Conjugation of Church Nouns

From Huw Raphael's lectionary blog, +Z'ev:

In common usage, eisogesis is one of those irregular nouns. It’s only used in the second person negative:

My book is exegesis.
Your sermon is eisogesis.
Their blog is filled with bloody heresies.

and

These models might come into direct conflict if we see Church as another one of those irregular nouns:

We have church.
You have something, but we’re not sure what.
They have nothing at all.
