I believe it a good thing that we up date our Catechism that God's word will continue to address the world in which we find ourselves in today. The internet alone brings up a lot of new questions that we never thought to address in a specific way before. As an example: how many of our young adults, and older ones too, use the internet in looking for a mate. Even Lutherans aren't just looking in their congregation for a mate any more. Then too we might address some of what is going on in the world in regard to the persecution of Christians. What if that comes to us?
