In the early Church, lay ministers of Holy Communion were used as the Bishops, presbyters and deacons were just beginning to develop. They didn’t require 10 years of study to become a priest, and especially not a deacon. They just had to show their commitment in serving Jesus Christ and His Church.
As the Church grew in the West and got in the power structure of the Empire, more men joined the priesthood, often out of mandates from their parents. Often, Bishops and Cardinals came right out of the Laity through political favors between nobles and the Pope. Things were not nice and clean as some Catholics like to believe.
When I was a kid, the parishes in my area had five priests on average. No deacons as the diaconate had not been reopened.
Today, only one priest and a deacon is the average and in some cases, the one priest serves two parishes. as my former pastor had to do.
So, the need for EMHC’s, is needed and the parish priest under the direction of their Bishop, ask’s the laity in the parish to serve as EMHC, Lectors and Altar Servers.
This is the Holy Spirit at work, despite your distates for it.
