At the blog, Out of Ur, there appeared a post about the next wave of technology to sweep into churches: holograms. The immediate application would be for multi-site churches who could 'beam' a 3d version of their pastor to all their worship locations.
The article isn't so much an apologetic for this technology as it is a forum for discussion.
Read the comments. The first comment has direct bearing on the 2nd commandment. The other comments address what is lost when one doesn't have a flesh and blood pastor. What do you think?
