Here is the Collect for the Feast of the Ascension:
"O God, whose Son, at his Ascension to the heavens, was pleased to promise the Holy Spirit to the Apostles, grant, we pray, that just as they received manifold gifts of heavenly teaching, so on us, too, you may bestow spiritual gifts...."
The first reading is from the Acts of the Apostles: 1:12-14
"After Jesus had been taken up to heaven the apostles returned to Jerusalem from the mount of Olivet, which is near Jerusalem, a
sabbath day's journey away.
When they returned tot he city they went to the upper room where they were staying,,,"
Then the names of the eleven Apostles are given - I wonder if they were drawn to stay in that room because there Jesus had washed their feet and given them the gift of Himself in the Eucharist and then appeared to them on the first Easter Sunday night and gave them His peace and the power to forgive sins. I hope the owner of the house was happy to have all these men staying in his upper room!
The reading continues by telling us "All these devoted themselves with one accord to prayer, together with some women, and Mary the mother of Jesus, and his brothers."
Let us also prepare for the coming of the Holy Spirit next Sunday by prayer.
