I've always considered myself to be a heretic. On the other hand, I have never been baptized by either an orthodox or heretical cleric. In fact, the only baptism that I've experienced has been at the hands of Plato (posthumously speaking, of course).
According to Sprenger and Kramer, I would not be considered a heretic, but an infidel. That is, those who haven't been baptized (officially, or otherwise) are infidels. Those who have been baptized, but no longer consider themselves to be "Christian" are considered to be apostates. Those who have been baptized, but who disagree with orthodoxy are considered to be heretics.
So, by this measure, what would you consider yourself to be: orthodox, heretic, infidel, or apostate?
