What is the Sacrament, Communion, or Eucharist?

I perceive that when Jesus introduced the "communion" of the bread and wine, it wasn't so that we would remember only the person Jesus, per se, but the whole of God's creation, the Universe, that Jesus realized he was One with. It was all his "body."

What is the Resurrection?

I don't think there is any evidence in nature that bodily resurrection can happen. I think this is a misunderstanding of the resurrection.
