I don’t ascribe to any “systematic” theology theories, but just because lots of people before or after a certain time believed something should be taken as warning sign to not base one’s beliefs on those of others, rather let the scripture and the Holy Spirit be your guide.

I happen to agree with you, but it does weigh in as a factor, especially if one does not ascribe to Sola Scriptura, which itself is not attested to in Scripture. If one comes up with a novel doctrine that has never been embraced for the first 1600 years of Christianity, one must read extremely lightly and be sure that one is not following a different spirit than the one that has led all other Christians up to that time.

2 Corinthians 11:3-5

Wrong.

Jesus appealed only to Scripture in His dealings with the Pharisees, during His temptation in the wilderness, and on the Road to Emmaus when He expounded about Himself to the disciples.

Acts 17:11Now these Jews were more noble than those in Thessalonica; they received the word with all eagerness, examining the Scriptures daily to see if these things were so.

People were commended by God for using Scripture to verify Paul's message.

There is no other source of Truth but God's word. Everything needs to be measured against that to verify.
