More miracle mongering. Gibbon reports enough pieces of the true Cross were sold so that they would float a fleet of wooden ships. That was satire, and meaningless. Several accurate inventories have been done and there is only enough wood in all of the known relics to account for approximately 2/3rds of the patibulum, the cross piece.
"..Accurate inventories..." By whom? When? How conducted? Where are the pieces today? How were the pieces gathered? It says nothing in scripture about gathering the "True Cross." Who states the Roman Government allowed their property to be taken away? In short what is the exact chain of custody of any given piece?
Once again it is miracle mongering as relics are money makers and miss the entire point of Christ's incarnation, death and RESURRECTION. Christ is the ONLY way to salvation not some piece of wood.
