Thursday my nun friends invited me to come along to Day 5 of the annual Week of Prayer for Christian Unity .
Every day a different church hosts the community and leads the ecumenical prayer service.
Cenacle, which belongs to all Christians, so to speak, because here was the Last Supper and here the first Christian community gathered and experienced the outpouring of the Holy Spirit on the day of Pentecost.
(May be helpful to enlarge the photo.)
On the right is Father Gregory Collins OSB, who led the service and preached, in ENGLISH!
He is an Irish Benedictine monk of Glenstal Abbey and last year he became the Abbot of the Dormition Abbey on Mt. Zion (see my coverage of that Mass here).
For Christians I can imagine the Upper Room has much spiritual energy.
And one floor below is the Tomb of David where Jews pray, so Christianity's roots are literally underneath.
At one point the hall was also made into a mosque as you can see in the first photo above with the Muslim prayer niche, the hanging mosque lamp, and the Arabic writing on the window.
UPDATE: A short video of the Unity Week's prayer services is now here.
So for ABC Wednesday, C is for Christians communing in the Cenacle.
And the architectural elements are linking to Whimsical Windows, Delirious Doors.
