The little book of 3 John has a neat glimpse into one aspect of the early church: traveling teachers. With John’s calling out of those who receiving them both poorly and well, we also get an idea of the way churches needed to work together in those days. There was no email, no telephone. Letters such as John’s were expensive to write and commoners probably seldom did this. To correctly pass along the good news (and remember that there were also false teachers), it was important to have teachers who spoke the Word correctly move around. Seems like we have it much easier!
