Jesus was crucified and died, once, and that's it. On a particular day, at a particular hour of the day, He died commending his spirit into the hands of the Father, as a once-and-only-once expiatory sacrifice to take away the sins of the world.
The "Lamb that was slain before the foundation of the world" is obviously Christ; but that doesn't mean that Jesus was crucified before the world even began, or that He is crucified over and over. It does mean, though, that His entire oblation to the Father has an aspect which is beyond Time and rooted in Eternity.
Philosophy is not bible...Just because some philosopher thought it up doesn't mean there's an ounce of truth to it...
