Is it right to show our Most Holy Redeemer as a Negro? I feel rather uneasy about it. He was not a Negro.
But I also feel uneasy about medieval and later art showing Him as a Northern European and his persecutors as exclusively people with strongly and stereotypically Jewish Faces..
To show Him and them thus is to do Marcionite art; it is reminiscent of the nonsense peddled by the 'German Christians' during Hitler's Reich, claiming that Galilee was a sort of Aryan, non-Jewish enclave.
He was neither a Negro nor a Norwegian. He was a Jew.
I have always admired the Caravaggio of the Supper at Emmaus (London NG), which seems to me to show Him, fittingly, as Jewish.
It would of course be acceptable to show His persecutors, or some of them, as Negro. And some as Norwegian and some as Jewish. We all crucified Him by our sins, which are many. Yes, even, but not only, Jews.
I crucified Him by my sins, which are many. Mr George Floyd, dare I say so, crucifed Him by his sins, which were many.
Bearded, shaven, long-haired, short-haired? How clothed?
The cultural lingua franc of that area at that time was Hellenistic. He pretty certainly did His teaching, or most of it, in Koine Greek. So show Him whatever way the experts tell you was common among culturally Hellenistic men of the 20s and 30s AD.
As far as personal and subjective aesthetic taste is concerned, I do rather like those jewel-like windows by Sir Ninian Comper (there's one at Walsingham), showing Him sitting in majesty as a clean-shaven young man. And those Pantocrators we see in Byzantine churches, His features sternly set in judgement. I rather wince at representations which seem to me embarrassingly androgynous (which includes quite a lot of Sacred Heart pictures).
Worst of all, of course, are those crucifixes popular among American Episcopalians a generation ago, showing the crucified figure as female. This seems to me the ultimate in Docetism.
If we're going to have controversy, let's compromise on the given and real specificity of the historical Incarnation: that means, on a masculine Jewish Jesus of Hellenistic culture.
