It was a change to better to comply with Caeser.
This just keeps on getting more and more funny!
'To comply with Ceaser' huh? First off, it's funny I have never meet this Ceaser dude, but that's beside the point. If they were 'complying' with Ceaser, they'd pay their tax like they are supposed to. But no, we can't have that now can we? So we have to 'trick' Ceaser (Think theocratic warfare here) into thinking that he cannot tax JWs since they are a 'non-profit' org (actaully it's a non-prophet org - but what good 'ol Uncle Sam doesn't know won't hurt 'em right? )
