This is the best (the only!) under two minute video that gives a succinct but not heavy theological argument on why we should not make images of Christ, or worse, use them in worship. Posted before but I try to post this when an illicet image crosses my facebook feed and few minutes ago a person posted about their worship service and the overhead was showing an image of Jesus. Since I posted it there I thought those not familiar with it would benefit from it here and to be able to use the youtube link. This was made freely available by Les Lanphere when he determined he did not have a place for it in his Spirit & Truth: a film about worship (which is a great introduction to Reformed worship views and the regulative principle of worship. I'll make a link to where it can be purchased in a later comment.
