the biblical definition of "saint":

Greek: "Hagios"
Definition: most holy thing, a saint.

Okay, given these definitions of saint and sinner where do born again believers fit in?

In human terms "saint" is commonly thought to imply perfection, or sinlessness. But, I to not believe that is a biblical defination. If it were, I do not think Paul could have so commonly called humans saints ad in the verses I have referenced above.

My understanding of the Biblical term is those who have concentrated themselves to God. If this is true, then saints are those who are Christians. As we know, Christians stumble and fall.

If saints are those who are Christians, and I am not disputing that, is this only referring to born-again Christians, or does this cover all those professing to be a Christian?

Titus 1:16
Unto the pure all things are pure: but unto them that are defiled and unbelieving is nothing pure; but even their mind and conscience is defiled. They profess that they know God; but in works they deny him, being abominable, and disobedient, and unto every good work reprobate.

I doubt Paul would classify these kind of people as saints.

Didn't Paul begin his letters by addressing all of the recipients of these letters as saints?

"To all the saints in....."

When he said that was he only addressing those whom he considered to be saints, or was he addressing this to all professing Christians, to the whole church of Ephesus, for example?

"To all the saints..." not "to all the sinners." The church is full of wheat and tares, saints and sinners.

Maybe so, but I think Paul was referring to all the saints in Ephesus, or wherever, in a general or corporate sense, knowing full well that there are tares with the wheat.

It is like you writing a letter to the members of the Fredericton SDA Church referring the church members as "To all of the saints in the Fredericton SDA Church" but knowing full well that there is probably tare church members mixed in with the wheat church members. The word saints in this sense obviously refers to all members without even attempting to distinguish or try to judge who are the wheat and who are the tares. Only God knows which is which.

It is obvious to me that Christians are referred to as saints in the respect of one person addressing another person, however, are there any instances where the person identifies himself or herself as a saint?

Here is the text I was referring to:

quote:

---

Ephesians 1:1 Paul, an apostle of Jesus Christ by the will of God, to the saints which are at Ephesus, and to the faithful in Christ Jesus:

---

What is the difference, if any, between the saints and the faithful?

They are one and the same. The Bible authors often used word pairs.
