Checking Oxford, it seems that the words "enorm" and "enormity" entered English (from the French énorme and émormitié) in the late 15th Century. The meaning being, as might be expected: "out of the normal, abnormal".
They were joined by "enormous" (from the Latin enormis) c.1531.
The first noted use of "enormity" with the specific meaning of "menstrous wickeness" is dated at 1538.
The first noted use of "enormous" with the specific meaning of "extraordinary in size or quality" is dated at 1544.
It seems to me the distinction was developing from the start. It ill-behoves us to go against the tradition of half a millenia.
That of courde should be "monstrous wickeness", the other is a matter of theology I don't want to disturb.
LOL! You're gonna make waves!
