Until now, I was unaware of an article on the subject of the hanging pyx, nearly two years old, but which very kindly mentions my humble chapel in France – The Hanging Pyx – a part of the Anglican patrimony. There are a few of them outside England, but I don’t know of any of them being used. After all, opening and locking a tabernacle door is easier than hauling a pyx up and down like rigging on a boat!
I wrote an article about my own hanging pyx and how I made it. They are not found in shops, so you have to adapt something that exists (perhaps a lantern) or make it yourself.
Certainly, it is not very practical if you give Communion to the faithful from the tabernacle. I prefer to give people Communion with hosts consecrated at the Mass. I never have many faithful, so that is very easy for me. The hanging pyx is more of a way of honouring the Blessed Sacrament by “heaving it high”and it being the centre of attention above the altar. It also clears precious space on the altar.
It also represents something of the “northern” tradition as found in England and many other places in Europe until the eve of the Council of Trent.
