"Historically, Christians have differed as to whether the second commandment forbids the use of pictures of Jesus for the purposes of teaching and instruction (in Sunday-school classes, for instance), and the question is not an easy one to settle; but there is no room for doubting that the commandment obliges us to dissociate our worship, both in public and in private, from all pictures and statues of Christ, no less than from pictures and statues of his Father."- J.I. Packer
