Christ both there and here
On Ascension Day, with the readings from Luke and Acts in danger of being embalmed by archaism, the reading from Ephesians is a gift.

There is arguably no festival or Sunday of the Christian year that is more dependent on mythic imagery than the Ascension of the Lord. The superb narrator Luke is the only New Testament writer to literalize an account of the ascension. Although in the final chapter of his Gospel Luke describes the ascension as occurring on Easter Day, in the Acts of the Apostles he introduces the imagery of 40 days to intensify his story line.
In the scriptures, it is for 40 days that rain falls on Noah’s ark, that the spies scout out Canaan, that Goliath taunts the Israelite army, that Ezekiel lies on his right side, that Nineveh is threatened with destruction, and that Jesus is tempted after his baptism. At age 40 Moses murders an Egyptian; 40 years later he meets with God on Mount Sinai; and 40 years later he dies. For 40 years Israel wanders in the desert and for 40 years suffers under the Philistines. Saul, David, and Solomon each reign 40 years, and every woman is secluded for 40 days after the birth of a son.
Perhaps the origin of this metaphor lies in the fact that 40 exceeds the lunar pacing of 30 days. Forty is a long time. But 40 is also mythically alive, a time pregnant with a religious future. Forty is how long we must wait for God’s intent to be realized. Forty is the metaphysical delay which all humans experience, the legendary period of hope, the duration of either joy or sorrow that opens to emotions unknown. It often takes 40 to open the door.
