To DHK:
It is not a matter of semantics mon ami, but rather lifestyle. If one is living carnally, they are living fleshly, worldly, following mere natural instincs, in other words, they are devoid of God's Spirit in their lives.
Then Paul wrote 1Corinthians in vain. You cannot write off their behavior so easily. These were saints in Christ. His letter was addressed to the believers not the false teachers or unbelievers. It was addressed to those who actually lived in sinful practices.
Notice what some or even may of them practiced as they came to the Lord's Table:
1Co 11:20 When ye come together therefore into one place, this is not to eat the Lord's supper.
1Co 11:21 For in eating
every one taketh before other his own supper: and
one is hungry, and
another is drunken.
1Co 11:22 What? have ye not houses to eat and to drink in? or despise ye the church of God, and shame them that have not? What shall I say to you? shall I praise you in this? I praise you not.
--All of them were carnal in this "Love Feast," that was taking place before the Lord's Supper. There was a carnal division between the rich and the poor.
The poor went away hungry and the rich were drunk and gluttonous.
They were divided and Paul pointed this carnal division as well:
1Co 11:33 Wherefore, my brethren, when ye come together to eat, tarry one for another.
1Co 11:34 And if any man hunger, let him eat at home; that ye come not together unto condemnation. And the rest will I set in order when I come.
--They were to come together, in unity, specifically to worship together at the Lord's Table. Satisfying one's hunger was to be done at home. These were carnal Christians and this is but one example. I have given you many. Why do you dismiss them so easily. One cannot throw out this epistle.
The theme verses here is in chapter seven verse one, the first part:
1Co 7:1 Now concerning the things whereof ye wrote unto me:
--He was answering the questions they wrote to him of the continuing problems in the church. They weren't one time events.
In Romans 6, it wasn't a case of one man taking another to court. It was the American way--taking each other to court on a regular basis. You hear of it every day.
--A cup of coffee spills on a lady in McDonalds--sue because it is too hot.
--"Pants Lawsuit" 2005, Pearson sues a dry-cleaning Co. for 40 million because they lost his pair of pants.
--2014 "Nike" A man in Oregon sued Nike because their shoe product could be used as a dangerous weapon. He was attacked by someone using one.

--No different in Corinth. It had become a practice.
These were carnal Christians. It was a lifestyle.
We can read Paul's writing What shall we say, then? Shall we go on sinning so that grace may increase? By no means! We are those who have died to sin; how can we live in it any longer?[Rom. 6:1,2]
Let's get this straight! You are not dead to sin. If you were you would be in heaven.
You are not sanctified. If you were you would be in heaven.
You are not glorified. If you were you would be in heaven.
You are not justified. If you were you would be in heaven.
You are not saved. If you were you would be in heaven.
Obviously all of the above terms have a positional meaning and a progressive meaning. We "work out our salvation." Our sanctification is progressive in which we are made holy day by day. We were justified at the time we were saved. But there are some verses that talk about justification as a completed action in the future.
"Dead to sin" in most verses is an ongoing process, not simply a finished state. To believe the latter show a serious lack of Biblical understanding in this subject.
Paul said:
I die daily.
Every day he put his body to death. It wasn't a one time event.
In Romans 6:11, he said "Likewise
reckon yourselves to be indeed dead unto sin.
--To reckon involves continuous action. It is an action that must be done every day. It is not a one time event.
A.T. Robertson:
Reckon ye also yourselves (kai humeis logizesthe). Direct middle imperative of logizomai and complete proof that Paul does not mean that baptism makes one dead to sin and alive to God. That is a spiritual operation “in Christ Jesus” and only pictured by baptism. This is a plea to live up to the ideal of the baptized life.
This is not something accomplished in the past. It is an imperative to be done now and every day.
(ESV) So you also must consider yourselves dead to sin and alive to God in Christ Jesus.
--Every day.
(Geneva) Likewise thinke ye also, that ye are dead to sin, but are aliue to God in Iesus Christ our Lord.
--Every day.
(ISV) In the same way,
you too must continually consider yourselves dead as far as sin is concerned, but living for God through the Messiah Jesus.
--Every day. It is continuous action.
Rom 6:12 Let not sin therefore reign in your mortal body, that ye should obey it in the lusts thereof.
--Every day, do not allow sin to reign in your mortal body. It is a battle to be faced every day! Why? Because you are NOT dead to sin. You are very much alive to sin.
Rom 6:13 Neither yield ye your members as instruments of unrighteousness unto sin: but yield yourselves unto God, as those that are alive from the dead, and your members as instruments of righteousness unto God.
--This is a command to yield, just as the command in Eph.5 is to yield yourself to the Holy Spirit (continually), which many of us don't. Our members are the members of our body--hands, feet, mouths, etc. Sometimes our mouths still spew out angry words.
And then John's writing Dear children, do not let anyone lead you astray. The one who does what is right is righteous, just as he is righteous. The one who does what is sinful is of the devil, because the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the devil’s work. No one who is born of God will continue to sin, because God’s seed remains in them; they cannot go on sinning, because they have been born of God. This is how we know who the children of God are and who the children of the devil are: Anyone who does not do what is right is not God’s child, nor is anyone who does not love their brother and sister.[1 John 3:7-10]
In both of these small passages of scripture you can see them telling us how we can tell those who are saved and who are not. Those who lived sanctified lives bear the fruits. Those who do not, will show otherwise. If someone is continuing in sin, they are bearing evil fruit, mon ami.
When Paul corrected the Corinthians they repented.
The question you face is a question of time. It is obvious that the Corinthians were,
for some time living a carnal life.
If you sin but one time, that sin is carnal, out of the flesh. Jesus never lost his temper, never cursed, never lied, etc.
The Bible says: "Let God be true, but every man a liar." We all have lied.
Every lie we tell is of the flesh. It is carnal. If I live such a lifestyle it is carnal. But in your theology, or definition when does one lie become "carnal" and give the evidence that I am not saved. When does it turn into a "works salvation"?
Paul spoke to those believers as saved though their lifestyles spoke otherwise. They needed to repent. And they did.
John is speaking of general principles.
Only God knows the heart. John is also speaking to individuals to examine themselves, not with the purpose of criticizing others. He is writing with the purpose here of answering the question: "How can I know that I have an assurance of salvation?" Not, how others can know or how can I know if others are saved. Thus the scripture you are using is out of its context.
Christians can and do sin, that matter is not up for debate. I am sure we both agree with that assessment. However, how long can a Christian reside in sin, live in darkness? If a professing believer dwells in the land of sin, lives a life of debauchery, his life does not measure up to the demands laid out in the bible, it is enough for us to realize something is amiss, mon ami.
"How long" is the question. The bible doesn't say "how long." God doesn't put that limit, and it is up to God, not us. Obviously the Corinthians lived in sin for some time. Paul still considered them believers and didn't bash them in the head telling them they were not saved.
