There's also a little ambiguity concerning one of the sins: is it Avarice, or Greed? Wikipedia has the following:
The currently recognized version of the sins are usually given as
wrath,
greed,
sloth,
pride,
lust,
envy, and
gluttony.
I have assumed that it is Greed, which offers a wider scope. It's true that Avarice (like Gluttony) is a form of Greed, so anyone writing about it should be OK. I just hope the reverse is true.
