As far as I can recall, Divine Energy<em>can</em>hurt Lucifer, but to actually do anything more than slow him down, you need to be channelling absurd amounts of it. Like, Michael or The Presence levels of power. Granted, he's weaker now through some unknown mechanism, but not to the point where Constantine would be a threat to him. Partly because as far as I am aware, there aren't many spells in the DCU that specifically target Archangels, since...well, Lucifer isn't a Demon, so he's a bit outside Constantine's wheel-house. But the point is that I can't imagine Constantine or Luthor going in and trying to be a dick to Lucifer of all people, if only out of self preservation xD<br/><br/>I mean, Luthor is a Chess Master of epic proportions, but IMHO, in a battle of wits between Luthor and Lucifer? I mean. Lucifer wins. He's literally The Devil. xD
