Well yeah, because Lucifer is the ultimate misunderstood scapegoat. That's a pretty important aspect of his story.
And unless the argument is that the praise/worship of earthly religious figures actually matters in any tangible way, which we haven't seen to be the case, I don't see its relevance to the question of whether Lucifer or Amenadiel are better suited for the position of God. And the only religious figure who tried to assassinate Lucifer was a murderous, lying zealot, so I don't see how that'd reflect poorly on the former. Not to mention Father Frank took a shine to him, too.
