Early church fathers, concordances, commentaries lexicon's and Greek and Hebrew dictionaries are frequently used as excuses for believing in promoting unbiblical doctrine.
If I'm not wrong, "biblical seminaries" promote such things. I know of such learned people that openly teach about Codex Vaticanus, [insert corrupt Bible] as the real text, even openly teach about early "Church Fathers" such as Origen who taught weird stuff, all sorts of unbiblical doctrines.
Here's some of Origen's beliefs I found, which could be helpful for someone reading this.
-Origen believed that man was divine.
-He believed in the pre-existence of souls(As with Pythagoras)
-He taught that everyone, including the Devil, would eventually be saved.
-He described the Trinity as a "hierarchy," not as an equality of Father, Son, and Spirit.
-He believed in baptismal regeneration.
-He believed in purgatory.
-He taught that the Holy Spirit was the first creature made by God.
-He believed Christ was created.
-He taught transmigration (this is the belief that at death the soul passes into another body).
-He denied a literal interpretation of the Genesis creation, taught that it was a "myth" and taught that there was no actual person named "Adam."
-He taught that Christ "became" God at His baptism.
-He taught, based on Matthew 19, that a true man of God should be castrated, which he did to himself.(Eunuchs for the Kingdom of Heaven.. completely out of context)
-He denied the physical resurrection of believers.
None of this is found in the Bible after all. The only familiar place I would find it in is in Paganism/Gnosticism.
If anyone actually studied the Bible for real at those seminaries they'd denounce not only Origen, but probably every other "church father".
