[This post is actually Fr. Thompson's.]
His Beatitude Michel Sabbah, the Latin Patriarch of Jerusalem, who was away, was represented by his coadjutor, the Most Rev. Fouad Twal, who was also the celebrant. He becomes the new Latin Patriach this week. The entire Vigil was sung in Latin from beginning to end, including all seven of the Vigil lessons. Readings were all sung according to the traditional Gregorian melodies, as was the Ordinary and Collects. The propers were from the Graduale Simplex to facilitate congregational singing, which it certainly did. Latin Christian Arabs are known for including Gregorian in most of their Masses, even when the vernacular (Arabic) is used, and they certainly sing with gusto. As to the liturgy itself, I think the images and the linked video speak for themselves.
Christ is Risen!
