This altarpiece (1508-17) is the work of the sculptor, Master Paul, in the church of Saint James in Levoča, in Upper Hungary (now part of the Slovak Republic). A good deal of individual character is written into each of the faces and figures. Look at Judas, seated across from Jesus, a moneybag slung over his shoulder and an ironic expression on his face.

When I was a kid, we called the Wednesday of Holy Week “Spy Wednesday” in honor of the evil machinations of Judas which set the scene for the eventual arrest of Jesus. Of course we all thought spies were pretty exciting. Nowadays I laugh at that expression (which never had any basis in the liturgy or anything like that), but I do marvel at how Jesus washed the feet of all of them—even his betrayer. That’s love for you.
