Yes, a false teaching or gospel— check out Galatians 1:6-8:
6 I marvel that ye are so soon removed from him that called you into the grace of Christ unto another gospel:
7Which is not another; but there be some that trouble you, and would pervert the gospel of Christ.
8But 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.
The Gospel is, according to 1 Corinthians 15:
1 Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand;
2 By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain.
3 For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;
4 And that he was buried, and that he rose again the third day according to the scriptures:
5 And that he was seen of Cephas, then of the twelve:
6 After that, he was seen of above five hundred brethren at once; of whom the greater part remain unto this present, but some are fallen asleep.
7 After that, he was seen of James; then of all the apostles.
8 And last of all he was seen of me also, as of one born out of due time.
So, if you are not preaching that gospel— the gospel of Jesus Christ— the Bible says “let them be accursed.”
