My wonderful friend Shane Hipps has just published a book called The Hidden Power of Electronic Culture : How Media Shapes Faith, the Gospel, and Church (Zondervan). He argues that the glut of new media (cell phones, the internet and everything else) has had a meaningful and serious impact on Christian theology and worship, not necessarily for worse. He’s a pretty smart cat (and a Mennonite pastor) so if postmodern Christianity is your bag of chips, do check it out.
