Pictures of Jesus Christ
Closely akin to the use of images is that of pictures of Christ. And these, we are sorry to say, are often found in Protestant as well as Roman Catholic churches.
But nowhere in the Bible, in either the Old or New Testament, is there a description of Christ’s physical features. No picture of Him was painted during His earthly ministry. The church had no pictures of Him during the first four centuries. The so-called pictures of Christ, like those of Mary and the saints, are merely the product of the artist’s imagination. That is why there are so many different ones.
It is simply an untruth to say that any one of them is a picture of Christ. All that we know about His physical features is that He was of Jewish nationality. Yet He more often is represented as having light features, even as an Aryan with golden hair. How would you like it if someone who had never seen you and who knew nothing at all about your physical features, resorted to his imagination and, drawing on the features of his own nationality, painted a picture and told everyone that it was a picture of you? Such a picture would be fraudulent. Certainly you would resent it. And certainly Christ must resent all these counterfeit pictures of him.
He was the truth; and we can be sure that He would not approve of any form of false teaching. No picture can do justice to His personality, for He was not only human but divine. And no picture can portray His deity. All such pictures are therefore fatally defective. Like the grave of Moses, the physical features of Christ were intended to be kept beyond the reach of idolatry.
For most people the so-called pictures of Christ are not an aid to worship, but rather a hindrance, and for many they present a temptation to that very idolatry against which the Scriptures warn so clearly.
