On Good Friday, having watched the rehearsal for the Passion Play in Trafalgar Square, I went to the Stations of the Cross in the evening in a nearby parish. An interesting invitation was extended at the end of the Stations to visit what was in effect the altar of repose in a Chapel beside the main church. The priest described the Blessed Sacrament being presented in a monstrance that was veiled.
Two things struck me at the time as being "unusual" (by which I mean un-rubrical). One was the idea of adoration continuing from the night of Maundy Thursday, through Good Friday and on into Holy Saturday. There was certainly a very strong sense of the "waiting for the Resurrection", a vigil, but it all seemed to miss the sense of "absence" of the Lord that is the liturgical sense of these days. The second was the idea of using a veiled monstrance for the Blessed Sacrament at the altar of repose.
I was reminded of this when I saw Young Fogey's photographs of the decorations of his Church for Maundy Thursday. The relief of the Last Supper on the altar comes into its own on this day; the last photograph shows a veiled monstrance on the altar of repose.
