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.
So, If the bible is not *clear* on a certain topic, it should be held in tension - not used as a foundation to build a set of beliefs that are not clearly taught in scripture.
Phil 2:12
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
