No.
But I would question whether that person is saved. Note that Paul writes to his readers as if they are Christians, actual, genuine, sincere converts to Christ. At least some of them are not but Paul doesn't write that way. The Church of the epistolary is a very messy place, particularly in places like Corinth and Ephesus. One man has been having sex with his father's wife (presumably, not the man's mother)
and the congregation knew about it and did nothing. It's not clear from the text, Paul appears to be more upset with the congregation that did nothing than he is with the man committing sexual immorality (which, according to Galatians 5:19-21 would be a work of the flesh that would prevent him from inheriting God's kingdom. Paul wrote something very curious. He directed the congregation (or it's leaders) to hand the man over to Satan so that his body might be destroyed.....
but his spirit saved.
1 Corinthians 5:1-5
It is actually reported that there is immorality among you, and immorality of such a kind as does not exist even among the Gentiles, that someone has his father's wife. You have become arrogant and have not mourned instead, so that the one who had done this deed would be removed from your midst. For I, on my part, though absent in body but present in spirit, have already judged him who has so committed this, as though I were present. In the name of our Lord Jesus, when you are assembled, and I with you in spirit, with the power of our Lord Jesus, I have decided to deliver such a one to Satan for the destruction of his flesh, so that his spirit may be saved in the day of the Lord Jesus.
Now that is an eschatological statement, not merely a soteriological one. I do not know your particular eschatological pov, and there are many different views among us. The "day of the Lord" is a phrase commonly used throughout the entirety of scripture to mean a particular point or time of judgment. In the first century that phrase often referred to the pending destruction of Jerusalem, which all the Christian (especially those who'd heard Jesus preach in person) knew ahead of time was coming. Bot the day of the Lord is also a reference to the day appointed for every man to stand before God and face judgment (Heb 9:27). I'll leave you to decide how you want to read verse 5, but the salient point is that Paul has decided on a course of action that will save the man. Compare that response to how Paul treats folks like Hymenaeus and Philetus (2 Tim. 2). They are treated as people not saved, as false teachers, not authentic or genuine ones.
The matter of the 1 Cor. 5 adulterer's future salvation also brings up another matter because the New Testament also speaks of salvation as something that has occurred, something that is occurring and something that will occur. People are saved, they are being saved, and they will be saved. In other words, salvation is conjugates with past, present,
and future language. Most Christian soteriology recognizes that salvation begins with a specific moment of conversion, continues on through the process of sanctification, and is completed when each of us is raised incorruptible and immortal. Salvation is not a fixed moment, but a process in which we are created in Christ.
Lastly, when it comes to sin, no Christian is perfect on this side of the grave and (generally speaking) one sin is as bad as another to God. All the works of flesh mentioned in Galatians 5 are prohibitive and 1) that lst is not exhaustive, and 2) that list is not hierarchical. Sin kills. There are a few Christians who subscribe to sinless perfectionism but that is generally considered a heretical viewpoint. Christians sin. Paul sinned after his conversion. So, too did Peter. Neither of them committed adultery but Peter is recorded to have behaved in a hypocritical manner so severe that some left the faith. "
Woe to that man by whom the offense comes." Church leaders (shepherds) are held to a much higher standard than the sheep (
Jms. 3:1). Yet never did Paul treat Peter as a non-Christian, an outsider.
If the sexually immoral man of 1 Corinthians 5:1-5 was building on the foundation of Christ, then he was saved. All his works would prove to be worthless and become incinerated when facing God, but according to Paul the man will be saved. Note that Paul wrote those words assuring salvation earlier in the exact same epistle. It is reasonable, therefore, to think Paul might have been providing an example of what he'd written earlier. However, the rest of chapter 5 is very harsh. Paul directs the Corinthian congregation to remove the evil person from among them, which would mean Paul considered the man evil, specifically because he was behaving in a sexually immoral manner. I will add a personally anecdotal report because, as a professional counselor who specialized in marriage, trauma, and addiction, most sexually immoral people don't commit sexual immorality only once. A man who will have sex with his father's wife will likely have sex with anything. That guy (or gal) is not saved.
One of the great paradoxes of Christianity is that Hitler, Roosevelt, Churchill, and Stalin all might be in the same exact place right now. If, in the moment before that bullet passed through his skull, Hitler repented, begged for forgiveness, and called upon Jesus as his Lord and Savior then he's in heaven. That's not likely, but that is possible. Likewise, even though Churchill fought against Hitler and his evil regime, Churchill fought on the side of "good," but the fact remains if he did not know Jesus as his Lord and Savior then he is in hell.
Doubt is a normal part of Christianity. We are saved by grace. The chief task for us to perform is to
believe. No matter what else happens in your life or mine we are to believe in Jesus. If you and I believe in Jesus for our salvation from sin and wrath with our last breath we are saved. That being said, faith is supposed to beget faithfulness. A faith that does not affect faithfulness is a fruitless faith and the purpose of our being created in Christ is so we will perform good works (Eph. 2:10). That is why scripture places so much emphasis on what we do (or are supposed to be doing), beginning with loving God and loving others. The apostle John also wrote to address the matter of doubt and assurance when he said,
1 John 5:1-15
Whoever believes that Jesus is the Christ is born of God, and whoever loves the Father loves the child born of Him. By this we know that we love the children of God, when we love God and observe His commandments. For this is the love of God, that we keep His commandments; and His commandments are not burdensome. For whatever is born of God overcomes the world; and this is the victory that has overcome the world—our faith. Who is the one who overcomes the world, but he who believes that Jesus is the Son of God? This is the One who came by water and blood, Jesus Christ; not with the water only, but with the water and with the blood. It is the Spirit who testifies, because the Spirit is the truth. For there are three that testify: the Spirit and the water and the blood; and the three are in agreement. If we receive the testimony of men, the testimony of God is greater; for the testimony of God is this, that He has testified concerning His Son. The one who believes in the Son of God has the testimony in himself; the one who does not believe God has made Him a liar, because he has not believed in the testimony that God has given concerning His Son. And the testimony is this, that God has given us eternal life, and this life is in His Son. He who has the Son has the life; he who does not have the Son of God does not have the life. These things I have written to you who believe in the name of the Son of God, so that you may know that you have eternal life. This is the confidence which we have before Him, that, if we ask anything according to His will, He hears us. And if we know that He hears us in whatever we ask, we know that we have the requests which we have asked from Him.
Christians worry about their salvation sometimes. It's a paradox because, according to Paul...
anything not done in faith is a sin! So I reiterate: your salvation is not yours. It is God's. God is the one who saves the sinner from sin and wrath, not the sinner. God is almighty and if He has saved a person then He will finish that task. If you and I have genuinely been saved then God has saved, is saving us, and will save us.
