I'm all for banning someone if they are obviously only on the site to stir up disagreements... and I haven't read every post in this thread, but what I've read so far sounds to be just disagreement about spiritual gifts. That is certainly not a salvation issue...I've been on other sites that will ban such insolent behavior, & they are more peaceful for it.
Blessed are the peacemakers....
But, I suppose if they weren't here most of us wouldn't have anything to do, would we?
The BDF has never been about "toeing the party line".... it is known for rather, um.... vigorous discussions. Which, up to a point is a healthy thing....
