Not nessarily I don't think, but its safe to say you'll be fair game for any Catholic nation to attack. And as someone menttioned in the same thread, you might even fight Crusading armies trying to take your cities as well.

But if your strong enough, I'm sure after defeating a nation a few times they'll make peace regardless of your status with the church.
