I'm a bit confused as to how churches became the bad guys in this thread.
I'm also a tad confused about how incorporation in any way contributed to the outlandish "legal" proceedings of a city government so thoroughly off its nut.
And furthermore, I must guffaw at the notion that tax-free incorporation (or lack thereof) will be a serious hurdle for a thing that has not succumbed to the tyrant's brandished steel, the lion's gory mane, etc. Like the United States, the church's greatest enemy is always within. Neither the IRS, nor Houston's City Hall are any real threat to her.
