Hey I am not the one claiming that a literal serpent/snake beguiled (holy seduced) Eve.
Got you.
The language describes Satan taking on the form of a literal walking "Serpentman" -- speaking, beautiful, walking... -- which caused formerly walking serpents to be forever stripped of their legs to be belly crawlers.
What we have here is a double-entendre.
Being that cherubs/angels take on the form of things, the dragon/serpent seems to be Satans form of preference.
