What is “Ascension”?

We are reading the Ascension texts this coming week (Acts 1:1-14): Jesus tasks the disciples with their mission, and “Ascends” into the clouds. This doesn’t mean that Jesus is no longer present, however. In the story, the disciples look up where Jesus ascended; two people “in white robes” (angels?) appear, asking why they are looking up and not around? The point is: Jesus doesn’t go away in the Ascension; he becomes more immanently present in more mysterious ways.
