[...] (and, remember, the word 'heresy' means 'choice") [...]

No, it doesn't. That is its etymology, not its definition or current usage. You'll find its meaning here.

This is definition that I was referencing:

Origin and Etymology of heresy
Middle English heresie, from Anglo-French, from Late Latin haeresis, from Late Greek hairesis, from Greek, action of taking, choice, sect, from hairein to take

First Known Use: 13th century
