Yes, Paul strongly emphasizes this because preaching another gospel is a perversion that leads to being accursed.
Paul's warning in Galatians 1 is against any gospel other than what he preached. He calls it a perversion, not truly another gospel. Those who preach such are accursed.
Galatians 1:8-9 — Directly states the curse on anyone preaching another gospel.
In Galatians 1, Paul delivers a solemn warning: "But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed." He repeats this for emphasis. This underscores the severity of altering the gospel message.
Les Feldick stresses that there is only one gospel, which Paul defines in 1 Corinthians 15: Christ died for our sins, was buried, and rose again. Any other message, such as the gospel of the Kingdom, is a perversion. He connects this to Paul's unique apostleship and the mystery revealed to him.
Les explains that most of Christendom preaches the gospel of the Kingdom rather than the gospel of Christ. This is a vast difference leading people down a wrong road. The true gospel is Paul's gospel of grace, centered on Christ's death, burial, and resurrection.
Paul uses strong language, saying 'let him be accursed.' Les notes this is severe because it perverts the only message that saves. He shudders at the consequences for those guilty of this.

Paul's Gospel vs. Peter's: What You Must Believe to Be Saved
Well maybe this is a good time as any, because see, I don't go on a format, so let's just go back to 1 Corinthians 15, it'll make Jerry happy, and it just may open the eyes of someone again that needs these verses, because when I stress all the time that Peter did not preach Paul's gospel of grace, I'm sure there are some out there then, well what is the gospel that I have to believe? Well here it…
Mystery Gospel
Les connects Paul's gospel to the revelation of the mystery kept secret.
What Paul Teaches That You Won't Find in the Gospels
He preached the baptism of repentance, no doubt about it. But Paul says, I�m not. Christ didn�t send me to baptize like He did John. But what is His mission? To preach the Gospel. What Gospel? That Christ died, was buried, and rose again. So to preach the Gospel, not with wisdom of words, lest the cross of Christ should be made of no effect. Then verse 18.
Why Paul's Letters Are the Most Neglected in the Bible
Now the word man is italicized, so it's not in the original. It's been added by the translators. So he says, if any preach any other gospel unto you than that you have received, that is from him, let him be accursed. Hey, now that's strong language. Then verse 10, do I persuade men or God? Do I seek to please men? If I yet please men, then I'd not be a bond slave of Christ.
Only One Gospel
Les insists there is only one gospel, as defined in 1 Corinthians 15.
Galatians 1:8-9: But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed. As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed.
This is the core warning against another gospel.
1 Corinthians 15:1-4: Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand; By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain. For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; And that he was buried, and that he rose again the third day according to the scriptures:
Paul defines the gospel he preaches, which is the true gospel.
Yes, Paul says let him be accursed, which is a severe consequence. Les emphasizes the horror of this.
Les teaches that it's the gospel of grace, that Christ died, was buried, and rose again, as in 1 Corinthians 15.
