The fact that they had this particular letter read at that particular meeting, indicates that they didn't even know what the lesson in the "book study" would be covering that night. It seems that once again, even though they're being guided by the "holy spirit" the right hand doesn't know what the left hand is doing.
I also though it was odd that they asked for $14.00. That amount seems rather specific and it makes me think they wanted it to seem like they were asking for money to cover an exact deficit, nothing less nothing more.
