Of all the points you made this is the only one I disagree with. There is no such thing as "too many people" for a Priest to be able to serve. It's also the primary excuse those who endorse the use of Extraordinary Ministers in this manner.
I struggle to understand why EM's were not needed in the 1950's when people were flowing into the street from churches being packed and as churches have emptied more EM's are required? I have also noticed how people receiving Holy Communion from the Holy Father receive it in the traditional reverent manner. I have never understood why the leadership of the Church post V2 permits almost anything to happen irrespective of what abuses occur in local dioceses?
I think that there is a massive over emphasis on making the modern Church and the Holy Mass "inclusive" with the ultimate result of priests behaving like lay people and lay people behaving like priests. Priests should never be looked upon as "normal men" and should be respected as servants of God.
I have found it odd that that in CM profiles you get comments like "I work in a soup kitchen, visit the sick, volunteer at a Homeless Shelter and am a Eucharistic Minister"- all good things but should lay people be handling the Bread from Heaven? The conditions for use of Extraordinary Ministers seem to be pretty clear within the guidelines (ie in extraordinary circumstances) but they are used in every Mass to make everyone feel included and important. Do the average people participating in this "ministry" know that they are participating in an abuse? I am confident that many do not.
