Deuteronomy 17:16

Verse 16. And your ruling principle of action is not to be contaminated by doctrinals from the intellectual proprium, nor must the mind be brought back into a state in which doctrine is regarded as more important than life, and religion is made to consist in the intellectual belief in doctrinal formulae and external propriety; for as much as the soul has clearly perceived from the Lord that it cannot be brought to heaven by such means (Apocalypse Explained 654).
