FWIW: "Good Friday" comes from the obsolete sense "pious, holy" of the word "good". Less common examples of expressions based on this obsolete sense of "good" include "the good book" for the Bible, "good tide" for "Christmas" or Shrovetide, and Good Wednesday for the Wednesday in Holy Week.
Isn't it also Passover? If I remember correctly from childhood, something about the Angel of Death visiting all the homes, taking the lives of the first-born, but "passing over", and sparing the households that had the proper sign painted above the door.
Sounds like selective indictments.
