How to paint Christ

Words of wisdom from William Perkins in his Commentary on Galatians (3:1) [I've modernized the English and spelling.]

Are images necessary in the congregations of the people of God?  Answer:  There are Christian images and pictures, and they are very necessary.  And these images are sermons of Christ and the right administration of the sacraments.  For in them Christ is described and painted out unto us.  As for the painted and carved images of the Papists, we utterly detest them as idols... where the lively preaching of the word is, there is no need of them. 

Why may we not paint Christ in our churches with colors as with words in sermons?  Answer:  There is only one painting that the Lord allows, namely, the description of Christ in speech.  But the carving or painting of images in churches, and that for religion use, he condemns, Exod. 20:6.
