I found this very interesting, and it goes along with my previous post here.
Bishop Fulton J. Sheen had this to say:
In the history of the world, only one tomb has ever had a rock rolled before it, and a soldier guard set to watch it to prevent the dead Man within from rising; that was the tomb of Christ on the evening of the Friday called Good. What spectacle could be more ridiculous than armed soldiers keeping their eyes on a Corpse? But sentinels were set, lest the dead walk, the silent speak, and the pierced Heart quicken to the pulse of life. They said He was dead; they knew He was dead; they said He would never rise again, and yet they watched! In His Resurrection He has given the earth it’s most serious wound — the empty tomb. And to us our greatest hope. ~ Fulton J. Sheen
Having posted Sheen’s quote here, it may be those guards were set to guard others buried, but never because of fear of the dead rising. Remember also, in those days it was never recorded that His enemies denied what happened that glorious day when He proved He indeed was God. Nor did they ever find what they believed was a stolen body. The truth is Longinus – the centurion who pierced the side of Jesus later converted (as well as many others) and became a Saint within the Church, he is known today as Saint Longinus.
