To try to make such an event into a mere historical fact or a mere historical falsehood or just a metaphor or any other easily accepted and comprehended label is a stumbling block because it denies or ignores the mystery at the heart of the matter.
As I am slowly coming to see it, if it were a simple thing that could be fully comprehended and conclusively decided at the level of our ordinary intellect, then it would just be an idea to reject or accept based on everyday standards for ideas. Instead, events such the Paschal mystery (including that of the Resurrection and the Ascension) are explored by living them out through liturgy and charity.
