I read today that “Good” was translated from the word, “Holy”. The Friday of Jesus Crucifixion was considered a “holy” day for centuries. To me, this makes sense, why we would call it Good or Great Friday, instead of Black Friday, which to my modern sensibities would be more appropriate. A “holy” day because Good Friday was only part of what happened. Good Friday was the beginning, Resurrection Sunday was the end, (and the new beginning).
