Since last Tuesday we have been out of the Church, and having Mass in our Parish Centre, ad orientem of course, not just because of lack of space but in a space that is normally used for pastoral rather sacred purposes and having to use a table lower than an altar, it gives a stronger sense of the sacred.
Because of an administrative error we are going to have to celebrate Mass in my dining room tomorrow, ad orientem of course we collapsed the huge table that normally fills the room and have set up the sideboard as an altar. To accommodate the numbers we are going to have Mass at 10 and 12am. The Blessed Sacrament is also there, so it is a bit narrow, we have covered the mirror behind and I shall place my rosary in the top drawer with its reliquary crucifix, under the corporal. I know with Ordinary Form it is not necessary but at least it makes a piece of domestic furniture more like an altar.
Speaking of house Masses, when I was a deacon, I was sent off to neighbourhoods to organise them. Then the priest would come and celebrate Mass on a coffee table or the telly wearing the minimum of vestments, everyone sitting on sofas throughout - how I hate it.
P.S. as for the relics I have never been able to read the minuscule calligraphy that identifies who they are.
