Today’s Gospel reading is another rarely depicted scene from the life of Saint John the Baptist, but not as rare as might be believed, due to it sometimes being labeled simply John the Baptist Preaching or the Sermon of Saint John the Baptist. Seventeenth-century panels that crop the scene to the essential figures give the clue to reidentifying older depictions. The “priests and Levites” sent by the Jews from Jerusalem (John 1.19) are later identified as being “from the Pharisees” (John 1.24). When John is shown preaching, and there are among his listeners a smaller group of men who are more finely attired, they represent this special envoy. It is not so much preaching, but John the Baptist responding to their interrogation of who he is. Here he calls himself the vox clamantis in deserto, although these words are also quoted in all the Gospels and all point back to Isaiah 40.3. He also says Ego baptizo in aqua and ego non sum dignus ut solvam ejus corrigiam calceamenti. The next day, Jesus came and this moment, when John says Ecce agnus Dei, is much depicted.
