Exactly. Some Baptist successionists claim that the Paulicians of the 7th-9th centuries were Baptists. This claim is ridiculous. The Paulicians believed that the God of the Old Testament was an Evil Spirit (aka “the demiurge”) and thus they removed all of the books of the Old Testament from their Biblical canon. They also believed hat Christ came down from heaven to emancipate humans from the body and from the world. They also rejected the Trinity.
The Paulicians of the 7th-9th centuries had almost NOTHING in common with the Baptists of today. They had more in common with the earlier Marcionites (and various Gnostic sects) as well as the later Nazis, who also tried to remove the so-called “Jewish parts” from the Bible.
