Deuteronomy 14:7

Verse 7. Nevertheless there are some which you shall not join to you of those that are the result of deliberation, or of those that seem to be in agreement with spiritual things; as the scientifics professing to lead the soul to heaven of themselves, and the thoughts and affections thence derived (which love to immerse themselves in worldly and sensual things, and thus shut out the light of heaven); for though these seem to be the result of thought and intelligence, they do not agree with the spiritual wisdom which comes from heaven; they are to be shunned as false by the spiritual man.
