In Mark 9:9-10, we read about what happened after the Transfiguration. "Now as they came down from the mountain, He commanded them that they should tell no one the things they had seen, till the Son of Man had risen from the dead. So they kept this word to themselves, questioning what the rising from the dead meant."
The Apostles had a problem. Through either lack of faith, or lack of knowledge, they didn't believe Christ would die. Thus, when He said "I'm going to rise from the dead", they had no idea what it meant. And when Jesus died, they were still confused. Finally, He rose from the dead, just as He said. Even then, some of them (*cough* Thomas *cough*) still needed some convincing. What's ironic is that even though the Apostles couldn't understand Jesus' multiple statements that He was going to rise from the dead, those who hated Him knew exactly what He meant.
As a collective, I fear the Church still has this problem today. We have a big problem with allegorising that which ought not be allegorised. When Jesus said "The Son of Man will rise from the dead", He meant the Son of Man would rise from the dead. In the same way, when God said "for in six days the Lord created the heavens, the Earth and all that is in them" (Exodus 20:11), what does He mean? "Well gee, I dunno, maybe it means a magical explosion happened about 20 billion years ago, and God just sat back and binge watched Netflix until humans finally evolved." Does that sound like a feasible interpretation to you? Of course not. When God said He created in 6 days and rested on the 7th, He meant He created in 6 days and rested on the 7th. We don't need to allegorise it.
As a Church, we really need to trust the God of our salvation a bit more. We don't need to bicker over what He means, because He's already said what He means. Have a little faith. We ought not be surprised when the very thing God said comes to pass.
