I have no problem with depicting Jesus or Mary with sinners. A painting of Jesus with His hand on the head of George Floyd or addressing a crowd about to throw stones at him would be poignant and remind us that every single one of us is a sinner. "Let he who is without sin cast the first stone."
A painting of Mary with George Floyd wrapped in the folds of her mantle would remind us that she is not only Theotokos, Mother of God, but the refuge of all sinners. "Am I not here, I who am your Mother?"
But to depict George Floyd as Christ with a halo seen in many of the Christ icons is blasphemous. George Floyd was a drug addict and a man who aimed a gun at a pregnant woman's belly targeting the baby in her womb. He had a fatal level of fentanyl in his system when he died according to the coroner's report. Is this the man to portray Jesus Christ, the God-Man?
The students protesting this blasphemy at Catholic University are right. The school is trying to distance itself from the reality of what it portrays. But it's clear that the artist meant the Christ figure to look like George Floyd from his cropped haircut to his facial hair.
For more, see the article below and the articulate undergraduate Junior discussing the blasphemous painting. How can God bless us when Jesus is treated this way? The same for Catholic joke memes that make him a joke. I recently saw a cartoon that showed him kicking over the tables in the temple over a Monopoly game. My colleague at RestoreDCCatholicism has addressed this and she is absolutely right. Our faith is not a joke.
