Here is a recent article from Lifeteen regarding what it means to be a Christian in this digital age. I think this article displays a nice balance of how to represent our faith and beliefs without having to take part in an online debate. Pope Benedict XVI says,
“confidently and with an informed and responsible creativity, to join the network of relationships which the digital era has made possible . . . In this field too we are called to proclaim our faith that Christ is God, the Saviour of humanity and of history, the one in whom all things find their fulfillment.”
