In the lull between Jesus' ascension and the coming of the Holy Spirit, we have two simple stories; angels appear to the 12, and then they must choose a replacement for Judas. However, in these simple stories are familiar elements which bring profound new depths to their simplicity.
We examine the Apostles looking in the wrong place; fancy new Bible words like Shekinah and Parousia; the significance of clouds, angels, and "Men of Galilee"; a ridiculous roll call of the apostles; the importance of women to Jesus' ministry; and Peter's cherrypicking of verses from the Psalms.
It's a lot, and most of it is familiar. But there is profoundness in the familiar!
