When Luther finally received the Papal Bull excommunicating him, he famously burned it--along with copies of Roman Catholic canon law.
On the exact spot where he burned it, just outside medieval Wittenberg's gate (and on the way from the train-station into Wittenberg today) an Oak tree was planted. It remained until Napoleon's troops tore it down when they occupied Wittenberg. Another tree was replanted then, and remains to this day:
“Another tree was planted and it remains to this day”
2,000 years ago the Church was planted and remians to this day. ( although i am pretty sure we are witnessing the great falling away that will precede the end of this age )
