Now, "zombie", as I know it, refers to a person who has been resurrected from the dead by means of evil, sorcery, or any other type of magic. Generally speaking, I believe the term to be associated with Vodou (voodoo) beliefs. So the first question to pop into my mind was, "Why are zombies being discussed at AWANA, during class time?" Our faith is not in Vodou.
The Little Leaguer stated the scripture being talked about was when Jesus was on the cross and the sky went dark as night, though it was afternoon, and the earth shook. Being familiar with this event, I said, "Yes, that is correct." The Leaguer went on to say this verse also speaks of dead "Romans" walking around. (The sound of a needle scratching off of a record.) Now you've lost me! But hey, I'll look it up! First, I'll check with Luke since he was a physician.
It was now about the sixth hour, and there was darkness over the whole land until the ninth hour, while the sun's light failed. And the curtain of the temple was torn in two. Then Jesus, calling out with a loud voice, said, "Father, into your hands I commit my spirit!" And having said this he breathed his last. Now when the centurion saw what had taken place, he praised God, saying, "Certainly this man was innocent!" And all the crowds that had assembled for this spectacle, when they saw what had taken place, returned home beating their breasts. And all his acquaintances and the women who had followed him from Galilee stood at a distance watching these things. (Luke 23:44-49 ESV)
Nope. No "zombies". Let us see what Matthew recorded.
Now from the sixth hour there was darkness over all the land until the ninth hour. And behold, the curtain of the temple was torn in two, from top to bottom. And the earth shook, and the rocks were split. The tombs also were opened. And many bodies of the saints who had fallen asleep were raised, and coming out of the tombs after his resurrection they went into the holy city and appeared to many. When the centurion and those who were with him, keeping watch over Jesus, saw the earthquake and what took place, they were filled with awe and said, "Truly this was the Son of God!" (Matthew 27:45, 51-54 ESV)
Okay, I see where Matthew mentions "many bodies of the saints were raised". And, to confirm what Matthew stated, I checked in Mark. His account was just like that of Luke. So, what in the world was Matthew describing? It sounds like a "Lazarus" type thing but he does not go into detail. All I get to work with is, "Many bodies of the saints who had fallen asleep were raised, and coming out of the tombs after his resurrection they went into the holy city and appeared to many." So, I looked to Pastor John MacArthur who answers this question in his "God's Miraculous Commentary on the Cross". He actually has a lot to say regarding this scripture and I HIGHLY recommend you check it out at http://www.gty.org/resources/sermons/2397/gods-miraculous-commentary-on-the-cross.
There was a resurrection, folks. There was a resurrection. Did you get that? You say, "What came out of the graves?" Somata, bodies, bodies, not spirits. This isn't some ethereal thing. These aren't ghosts. Bodies, this is a real resurrection. What bodies? Many bodies...not all of them, it was a very discriminating one. Only select ones. Who were they? Saints. What are saints? Holy ones...from out of the Old Testament era who were waiting for their resurrection, who had been waiting perhaps a long time. When Jesus died, their spirits came from the abode where righteous spirits dwell and were joined with glorified bodies that came out of those graves.
You say, "Is this a real glorification? A real resurrection?" Absolutely. So many people who know the story of the cross, miss this. This is important. This is another statement by God. This is a resurrection, a real literal physical bodily glorified resurrection.
But what happened? They came out of the graves..period. The next sentence says, "After His resurrection, they went into the holy city and appeared unto many." Can you imagine what kind of testimony they have? "We have a guest for dinner tonight, you won't believe this..." ((c) John MacArthur, Grace to You.)
So, "zombies" in the bible?! No. But the miraculous promise God has made to us, His saints? Yes! Resurrection!
