Here is a very interesting post by fellow Ridley student, Dave Hughes (although I don't think we've ever actually had a conversation) about the medium and the message of the gospel and how both can and do change over time.

Interesting. Here's a quote to entice you to head on over and read the full post:
What we seem to miss is that the medium is the message. Yes, the Reformers changed the form that the message was being communicated through, but they also changed the message. What makes us think that the message won’t change in this new cultural revolution fueled by the rapid surge in new technology? You change the medium you change the message, you change the message, you change the medium – the two are intrinsically and irreversibly linked.
