Hunting down heretics this Christmas

I have acquired a helper.  In fact I told Kezia that I was going to train our new puppy to hunt down heretics, to which she replied "What's a heretic?"

So you see, I'm not so obsessed with heretics that my children have learned the Heretical alphabet (A is for Arian, Anthropomorphite and Anabaptist, B is for...) and know their Ebionites from their Samosatians.  The dog however is in training to track down anti-trinitarians of all descriptions, Nestorians and Eutychians.

Remember, a heretic is not for life but should be excommunicated after the second admonition.
