For when they had come to know God, they did not give Him glory as God nor render Him thanks, but they became absorbed in useless discussions, and their senseless minds were darkened.
with darkened understandings, having by reason of the ignorance which is deep-seated in them and the insensibility of their moral nature, no share in the Life which God gives.
For God did not spare angels when they had sinned, but hurling them down to Tartarus consigned them to caves of darkness, keeping them in readiness for judgement.
And angels –those who did not keep the position originally assigned to them, but deserted their own proper abode– He reserves in everlasting bonds, in darkness, in preparation for the judgement of the great day.
