Our company has an enormous monolith that shares a lot of similarities with this situation. While we are currently road mapping a full migration/rewrite, in the mean time we were able to get all our Sql stuff into source control by generating "create/alter" scripts for every procedure, function, view, and table. So while we still have tons of logic in Sql, it is at least source controlled. This might be a helpful first step, regardless of what happens next, since doing so gives you all the logic for those parts in text files.

I am not trying to start an argument - but your statement about the Greek is factually incorrect. I can read Koine Greek, and the hapax legomena term "theopneustos" (lit. God-breathed) in the Timothy verse is, indeed, a claim to God's authorship. This is purely objective linguistic judgment. It is perfectly valid for you to state that you do not believe that claim to be original or truthful, but it is not valid for you to state that it does not make such a claim. In evaluating anything, we must strive to be as objective as possible without letting our feelings or preconceptions leading us astray.
