Basically it was all about field service and obeying the FDS.
It went down like this.
Shortly after his release from Patmos, John went around visiting all the congregations. At one, he meets a character named Scolios. Scolios is a well to do member of the congregation and some of the congregation work for him. Scolios says Christians should be doing more charitable works rather than more in the ministry work (suggesting that the preaching work is completed).
Naturally John disagrees with him and basically calls him an apostate.
Scolios sends his daughter to another city to work for a Roman businessman. He is very excited because it is a very good job for his daughter and she'll be making lots of money.
Meanwhile, as John is villifying Scolios and yammering on and on about sacrificing comfort and employment in order to go out in the ministry full time, word comes that Scolios' daughter is very traumatized and on her way back home.
When she arrives, she tells everyone that her Roman employer took her to the gladiator fights where she witnessed a boy-friend get mauled to death by lions.
Everyone is humbled and goes on and on about how wrong it is to seek material wealth or to do charitable works and that they should have listened to dear dear John in the first place.
Freakin' barf. Notice that this little "biblical" drama is not to be found anywhere in the bible.
