At my church, there are enough people at each mass that several Eucharistic Ministers are used. The Priest “rotates” during the distribution. ERRR Maybe that isn’t the proper word. Each weekend, when the “schedule” is set up, each minister is assigned a spot. And each weekend the priest stands in a different spot, with either the host or the wine.
When I was going through the RCIA, the priest we had then, Fr. Harry, took us on a “tour” of the church. On the alter, in a spot no one could see, except those close to the alter, is a number. That number stands for one of the positions. The alter is on a raised section of the church. I don’t know exactly what it’s called. But it holds the alter, the lectern, the baptismal font and the like. So, it is over the rest of the church.
