At the same time that the Philadelphia group is promised protection, the Laodicean group is found so distasteful, so unqualified because of a lackadaisical, seemingly couldn't-care-less, worldly, sitting-on-the-fence, neutral attitude that is nothing less than idolatrous.

They are to be spewed out for the purpose of going into the fire.
